i have a working sim on my samsung gear s that can received calls and sms. i've noticed that every time i connect my gear s to my mobile via bluetooth. my line in the gear s becomes unavailable. when i call the number on my gears s, its prompting that the mobile has been switch off. but when i remove the bluetooth connection to my mobile the sim can be contact again.
is it normal?
is there any way that we can received calls and sms from the sim on gears s while connected to any mobile device via bluetooth?
thanks in advance

If you leave it set to Auto on/off, it only turns on the mobile network (voice and data) on when you have no Bluetooth connection.
I have a Dual SIM phone running Android 6.0.1 with two SIMs from two different operators. Once I enable mobile data on SIM No. 1 after some time I am unable to send and receive voice calls. To fix that I must turn the phone OFF / ON and it is then possible to make phone calls. But after some time the same problem is back. In case I deactivate mobile data on SIM No. 1 and activate it on SIM No. 2 the phone is working well and there is no any problem with incoming / outcoming calls on SIM No. 1 or SIM No. 2. Please help.
I have dual sim phone - SIM1 personal with calls/data and SIM2 for work with calls/data. The phone forces me to define one of the two SIM cards as default for data (aka browse the web). The problem is that if I define SIM1 as default data card, if I receive or make a call from SIM1 I can browse the web using data during the call, but if I make or receive a call with SIM2, during the call I can't browse the web (because it is dual standby). In settings menu I tried to change the default data SIM card during the call to SIM2 to continue browsing the web during the call with SIM2, but the phone tells me that" Can't change the default data card during the call". The problem is the same if I define the default data card to SIM2, so during a call with SIM1 I can't browse the web. So, resuming, the annoying thing is that I have a dual SIM phone and I have 2 SIM card both with calls and data plan, the phone forces me to define one of them as default to data, but during a call with the SIM that is not defined as default data card I can't use the web. If at least I could change, in settings menu, the default data SIM during the call it will solve my problem but the phone doesn't allow me to do that during the call. This is ridiculous!! The only chance is, if I need to access the internet during the call, to say "I will shut down this call to swipe my default SIM card to access the internet so I can talk to you while I can browse the web and read the email that you are refering to and call you again", this all in 2019, simply ridiculous.
Anyone can help me? I tried in some phones of some of my friends and it always happens the same (I tried in Asus Zenfone 3, Samsung S9, Xiaomi Mi9T). Please if anyone can help me because this behaviour makes no sense and makes dual sim completely useless nowadays.
We have a small local carrier in Southeast Oklahoma called Pine Cellular. They roam on ATT. When ATT recently turned off their old networks, it caused problems with roaming for Pine. They told my mother-in-law she needed a new phone with volte so I bought her the Oneplus Nord N200 5g as my son has that phone on T-Mobile. Insert her sim card and wifi calling and volte still don't work. Insert my T-Mobile sim and they work fine.
I took the phone to a Pine store and they lady even put in her personal sim which had allowed her to roam in Dallas (so volte was enabled) and it still wouldn't allow volte or wifi calling. She said Pine was in the process of updating their systems but she had no idea when it would start to work. They sold my father-in-law a cheap Alcatel and it works fine. I had been convinced it was something to do with the settings on my mother-in-laws sim until the sales rep tried her personal one.
Can anyone tell me what the heck was going on and why the phone wouldn't work on their network? I'm assuming it has something to do with Pine Cellular's internal settings but really WTF?
No one?
This was an unlocked phone bought from Amazon. It worked with the local Pine network, just Wi-Fi calling did not work and VoLTE did not work for roaming, but I could make and receive calls within the Pine Cellular service area. The old Pine Cellular network was GSM.
The Wi-Fi calling menu options appeared when I inserted my T-Mobile sim.
It sounds like you purchased a carrier variant (T-Mobile) version of the N200 (DE2118). Your phone model number is different than the unlocked generic version of the N200 (DE2117). AT&T operates its VoLTE network using whitelists. This means that AT&T will not use VoLTE with any other phone models than the ones they have approved on their list. Since AT&T has "shut down" 3G, phone calls can not be placed on their network without the use of VoLTE.
Only the unlocked generic version DE2117 is on their whitelist, as you can see here:
https://www.att.com/idpassets/images/support/pdf/Devices-Working-on-ATT-Network.pdf
You will not be able to use VoLTE on AT&T with that model of phone.
Wi-Fi Calling is similar to VoLTE, and operates under the same restrictions. (VoIP over Wi-Fi instead of over LTE cellular).
VoLTE is not a true standard. It relies on the implementation of custom VoIP software unique to each carrier and each device. Hence not a standard. The goverments have not forced carriers to standardize 4G like they did 3G, so the carriers have not. AT&T is using this chance to restrict access to their proprietary VoLTE implementation as a weapon to lock down phones to AT&T approved models with locked bootloaders and/or restricted software.
Many phones which support the VoLTE "standard" are not able to operate in VoLTE mode, neither with AT&T nor the other carriers. Even changing the system software on the phone can break these proprietary VoLTE implementations, as I have found personally.
It was the unlocked version. It did work on pine cellular. She could make and recieve calls on the phone network, just not roam because volte could not be enabled.

