Hi

Very new to this forum, so I hope I can get some good answers!

Currently using an unlocked V800 (Vodafone) in the US with a T-Mobile PAYG SIM. Phone was working fine, but now exhibits peculiar behaviour.....when the handset is open, signal strength shows 5 full bars. However, close the handset, and the signal strength rapidly decays to 1 bar, and sometimes "No access to network" or "Emergency calls only." Worryingly, when I went back to the UK last week for a business trip, this behaviour seemed to happen with the Voda3G SIM card too.

Any thoughts? I've got RD1 (?) firmware. Should I try and upgrade it (even though I think I left the cable in the UK.... ).

Or....does anyone know a decent SE dealership in Manhattan that could give it a once-over?

Cheers......Temanga.

Keep your phone open and not closed:-). Kidding aside, i think a firmware upgrade will sort your problems. Worth giving it a try. This message was posted from a WAP device

Sounds a bit like a possible hardware problem too, the way the signal disappears when you close the phone, I wonder if something like a data ribbon that carries info from one part of the phone to the other has come loose or something?

OK I know exactly what you are talking about. The EXACT SAME THING has happened to me and it is indeed a HARDWARE problem.

Please refer to these threads for my experiences with this issue:

The difference is marginal i think maybe a bit better in 2G and 900MHz regions. This message was posted from a Z1010
