No signal after oreo update which was an automatic update. Anyone has the same problem?
Wifi is okay but I don't get any signal from my provider. Before the update it worked just fine.

I found the 'real problem', it's not that the phone doesn't receive signal but it's because the dual sims system doesn't work. I try with 1 simcard and it works well as usual but whenever I insert the second simcard suddenly the phone can't receive any signal.

Hi, I also got the same problem. My XA1 lost the mobile network connection after updating to Android 8.0. I reinitialized my smartphone, reset APN settings and reboot several times, but it dosen't work.
Though I did anything I can do, it doesn't solve the problem, but your post hinted to me. I just switched a SIM card to another slot, then it works!! Thaks for your post.

That just like my wife's phone, I only switched the simcards and it worked. Her phone is different brand though. For my phone it can only work if I only use 1 simcard, regardless the slot, both slots are fine, just can't use both slots in the same time, although one of the simcard is deactivated.

I contacted SONY support via chat. And they recommended ”FACTORY RESET”!
They suspected some apps might have conflict with mobile network abalability.
I did not have any other option.
After factory reset, my phone works well. Both SIM slot are OK.
There was no cost impact, but I'm not happy...
It is not easy for me with standard IT literacy.

I can no longer communicate after the update of the day before yesterday! (Wi-Fi is ok)
I did everything except initialization, but I did not recover.
I found this site a while ago and found out that there was someone of the same event, and immediately I changed the slot of SIM from 1 to 2, the communication was restored!
As I was able to use it as quickly as possible, it will be released from inconvenience, but what is the cause?
I hope improvement.

Yesterday I upgraded to Android Oreo 8 and my phone does not let me make calls tells me that there is no signal and I receive calls but I do not listen or listen to me, if I have Internet and I can also send SMS so it is not a sim problem because I already try with another sim from another company and the same thing happens.
Hola Ayer actualice a Android Oreo 8 y mi teléfono no me deja hacer llamadas me dice que no hay señal y recibo llamadas pero no escucho ni me escuchan, si tengo Internet y también puedo enviar SMS así que no es un problema de la sim porque ya intente con otra sim de otra compañía y pasa lo mismo. Gracias
