Calls and texts on other devices not showing - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

Does anybody have the tab s7 + from sprint/T-Mobile and the feature of calls and texts on other devices that should be in advanced settings not there? If are all carried tablets have the feature not able to be enabled? If it is that way does anybody know how to change it so it could be enabled or is it the settings apk?

The U.S. carriers really hobble Samsung's tablets. What you're looking for is removed as are the native dialer and messaging apps. I bought mine in the EU so that those features were available along with it being bloatware free. The downside is 5G only works on AT&T because the 5G bands supported in the EU are different than in the U.S.

Same i tried finding it and couldn't find it in settings anywhere. Its on my phone but not the tab s7. Tmobile removed this feature? It was on my wifi tab s6 but not on the tab S7

I talked to a T-Rep\Tech they claim that it show be in the settings. I also keep looking and found that ATT\Verizon are the only ones that disable that feature in settings on samsung's website along with supported models it doesn't list the tab S7/+. If t-mobile disabled it by software/settings then would it be some way to edit somethings internally and settings in order to get it?

It's either there or it's not. If it's not it's because T-Mobile removed it. It's on my Tab S7+ 5G from the EU. I don't buy U.S. cellular tablets because of all the features they exclude and all the crapware they include.

Oh I see since it's all in software. Would I be able to flash the software version the EU S7+ 5G in order to get all the features that my T-Mobile version have been disabled on?

Ah damn. It's probably not only apk for it but the framework too? And now it's too late for me to send this one back and buy one from EU since I've already sent in my trade in device. Really sucks. I found the call and texts on other devices apk found that it installed the options showed up after a reboot but no dice after trying to send a text received "Unable to send message - Message blocking is active . Looked for the phone apk as well but seems to already be installed. My guess I when root become available the build.prop can be extracted from EU and there's probably something that needs to be enabled in order for it to work properly.

On my Tab S7+/T-Mobile I do not see the Call & Text on other devices settings. I do see the dialer app is installed, just not accessible. Since the Samsung site does not list any 7+ model (LTE or WiFi) as compatible with this feature, I would guess Samsung disabled this, not T-Mobile. Too bad their marketing material says it is compatible.

I'm guessing its a samsung US S7+ 5G issue. Samsung sites says that AT&T and Verizon doesn't support the feature. The samsung S7+ from the UK supports it tho. Hopefully it's a software issue that samsung can push out with enough complaints.

Wish it was available for non samsung devices too

+1 love the tablet, hate the phones. I'm a oneplus user for now

I didn't realize this feature had been removed but I bought an S7 anyway. After taking a look around, I noticed the phone dialer is installed if you go to settings>apps you'll see it there but there's no way to actually launch it. Further digging using SetEdit app shows "cmc_activation" in Global Settings but I can't change the "0" to a "1" due to the fact the app does not have write permissions.

What about the Us Cellular version since that already sim unlocked? Maybe some can try flashing the USC rom

i have the ATT version of the S7 and preloaded is ATT Numbersync (Dialer & ATT messages app) connected to my main ATT phone (Galaxy S21 Ultra). Originally activated on ATT on its own data plan. Phone dialer and ATT messages worked as a clone to my main number.
However, upon ATT supplying the network unlock code, I started to use the S7 with my T-Mobile SIM
and all continued to operate exactly as above , still sending and receiving calls (via Dialer & Messaging App)
but still cloning to my main ATT number, etc. Only now on 4G speeds and using T-Mobile network.
I am afraid to do a factory reset as I dont want to lose the phone calling feature or get stuck not having the ability to attach it back to my ATT line.
This is the only way I know of to keep the tablet to use as a full featured phone/data device by utilizing ATT software when using with a differet network that dosent configure their versions for simple phone use.
'Call On Other Devices,' is loaded on their WIFI versions only since it connects through your samsung account ?
I know it was loaded on the Tab S6 Lite - Wifi version.

i left all original ATT firmware. i think its the only way it will allow numbersync to stay active allowing me calling and text.
howevet i did d/l a seperate mess app to allow tmobile messages to come through
in conjunction.
whats strange is weeks after I did this, my tablet now shows a 5G speed / logo
with speed test hitting near 188mb

