Hello all,
I have had my unlocked H9493 Bordeaux Red XZ3 for about 6 months and it has worked fine on T-Mobile (Android 9, 52.0.A.3.202). Unfortunately, yesterday it randomly rebooted and after that it would no longer detect the SIM card and there is no wifi signal either; everything else on the phone works just fine. I keep getting the message "No SIM Card - No Service". I have rebooted several times with no luck. If I do leave it off for a while and turn it back on, sometimes I will get service & wifi for a little bit before the error starts all over again. If I leave the phone on with the error, it will reboot itself every few minutes.
I tried a different SIM card in the phone but still got the same issue. I put the original SIM card in another phone & it worked.
I scoured the web & found others having similar issues but none of their fixes worked (like using the *#*#... code and playing with the settings). I should mention that I did drop the phone a few hours before this started to happen but it was not that big a drop and I have a Ringke Fuxion-X case on it. There is no visual damage to the phone but perhaps I knocked the antennas loose ... ?
Before I do a factory reset, does anyone have any suggestions?
Thank you!
Hi @Xperia069, very sorry to hear about this. 
When you leave the phone on with the error and it restarts, can you remember if you have seen a text telling you that the SIM card has been removed and the device will restart? That is the normal behaviour for when the SIM card is removed, or your case, it's detected for a short while and then the device stops detecting it and thinks it has been removed from the device and that is why it's restarting.
What is very strange however is that Wi-Fi stops working as well and leads me to believe that it could have been some internal damage caused by the fall.
There isn't that much you can try I'm afraid prior to a factory reset / software repair as it's either a software error, or a hardware fault and we just have to narrow it down it to which one it is.
I would recommend that you do the software repair instead of a factory reset if you have access to a computer, as the software repair will reinstall the software in the device, instead of just removing personal information. Keep in mind that it's important that you create a backup before you start with the repair as all data on the internal storage will be deleted.
Should there be no change after performing the software repair, get in touch with your Local support team and they will assist you with having the device sent in to an authorized service centre so it can be examined.
Keep me posted!
