GSM disconnects randomly

[mirh]

This seems to happen when I'm travelling, so I guess it may have something to do with switching towers.

A lot of people are having the same problem on XDA.

Edit

Removed log link due to personal info.

Hi, 

I'll forward this log link for you, but I've removed the public link to your log as logs contain possible personal information.

Hi @mirh

Can you please also pm me some links to the threads on XDA as this will help build a better picture of the issue.

I'm also experiencing this issue, but I get random disconnects and/or changes of carrier even when standing still. Here are some thing I also noticed and I hope we can get a fix soon:

- when I connect through national roaming I get a notification that it is disabled even though it's not and it disappears immediately.

- Sometimes when I'm connected to LTE+ I don't have any mobile data for short periods of time, but I think this issue is not related.

I live in poland and I'm using a virtual carrier called "mobile vikings" that uses the infrastructure of P4(commonly known as "Play") and allows roaming to t-mobile and "PLUS" but only on max H+ speeds. I tested my SIM on my previous phone - Xperia M5, and it's working just fine. I hope because it's happening to other ppl that it's a software issue that can be fixed in next updates. Also can anyone tell me how to provide a log, I'm more than willing help in identifying the issue.

Ok, I got it. I see that it contains personal info sooooo, if any mods/admins want to see it PM me.

I can confirm, that the phone has some connectivity issues.

In my case, in non-ideal network conditions both me and the other side of conversation experience drops in conversation, distorted sound and so on. Sometimes the call is droped prematurely

Bumping the thread, hope for a response. I've talked with my carrier and Sony and neither of them gives a solution. Unfortunately it seems to be a phone related problem since I tested my SIM card with 2 other Sony phones I had on hand (Xperia M and Xperia M5) and it works just fine. I'm still willing to provide my log, just let me so Sony can acknowledge it or at least tell us our phones are defective.

Same issue here. When I have no gsm connectivity and search for available networks, all my home networks (Telenor HU - 2g,3g,lte) show up as "Emergency calls only"

I'm on 51.1.A.4.173.

I'm from Hungary, and my carrier is Telekom. I'm having the same issue. In buildings or travelling my phone calls randomly disconnect and I can't make calls for few minutes. My signal indicator showing that I have signal.

I'm having exactly the same issue as you described below.

Did any of you find a solution for this one? I'm afraid I'll have to visit service center, but I'm curios whether they can fix it, especially without showing them the issue....