So, I think I have a workaround for this. It looks like the S6 version of Call and Text, meaning that everything goes through your Samsung account - not across the same network as promised in the S7/S7+ marketing. Not without its quirks, but I have it enabled. Steps:
(1) If you have used the Messages app, delete or back up your conversations. If you don't, when you have reached the end of these steps anything you send to those contacts will still come through your tablet phone number and not your phone's number.
(2) On your phone, remove any devices from Call and Text that you no longer use. This is especially important if you rename your devices because the duplicate names will show up but the entire thing will have some sort of cerebral hemorrhage and nothing will work right.
(3) Go to Settings -> Accounts and Backups. Back up your Messages and Call Logs - for some reason, this process will not bring these over to your tablet, so this step allows you to get this base data over to the tablet. From then on, everything will stay in sync.
(4) Download and install the Call and Text on Other Devices APK from APK mirror. I used the latest one from May 1.
(5) Restart the S7+.
(6) Make sure the tablet is logged into the same Samsung account as your phone.
(7) Go to Settings -> Advanced and enable Call and Text on Other Devices. When you do this, you will get a prompt asking you if you want to switch to the Samsung dial app - by all means say YES! This will reveal the dialer app in the app drawer.
(8) Now go into Call and Text on Other Devices to adjust settings. You will see that calling is not enabled, so you want to enable it. When you do, you will get the same prompt about switching to the Samsung dialer. Again, say YES!
(9) Adjust the other settings as desired.
(10) Restore your call and message logs on the tablet.
(11) Back on your phone, you should see your tablet as a registered device.
Some of those quirks I mentioned:
Outgoing calls work just fine. Sometimes incoming calls do not ring. The record of the call will be there, but you might not get notified the call is coming in. In my limited testing so far, this happened about 3 out of 10 times.
If you don't delete message conversations made with your tablet prior to setting this up all future messages will still come from your tablet's number even if you select new and add the same contact.
I've been using this for 2 days now, and so far, mostly great. Nice to have this feature back even if I had to brute force it.

I sideloaded the call & text app on my T-Mobile S7 plus. Messaging works but you can't make calls. I'm assuming there are other APKs to sideload to get the calling function to work.

[Q] Making phone calls with the galaxy tab 10.1v??

Hello guys,
does anybody knows how to make phone calls with the samsung GT-P7100 galaxy tab 10.1v? got my simcard in it and dont know how to call, sending smses, and how to get all my contacts on my tab wich one i got on my simcard?? are there any apps for it ?
Kind regards,

To get contacts, sync your contacts to GMAIL then sync your gmail account.
Search the appstore for textfree with voice. Or just use Google Voice.

But the phone contacts in GMAIL. And I think that if you email someone's phone at their service provider, it will be sent to them as an SMS.
Code:
[email protected]
For an example. I'm 90% sure that's correct (can't remember where I read it), so try it out on your phone first. Tell me if it works!

dont think this will work, there was someone on a dutch forum asked the same, but samung made a mistake on there website about the discription. in the discriptions they were saying you can call and text someone trough your provider, so one off them contacted with samsung and they said it was a mistake on ther website
Oh, IDK then
so,ok i'm confused.
is there a way to make phone calls with the 10.1v? I mean with the sim card and a dialer and all.
otherwise i don't get it why they have a handsfree with the device...
I'm kinda interested in this too.. the tab 10.1v didn't come with a dialer app, when other apps tied to make a phone call I just get a prompt asking if I wanna save the number in my contacts and that's it.
ironically according to Vodafone AU, they encourage you to use Skype or VOIP to make phone calls...even the plan for the Tab is data only (although if you put the SIM in another phone you'll be able to make GSM calls at exorbitant rates).
P.S. the handsfree is for VOIP/Skype dialing - or so as it was intended by design.
The android 3.0 is only for tablet, no phones at all, so this OS is not designed for mobile phones, so all android 3.0 tablet cannot make a phone call, as well as moto Xoom.
However, some guys may crack this operating system and add some codes( something like that ) and make the tablet can be calling. As far as I know, moto Xoom can make a phone call but it is unstable. Perhaps we need more people to get this tablet to develop this phone call function

