Wi-Fi calling - Huawei Mate 20 Pro Questions & Answers

Sim free, on Vodafone and I don't see any options for Wi-Fi calling?

Hi,
Once I've found in setting, suggestion settings: wi-fi calling, press that, set it up and then it's disappeared. Weird.
I'm also interesting where it's hide.
Also on Vodaphone single sim (even in Vodaphone told me it will be dual sim )

WiFi calling working fine on my Vodafone Mate 20 pro.

Hi
I changed the setting on version .108 where the option was under Settings > Wireless & Networks > WiFi Calling.
I cannot see this option now, but I do have a notification in my bar that shows me that WiFi calling is on.

What model number do you have?

From my understanding, Vodafone only supports their own phones for wifi calling and volte, unless its an apple i think, could be wrong here but i reckon sim free phone like mate 20 pro dont have that option??? Anyone else? Mine is a sim free with my contract sim only card inside and i dont see the option

I have lya-l09
My phone was bought directly from Vodafone and the WiFi Calling option is missing so hold out for the next update.

I have the LYA-L09 build .122 and i have had the same experience, wifi calling was available on initail startup from box but now no options in menu to enable.
[EDIT] I should mention the device is on Vodafone.

Has anyone got any info or an update?

Hi, im using a unlocked m20 Pro with my UK Vodafone contract sim. Try signing into your Vodafone account turn WiFi calling off, wait like 5 mins then turn it back on. That worked for me, im on the 122 firmware.

[Q] International Use: "No GSM/UTMS networks were found"

Hi Friends:
I bought used MoPho 4g to use overseas (stock 2.3.5 rooted). I popped in a VN sim but the phone tells me that no GSM/UTMS networks were found.
I switch to Global mode, but that still does not make the GSM detected.
The foreign sim works on another unlocked feature phone, so I know the account/SIM is good. When I go to the security settings to do a SIM lock (just to see), it says that no SIM is found.
In any case, I would think even if no SIM is found, that the phone should detect a GSM network, but it does not.
Thoughts?
You could have switched baseband. Try to reflash radio with RSD Lite. But first read, before flashing. Read twice or more.
Start in Photon Compendium thread and then 2.3.5 sv2 custom sbf thread.
Before playing with ROM flashing, confirm you have correct network mode:
Settings -> Wireless & Networks -> Mobile Networks -> Network Mode. Try choosing Any GSM/UMTS network and wait a couple of minutes. You may also try to choose Automatic.
I use it for gsm in the US and find that it sees the network better if I set it to automatic.

Yes, I set the network settings to both GSM and automatic. Both cannot detect the GSM network.
It looks like there are no other options, so I will look into flashing the baseband again.

have you checked that block roaming options aren't checked? happened to me a couple times. when you switch to GSM/UMTS mode, roaming block (block calls, data and sms) options activate by default.
Roaming guards are unchecked. Still can't get a gsm signal.
Thanks.

If you are (still) using Sprint, you need to call their international team to enable international roaming/usage (even if you are not using Sprint SIM).
This happened to me when I went to Germany. I had to call them from there (via VOIP) and I was able to use Simyo prepaid.

Hi Axelfox,
Were your questions answered and are you able to get on a GSM network yet? You can PM me if you like, I am currently in VN and using MobiFone SIM card with their unlimited 3G for $3/mo. Which SIM are you using?
Try this, go to the Google Play market and download an APN manager such as:
Offline SIM APN Database
Tweakker APN Internet MMS
APN Manager Pro
-GP
Thanks to all. I was not able to call Sprint to activate international roaming, but that is good to know. It was my understanding that it was internationally unlocked out of the box and I could just pop in the sim.

Debranding AT&T Lumia 920

Hi,
is there any way to put a different ROM on an AT&T Lumia 920.
I intend to use it overseas but I need the Internet Sharing option enabled (wifi hotspot) and as far as I know AT&T and Rogers has it blocked by default.
Any help on this?
Thanks

But does it enable it to any carrier?
Because I have read that this app has predefined APNs for some selected carriers, and I'm planning to use it on carriers that may not be listed on it.
Actually, it uses the APN's from the SIM and it works really good.

