Hi all,
I have a problem with my Xperia X10 (i)
I purchased it new, unlocked. It worked fine for a week or so, then I switched to another network operator that works on AWS/1700 Mhz/BandIV. The phone is supposed to work with this frequency as far as I understand. Now the issue I have is every time I loose the network signal (I park my car in the underground parking) & when I come back to the place where there is network signal my phone does not get the network back. I try to connect manually and I get the message: " your sim card does not allow a connection to this network". When I try to connect automatically it says "Registered on network" but there is no signal.
I changed 3 sim cards so far. Still the same. When I put the sim card in another phone that also works with AWS/1700 Mhz/BandIV the other phone manages to find the signal. I put back the sim card in my Xperia, it works fine until for some reason I have no signal and the circle continues.. I love my phone, I want it to work, with this provider.
I am very annoyed. The network provider doesn't know what could it be, they blame the phone. But the phone works with other providers with no problem so I assume it is something else.
I did a factory settings restore, I checked for updates..

I want to fix it, this issue drives me crazy and I don't want to let it go, I want to FIX it.
PLEASEEEEEEEEEEEEEEEEE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