I'm not so sure that's true... I'm pretty certain that Honeycomb is quite capable of making and receiving phone calls, but I doubt that carriers want that functionality for all the same reasons that US carriers gimped the US versions of the 7" Tab. Selling a single device that "does it all" is bad for business.
If you look in this video, you can see at various points where you're given an option to make a voice call, and in the settings screen, you have a "Call settings" option in there, but whether or not we will actually be able to do that when the device is released, is another question altogether...
Samsung Galaxy Tab 8.9 live first look
I'm also interested in this (wither the 10.1 Tab is able to do voice calls).
For the guy who said "Honeycomb cant make phone calls"
http://www.gsmarena.com/samsung_gal...eview_amazingly_packs_telephony-news-2709.php
Appearntly the Samsung Tab 8.9 is able to do voice calls, you can do it using your contacts, .. or by using a 3rd party dialer from market.
The Samsung Galaxy Tab 8.9 has just arrived in our office and, boy, do we have some news for you. It turns out that the Honeycomb slate takes on from where its 7” predecessor left off, and brings native telephony capabilities to an even larger form factor.
Yeap, we are talking regular GSM network phone calls and even some video-calls if you wish. There’s no dialer on board, but you can either get a 3rd party app from the market (as we did), or use your contacts list for initiating calls.

I don't think we're talking about making phone calls with a 3rd party VoIP services like Skype or Tango. We're talking about making native GSM carrier switched phone calls in exactly the same manner as you can with the 7" Tab (and regular ol' mobile phones of course).
GSM? Please say yes.
Been using my 7 inch with ATT and rotohammer's rom on it to make calls since the device was released. I would love to get the 10.1 but can't see going back to using two devices, voip is not an option.
My two questions:
1. Will ATT be carrying this device
2. Can it be modified to use GSM phone service, (not skype)

this is an old issue that we have found out how to work around. Get the tethering plan and they don't mind you using you tab as a 'do everything' device. It was the iphone unlimited data plan that made the execs at att get their big girl panties in a wad. You have to be willing to pay for it, which I am, but it works great. Now, back to my questions, aside from att issues, does the 10.1 device have the ability to be used as a gsm phone?

Well, I guess that's my issue then; I'm not willing to let go of my unlimited data plan (either of them) so, I'm just using it as a data only device for now with my Laptop Connect SIM instead.
Back on topic though, as for being able to use the 10.1(v) inch tab as a GSM phone, from a purely hardware standpoint, there's no technical reason why it can't. Even GSM/UMTS devices which are branded as "data-only" devices, such as aircard modems, are capable of making and receiving ordinary GSM phone calls, provided you have the right software to utilize those functions. (I should know, I used to make regular phone calls from my Sierra Wireless 870 all the time). Now, whether or not carriers will allow the manufacturer to ship their devices with those calling abilities out-of-box, is an entirely different matter...
So, to summarize:
Is the Galaxy Tab 10.1, 10.1v, 8.9, etc. capable of making and receiving GSM phone calls the same way a GSM phone can? Yes, probably.
Will carriers support this innate hardware capability and allow users to make and receive regular GSM phone calls to and from their tablet devices? Probably not.
That's why I brought up my older post. Not because it isn't still an issue for that specific device, but rather because it's still an issue on the principle that US carriers (not just AT$T), apparently will deliberately cripple new technology in order to force us, the consumers, into buying more of their crap when we don't necessarily need to. E.g. forcing us to buy two line subscriptions, one for data, and one for both voice and data, when one line subscription would have been perfectly ample to suiting our needs, had we been allowed (officially) to use tablet devices as GSM phones as well, and switch freely between the two.
Jus got a 10.1v. For sure phone calls are not supported. But for sure the hardware supports it. Its just "CLOSED" for this tablet via software.
I am sure some cool developer can sort that out pretty soon for us though.
Really would want this to happen.

Any luck setting up AT&T NumberSync?

