signal problem

I don't have signal when I restarting phone signal comes for few minutes and gone again I try sim on other phone and worked well

[Thommo]

Has the phone been blocked from working on that network? Is the phone an import?

Can you check if the same problem occurs in safe mode?

Hi ffffff,

Discussion Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines

This could still be related to the SIM card, I suggest that you use a different SIM in the Xperia device first, as putting your current SIM in another phone does not actually clarify that it is the SIM or not, as the SIM may work fine in other devices.

I'm also having the signal problem! Are you on three by any chance?
