no signal xperia 10 11

[Willtt]

I have been using a new Sony Xperia 10ii from O2 for a few days. The signal in the house is almost non existent, and patchy outdoors even near a transmitter. My previous phone (a motorola ) had a good signal in and out of the house, as does an iphone 5s. I have contacted O2 but they have not come up with a solution. As I am still within the return period I am thinking of sending it back as faulty, which would be a pity because it has some decent features, luckily including wifi calling which is the only way to call from the house.

I have tried resetting and restarting, turning off wifi etc, but nothing seems to make any difference.

Any suggestions?

Take thee sim out, clean and reinsert. Reboot the phone

Edited to add, if nothing improves, you have 14 days to change your mind about the phone.