I've searched the different forums for the S3 without luck, so please if this has already been answered let me know what thread.
I am moving from an AT&T branded Tab S to a US Cellular branded Tab S3 on AT&T. I've asked and confirmed they updated the IMEI on the AT&T side to reflect the Tab S3. What I would like to do is get the same calls and texts on the Tab S3 as my S8+. I know I can get other apps like Google Voice to make calls but I would like to connect the Tab as the primary bluetooth device in my car (along with other reasons) so would like in those cases to just use the Tab for all actions.
I know the Tab is not AT&T branded, but wasn't sure if the AT&T Phone Tablet apk has been extracted and possibly installed on another unlocked device.
Have you checked any of the apk sites like apkmirror?
AFAIK there are no phone apps for tablets. The Galaxy Tab S3 I have doesn't have a SIM card but I see the uscellular site has 4GLTE version but my understanding is that is data only, not phone calls. You would have to use any VOIP app like Google Voice, Hangouts, Allo, etc to make "calls" but as a phone and receiving phone calls I don't think the Tab S3 can do what you want unless you are on Project Fi and can use hangouts to receive calls. I know when Project Fi gets a call on my number I can also have hangouts ring on my tablet. But I think that is Project Fi specific. I'm not aware of any ATT app that can provide that functionality.
Thanks @aspexil I was looking for something similar to what the AT&T branded Tab S has. There's a phone app that when clicked launches their NumberSync configuration so calls from your phone can be routed to the tablet if needed. I'll check apkmirror and see if anything comes up!
@alfredtv if you still have the Tab S you could get the apk from there? There are plenty of tools and sites that describe how to do that even on a non-rooted device. Good luck it sounds like a neat app.

Call & text on other devices not always working

For some reason the call and text on my Tab S7+ and S10+ isn't always working. When I make a call using the Tab S7+ I see a message saying "No network connection" but on my S10+ the call is being made but hangs up because it could not transfer to the tablet. I can't get any incoming calls either but get a missed call notification after they hang up. I cleared the cache and data on both the phone app and call & text app and it worked for a day. Now not even clearing the cache and data works. I don't know what the issue could be. Anyone have these issues?
I have the sprint version of the Tab s7. There’s no option to turn on calls and text from other devices. It came with a messenger app but no dialer. I’m confused. Am I unable to make Calls. I have the note 10+
That's another strange issue. Does Spring allow this service? I read that some providers in the US don't support this feature. I'm still having issue getting it to work 100%. I even cleared the cache partition on my phone thinking there might be something in there that is corrupt. Funny thing is sometimes I make a call on my Tab S7+ and get the no network connection but after a minute or two my phone stays its making a call from the Tab S7+. So there is a delay for some reason. Could this be something with the Samsung servers?

They said Verizon and ATT doesn't have the feature. I dont even have a phone dialer. Sprint told me to contact Samsung. Samsung said its sprint.
What I don't understand is why does it matter what service provider you have. From my understanding this feature works like this; (1) I make a call on my tablet (2) it goes through my home wi-fi to Samsung's server (3) Samsung server sends the number to my phone and initiates the call.
So why would the service provider care or even know if I directly make the call from my phone or it gets remotely dialed by Samsung.

Well I had a chat with Sprint again and they said the service has been disabled on all their tablets. I would have to download a 3rd party app to make calls. It does have a mess
Disabled on the T-Mobile S7+ as well. Went in through ADB and could not find the packages for this anywhere. Samsung said in marketing this tablet that it was not available on the Plus at launch, but that was the fine print. Just above that it said it was available, period. Hoping it shows up with the Android 11 update, whenever that shows up.

It works with AT&T if you use an unlocked (XAA) phone.
AT&T only blocks it on the carrier version.
I have a Note 20 Ultra that was an AT&T carrier phone. I changed CSC to XAA and loaded U1 firmware and Call and Text on other devices is now available and working be tween my Tab S7 and my Note 20 Ultra.
Also, the calls do not get routed through Samsung. The link between the two devices is authenticated via Samsung, but the hand off is local (peer to peer) via your Wi-Fi connection.
Since you were able to get call and text on other devices working by changing firmware, did you loose the ability to make wifi calls? I have a S10 (AT&T carrier version) that I would like to keep the wifi-calling and also enable the call and text on other devices feature. Any suggestions?