In that case, there are many steps to getting VoLTE working roaming on AT&T
1. The SIM card must have proper settings in it, sometimes requiring replacement of the SIM card.
2. IMS software must be installed on your phone (the proprietary VoLTE software made by your carrier). If you are running stock software, this is already done.
3. APN (IMS) settings must be correct. It seems your local carrier is still running 3G, and you do not need VoLTE there yet, so the pine cellular APN can be skipped.
Two APN entries are needed, one for data (carrier) and one for voice (IMS).
One will be named IMS with uniform settings, the other will be named after the carrier, with specific settings.
Settings -> Wi-Fi & Network -> SIM & Network settings -> Access Point Names -> APNs
Uniform IMS settings
VoLTE－Manually add the IMS APN - SUN Mobile
SUN Mobile
www.sunmobile.com.hk
The IMS APN is not the active "checked" one, but must be present in order for the voice (VoLTE) network to work on top of the data (LTE) network.
Each carrier has specific values that must be programmed. Sometimes Apple and Google will program these settings through their management controls for the major carriers, otherwise they must be inputted manually.

Thank you so much for writing all that out. i bet it's the APN settings. There was only the one for pine and putting the sim in another pine cellular phone had it working. I'm going to try one more time before I send it back. I'm not very confident that pine customer service knows that they are doing at this point.

I guess I'm going to send this phone back and buy something from Pine. Bought a new SIM card from them this morning and it still doesn't work. I now have data roaming on ATT but still no VoLTE or WIFI calling.
The Pine rep I talked to this morning was much better than the previous one and she said she had experienced this previously with a clients new phone. Pine was "old school" with some of their internal system.
I did notice they aren't selling any 5g phones yet so it's possible it's something with this being a 5G phone or maybe Android 11.
Hi. I need some help when using the S918B/DS with a combination of a standard sim (voice/text/data) and an e-sim (data only). The e-sim is intended for use in the US while traveling, bought using an e-sim app. I've setup the phone to use physical sim 1 for calls and sms and the e-sim for data. An APN is provided for the e-sim which must also be used. Roaming is also enabled.
Initially the setup works out with both sim/e-sim appearing in roaming mode and the e-sim also with 4G icon using T-Mobile. However, when I turn mobile data usage off (to save data and battery) then later re-engage data then I am not able to gain access to data. The icons show (both) of the carriers in roaming mode and that's it. The only way to reengage data seems to be: go to manual network selection for the e-sim, disconnect from current carrier (T-Mobile), select a different carrier such as Verizon (where there is no access granted) and then re-connect back with T-Mobile. This must be done with data enabled, otherwise I still don't get any data access. This works but also means that I need to have data/4G on all the time and can not use it only when needed. Is there's anything I'm doing wrong or there are some settings which can be tweaked to bring back data without disconnecting/reconnecting for the esim ?

If you want to save battery while travelling, instead of disabling data, you might want to set your physical sim to 3G/2G mode only (since it only for a call). And just turn of slot 2 (eSIM) when not used. Or try to disable VoLTE on the eSIM.
Or just airplane it altogether if you doesnt really intend to receive a call anyway. (I normally do it during travelling, i only use my phone to snap picture in certain area, using wifi when in resto, cafe or shopping area, and then turning off airplane only when i need to navigate using map)
