No service after Android 8.0 Oreo update

[OtakuNTT]

Hi all,

Prior to the update I had full service including voice, Samsung and data. After updating my Sony XA1 Ultra to Android 8.0 everything stopped working.

My telecom provider NTT Docomo is clueless and isn't of much help.

I have tried everything from airplane mode toggling, manual telecom selection and a full reset with Sony xperia companion.

Is anyone aware of this issue or knows how to get the back my telecom service?

Phone info:

Hi
Maybe it's because your SIM get demagnetized, or it's old and with old bands that aren't compatible with Oreo.
Try to buy a newer one from your provider's shop, should cost about 5€/$.
I hope It was helpful :highfive:

I posted my "solution" there. In case your phone is also a dual sim, it might fix your problem for a while.