Galaxy Tab S7 - Root and phone calls

Hi I am evaluating the purchase of a Galaxy Tab 7S but I absolutely need to be able to make / receive phone calls and messages. I read that it is only possible with root permissions but I didn't understand how. Once you have rooted what should I do? Do I have to install any specific app? Thanks a lot
By calls, do you mean voice calling or video calling?
For the former you'll need the Tab S7 5G and your carrier will have to allow it. Not all carriers enable tablets to make voice only calls. This applies to texting. Your carrier must allow it from a tablet; meaning your tablet uses its own number and is not paired to your phone's number. Otherwise, you'll have to use an app like Google Voice. I'm not sure rooting will bypass the carrier.
If you just want to do video calls, then the WiFi only version will work. No rooting needed. Of course you would need a WiFi connection for that to work.
Hi thanks for the reply. I am referring to the use of the tablet at 100% instead of the telephone, therefore receiving and sending calls via the Sim Card with the traditional number. What you say I already knew and unfortunately at the moment the Galaxy Tab factory setting only allows you to call with the Sim only if paired with a Samsung smartphone. In reality, the limitation is not imposed by the telephone operator (except in the USA) but by the customization of Android and it is not clear why there is this trend in tablets. However, I have read that through root you can bypass this limitation but I did not understand how.
I think I have reached the end of my research ... Unfortunately it is impossible because the modem is not GSM compatible and therefore not able to access the voice. Clearly this is a commercial speculative choice to push consumers to have 2 devices instead of just one ... The usual sadness!
Evidently, you can if you had the LTE version of the Tab S7 (which I didn't know existed) and are in Australia.

I can see your point about two devices. I'd rather use one number on two devices than two devices with two numbers.
The tab s7 t-875 model has phone functions, so you can stick your sim card in it and use it as your all in one device. It's available in Europe if that helps?

Do any carriers still allow texting on the S7+5G?

I bought this device ~2017 from Sprint for my elderly mother so she could stay connected with the family. One of the features was she could use it to text. She took to that like a fish in water, which made us happy. They did not have WiFi, so it was strictly cellular data. There was no voice, but that was not a problem. It had been working fine until...we got a Tmobile SIM in the mail. (Due to the merger of Sprint with TMobile.). This was supposed to be required due to the 3G retirement.
I installed the SIM. Everything seems to be fine. But then we notice the SMS stopped working. I called Sprint, they did some sort of reset and SMS started working. I went away in victory. But then an hour or so later we noticed SMS no longer worked. Skipping some steps, I took it to the store. We installed a new TMO SIM card. SMS worked again--for 5-15 min, then stopped. They did a warranty replaced of the tablet. Same thing. It first worked (send and receive texts) for <15 min, then failed. They would not allow me to go back to the Sprint SIM card.
I had the manager escalate this through their tech support. After a week or so, the answer came back: SMS is not supported on tablets.
This must be a policy. Certainly it can work. But it seems to be a restriction/problem on the carrier side. However I am not convinced it is really a policy and not just laziness.
What I am seeking from this forum is to learn the following:
A) Does anyone have SMS working on this device (SM-T978U).
B) If SMS works, what carrier do you have.
Alternately, I am looking for a work around that works seamlessly. Anything convoluted will not work for her. She also has an Alcatel GO flip 4. She now has WiFi.
You may want to look at an App like TextFree or Google Voice.
I can report that this was a carrier created problem. The explanation I received was that after the TMO Sprint merger, they pushed out PLMN's that allowed the devices to use the best available resource (TMO or Sprint), I am told. When the Sprint resources could no longer be accessed with the new TMO SIM card, the SMS no longer worked. If others had this problem, it may now silently be fixed. They need to push out an new PLMN and then "cancel" the location to forces the device to take the new PLMN. Works fine now.
My frustration is that the lower levels of tech support are really just customer service to help you use your phone. A rant on the whole experience is not worth anyone's time. For me, a chance encounter with a TMO employee in a local bar was required. Once I got to people with the appropriate level of technical knowledge, the problem was solved quickly.
The answer to the question in the title is 'YES'.
This is not a T-Mobile only issue. None of the US carriers allow LTE/5G tablets to text using SMS or RCS. I am not sure why. I had the LTE Tab S5e on Verizon and at no point could I text directly from the tablet using its number. I had to either use Google Voice or some other third-party app.
I now have the WiFi Tab S7 and the only way I can text is to pair it via Google Messages to my S22 Ultra or to use Google Voice.
The upside to using Google Messages is that I can use the same number on both devices. The only downside is occasionally I have to re-pair Google Messages.
I just bought a used T-Mobile Tab S7. I can sms with stock messaging app.