Are you asking if a ROM flash will unlock your phone so that you can use a different carrier's SIM? You'd need to do that first. Then you can use Access Point.
Are you saying that the access point app enables tethering on AT&T without a tethering plan???
If so, I suppose anyone can sideload this app and start tethering on AT&T without flashing new ROMs?
Where is Access Point App
??? Can't find it

I can't either, its region/ROM specific in the Nokia store apparently. You would need to sideload if anything or else flash a different ROM to get the app.
Can we sideload apps on WP8?
I didn't know this app was not available for all regions.
Try with your own risk for you can't uninstall this. The only way to remove this is through factory reset.

Hmm, does anyone know if you select AT&T 3G, does that then disable LTE? Is there any benefit to have one of those AP's selected over the others?

I suspect this:
When a carrier has LTE aside from GSM it has to have two different APNs since there are different core networks.
That's why you have to have at least 2 APN configured, one for LTE ( the data will go thru LTE data core) and when the phone is out of LTE coverage, in 3G/2G GSM it uses the other APN configured for GSM data.
you can confirm this by just leaving only one APN configured and try to use data on LTE and 3G HSPA, only one should work depending on which APN you configured.

I see, so what you are saying is if I select 3G, it should automatically switch to one of the LTE ones. But if I select 3G and delete the other two, it will only work on 3G?
I would test that theory, but my device will not let me delete or modify the built in APNs (guessing it's an ATT restriction).
Thanks!

Once installed, it will be on Settings. As far as I know, you need an unlocked device to make internet sharing works. (I could be wrong)
APN wise, it should automatically detect the settings of your carrier from the SIM. I never really messed with it as much. I was just curious about the app hehe.
If you guys need more help, go to wpcentral's forums and search for access point. There are tons of threads about it.
well guys, I'm onboard. I just ordered my unlocked AT&T lumia 920 and as soon as it arrives I will install this app.
Thanks everyone for their sharing.
Installed the app and I'm still not able to enable Internet Sharing. In Access Point there are two LTE options and one 3G. For both LTE options attempting to enable LTE gives the message about going to the AT&T website.
With the 3G option it simply saying "Internet sharing isn't currently available".
Same to me

4g+ on xiaomi mi a3 EUR?

hello is it possible to have the 4g + on the European version of xiaomi mi a3? because I only capture the 4g
I have the same question.
For turn on the volte write this code in dialer app *#*#86583#*#*
It's just the Google One UI, you are getting 4G+ don't worry.
The Google One UI tries to simply everything by not bombarding you with + or VoLTE signs etc, however they can be enabled using service settings if you really want to take up preacious space on your notification bar.
You can confirm what signal you're getting and the speed with free apps from the Play store.
after the October and November update, the problem of lack LTE+/4G+/Carrier Aggregation is still not resolved.
anyone know if xiaomi is working on a patch?
I have EU version.
On my simcard LTE+ works with Mi 8 lite
What's 4G+/LTE+ and how to check if I have it?
Is it the enhanced LTE mode (voice calls over data)?
4G+/LTE+ is implementation of LTE-A standard, involves carrier aggregation, 4x4 MIMO, etc. It's more about data rather than voice over LTE. I have 4G+ in my area while VoLTE is disabled.

Probably Mi A3 just misses the specific carrier profile and uses a generic profile not 100% compatible with that specific carrier. I have another carrier profile issue, when I enable VoLTE I cannot send SMS. Because the generic carrier profile assumes SMS over IP/IMS when VoLTE enabled, while my carrier uses some perverted setup where SMS still sent over signalling. I doubt Xiaomi will rush adding/updating carrier profiles. If you have root you can change carrier profile with QPST PDC tool.
it is possible to change the carrier profile without root??
If you mean changing carrier profile using that Qualcomm PDC tool then nope. You need set "setprop sys.usb.config diag,serial_cdev,rmnet,adb", but it's impossible w/o root since Android 8.
I rooted and tried to enable interband carrier aggregation using this guide. Everything seemed to work fine, but I still don't get 4G+. Anybody was successful with this, maybe following a different procedure?

