Sony X Compact no sim card error

Hello,
For about 1-2 months now my Sony Xperia X Compact very often doesn't recognize a SIM card. Only reboot can help (sometimes after reboot it works well, sometimes network appers for only a few seconds and SIM-card disappears again. It seems (but I'm not completely sure) like quick change of network preferred (GSMonly-WCDMAonly - WCDMA/GSM - LTE/WCDMA/GSM) after rebbot makes it more likely for phone to recognize card for some time longer).
It happens pretty randomly, but is much more likely to happen in areas with bad mobile signal (at work, in the country(no LTE, almost no WCDMA, some areas with no signal at all(cold stores)) after about an hour (not immediately!) phone stops to recognize sim-card and after that I just keep rebooting it with a small chance of getting it to work for 10-20 mins (but more likely for 30s), while in the city it usually works much better, sim-card disappears only few times a day). 
Even if phone does not detect SIM-card in test menu *#*#4636#*#*  signal data is reading (for example -105dBm 35 asu as I'm writing this)
Resetting connection settings didn't help.
Tweaking *#*#4636#*#* settings (as described here) doesn't help.
Factory reset (ads well as Software repair using Xperia Companion) didn't help.
Putting three layers of duck tape over back of a card, to make it thicker for a better contact (as suggested to me at phone repair shop) didn't help.
Phone temperature doesn't seem to play any role (it happens in the pocket as well as on the table).
I don't remember actual dates, but I think the problem started in the last decade of October, while, as I have found out, last release of firmware(34.4.A.2.118) was relesed September, 25 (I guess phone upgraded in October), so could it be a problem with the update?
Where to get the previous version of firmware(34.4.A.2.107 or eallier) for my region(Ukraine)? (or is it okay to install version for a different region?)
Or will it help and is it possible to change the radio module firmware?

 

Sony Xperia X Compact F5321

Android 8.0.0

Firmware version: 34.4.A.2.118

Current radio module version: 8976-8976.gen.prodQ-00017-39

P.S. I know I'm not the first owner of Sony Xperia with this problem, so I hope the company is going to fix it with the new update or at least give some other solution.
I really liked my compact phone, but with such a huge problem it's not a phone at all. They said me at the repair shop, that connection problems are very common with Xperia devices. Not the best  reputation for a brand to have. 
P.S.2. I had the problems with mobile connection from the start: it took very long time (more than a minute) for the phone to recognize the network, after it lost it, while other phones do it in seconds.

Re: Sony X Compact no sim card error

Hi,

 

the same problem here.

Today it hapenned twice for me. My Xcompact starting to be useless.

It's a shame but after two xperia compacts I will have to look somewhere else.

Nonexistent sw support for OS after 2 years is another deal breaker for me.

Re: Sony X Compact no sim card error

Same problem here, can't solve it either. I'm on my third Sony phone in six years. I have a had an Xperia V, Z3 Compact and X Compact. I have seen tons of problems magically pop up. Too bad it's hard to find a decent compact smartphone. I guess Sony is aware of this. Still, it's bye-bye Sony for me. Even if I would still trust this brand, the newest compact phone (ZX2) has got too little unique selling points. (Even compact is getting bigger, no more fingerprint scanner in power button,...)

Re: Sony X Compact no sim card error

Lol, started happening to me few days ago. It was a reliable phone but of course something must have screwed up with with it and "sorry dear customer you need a new phone". Usually after restarting my phone it would recognise the SIM card, but there's a different weird aspect to it. After like 10 minutes the phone "sees" the SIM card, but I can't connect to any network nor I can change the network preferences... I would love a SONY moderator to answer on this topic and tell us if there's anything we can do, maybe it's software fault? Maybe they can patch it? It would be a shame if it were the components failing because I really love this phone, indestructible and still performs smoothly.

@Jacob2137

Same exact same thing is happening to me as of yesterday. Triangle symbol/no bars. Restarting the phone shows no sim card until ~15min later it chanes to no signal. Overnighted a new sim card and the new one is doing the same thing.

 

Guess it's time for a new phone.

I actually can't dial anything successfully. I immediatly get a pop-up telling me to enable wifi calling. I can't find this setting anywhere, and some Googling taught me this is probably a feature not available in my country. Since my phone never recognizes my sim card anymore, I can't get past this pop-up.
