I need a little help here I just got the P7 L10 and I put my T-Mobile SIM but most of the time when I try to place a call after dialing I get a message SIGNAL IS UNSTABLE my calls fail and whoever tries to call me will sometimes get my voicemail without my phone ever ringing this happens about 80% of the time.

I'm having issues with calls and texts on T-mobile since this morning. Whenever I place a call the phone sometimes takes 10 seconds to ring, rarely it'll go straight to voicemail, and more often the call won't go through at all, the call will just drop.
If I myself end the call I lose any sort of connection, no 2g no 3g no LTE; I checked settings/about/network and Cellular Network Type gets stuck on UMTS. When this happens I can't call nor can I send messages, the redundant fix that I have to do to fix LTE and get messages working again is to go into: settings/mobile data/network operators and register automatically again, this always gives me LTE and messaging back, and sometimes calls, sometimes.
On the other end, when people call me, I noticed that the phone will go into 4g or H which is the same thing I believe. However, calls don't come through, it either goes straight to voicemail or it'll ring once or twice then go straight to voicemail. Also when it rings on their end, I can't hear it on my end, phone is silent.
This has happened on 4 roms Eragon, NusenSeven, Stock GP Edition and Insert Coin,
The phone is rooted and s-off
HBoot: 161
7.19.401.2
If anyone has the same issue or know a fix, please let me know, it's getting a tad bit annoying.
Hoping It could be the sim card, Thank you, much appreciated
Edit: Apparently T-Mobile was having issues in my area. Surprised it was out for 3 days.
I have brand new phone bought in India with default settings and OS. On Jio sim when phone is lying idle for few minutes it stops receive calls. Caller gets message that phone is offline. The moment I pick up phone I can see missed calls. When screen is on there is no problem in calling or sending calls. It seems phone goes in deep sleep when lying idle and cellular service gets stopped. Please advice.

Hello,
I need help diagnosing whats going on with my HTC desire 626s. The phone is unlocked, rooted, and has TWRP installed.
Problem: I can't make calls while I'm at my home. I have excellent signal strength being I'm within visual range of the cell tower.
The phone has always worked at my home in the past then about a two months ago I wasn't able to make or receive calls. The internet works fine, and texting works fine. When I try to make a call nothing happens then there is a beep and the phone says call ended. This is an unlocked phone on att go phone service. After this issue started I called att and created several trouble tickets and every time they state the service is working fine. When the phone was working normally during calls the 4gLTE indicator would swap to 4G and make calls on an hspa network. After att was unable to fix the issue I bought a new sim card. For a month I was able to make calls just fine but then on Halloween night the problem came back. I highly suspect that someone is blocking my ability to make and receive calls. I need help from someone that knows more than me on how to diagnose exactly why the calls are not goign thru. I really need help. I have swapped the sim card into a new phone was able to make a call or two then the service was again unable to make or receive calls. I just need help on how to diagnose exactly whats stopping the calls from going thru. Thank you.
PS. Another att go phone works in the same location that mine does not so it is not a issue of the walls blocking the signal.
I am getting calls that go straight to voicemail. This does not happen all the time, but when it does there is no call log, just a voicemail notification. Searching the web and support calls to T-Mobile seems to indicate that it is because the Mate 20 Lite does not support VoLTE, even though the phone has the band support. When a call comes in, T-Mobile will try and drop the call from LTE to 2G/3G, fail and then send the call straight to VM. Cannot find a solution and it seems there are many people having this issue across many different brands of unlocked phones on the T-Mobile network.
Here is the odd part and why I think it might be the phone. I am getting insane battery life on the Mate 20 Lite. I charged the phone to 100%last night, went to bed and 8 hours later it was still at 100%. Last night I missed an important call that went straight to VM. No forwarders, call blocks, airplane mode etc. I also noticed that these straight to VM calls happen when the phone has been sitting/immobile for a while. Like the aggressive battery management is killing some service. This does not happen with a Xiaomi A2 that my wife is using.
BTW, I am connecting to band LTE band 4 and get near 40Mbps down when testing, so I assume I am getting 4G LTE.
The phone is still within the return window and if I cannot solve this, I have to send it back.
Anyone have a solution?
No solution. I have a similar problem where I live there is nearly no cellular reception and the only way to get calls is to be connected to WiFi which activates VoLTE / Voice over WIFI. Huawei Mate 20 Lite does not do it though. Why not?
i am looking into the dropped call issue on t-moble/metro. i do believe when the phones power saving kicks in after being idle it causes the phone calls to be dropped. i do not know how we could fix that, but if there is a way to get around that the help would be appreciated. and/or would entering manually the metro APN help at all as i am on metro