CA works great using B3, B7, and B28, didn't modify anything, using it as it came from the box; 3CA supported, tested using • NetMonster, just a reminder, some carriers are known to not be able to trigger device status bar icon (4G+/VoLTE) even though there's support; I recommend using the app above, if you see LTE-A, there's 4G+ connection.

Seems to work for me.
It also works for me, but only when wifi is connected. When I disable wifi, Netmonster says I'm connected to only one band, I think that's why I never see the 4G+ sign in the status bar.

I never see 4G+ just 4G.
Xiaomi Mi A3 support only Contiguous CA: https://cacombos.com/device?model=M1906F9SH - so thats why you maybe don't see 4G+ in your network because most of network do Non-Contiguous CA.
before the update to Android 10, the speed was very good with 4G +, but since only 4G appears, the speed dropped considerably
I'm from Mexico, with Telcel, Mi A3 Global
I leave images with the speeds
Has anyone with the European version for Android 10 managed to run operator aggregation?
hi i have same problem with original rom 4g+ ok but with pixel experience rom i have lost 4g+ blocked in 4g

Question 5G network - post screenshot

Hello,
I have a Pixel 6 phone, Japanese version, under the sim card settings 5G network selection is not available, I am not sure if its my phone or some restrictions in place by Google, Pixel 6 is not officially launched but pixel 6a is in my country, can someone post the screenshot of your phone, how the 5G network selection option looks like?
If you're not seeing "5G recommended" under the preferred network type, you may have an old SIM that doesn't have 5G support. Yes, this is a thing.
Ask for a new SIM. If you still don't see 5G as an option your carrier may need to add the IMEI to their whitelist of approved phones.

Earlier I thought that firmware doesn't support 5g because phone is not officially launched in my country.

My bad, it seems to be software issue, yesterday my friend also couldn't get 5g on his iPhone 13 pro, not sure if Google has plans of releasing software updates...

Before that it was right under VoLTE
The problem is no VoLTE logo, just Wifi-Call Logo (Telefonica/o2) but it's working, when I call someone I stay on 4G network.
That's how it needs to look like but in Asia they get just a HD logo
I know from xiaomi.eu o2 don't support VoLTE logo/icon on Xiaomi device's (with eu firmware you can see it).
What's the problem with Samsung?

VOLTE logo appears in three conditions
1. You are in a supported & covered area
2. Sometimes you have to buy new SIM card
3. Your device is added on your network supplier support list
It may appear in settings but your network hasn't added it on its support list
In my situation i was have to activate VoLTE and Wifi Calling sending the code to the carrier. PL here. Now i have icon VoLTE and wifi calling when available.
i think is carrier dependent -
I am on vodafoneUK and never had a volte icon despite using one
i get the wifi calling one tho

I'm having 2 sim cards and both support VoLTE , on my S22 ultra both are showing VoLTE icon but when transferring them to S23 only Sim 1 is showing VoLTE so S23U is still not supported on my second sim network , give it some time or call your service provider customer service
O2 UK since S20 Ultra, no VoLTE icon, only VoWiFi icon, second sim Smarty (3UK), no VoLTE icon, only VoWiFi icon.
When I turn on WiFi calling, you cannot use Bixby text calling
I just have a phone icon for WiFi calling
Is wifi calling a telcom service related feature, or is it enabled for certain regions. If so, which CSC would be best for me to flash to? I am using Indonesia's XID.

Ah okay thanks?
The easiest way to see if VoLTE is working:
Make a call whilst mobile data is on.
Does mobile data drop to 3G/H/G/E?
No? Cool you have working VoLTE.
If you answered yes. You do not. Waiting for provider or for Samsung.
Just because you don't have the logo doesn't mean you don't have it.
