As anyone had problems with LG7100 on the Orange network. I bought my phone in may this year and since that time it as been back to LG 6 times as it keeps turning off, The pcb as been replaced twice the battery pack once but it stll keeps turning off. On the 3rd december i tried a new Orange sim card but no joy. LG say its the sim card thats at fault and Orange say its the phone. can anybody help ?

Try with other network operators SIM card?
if te problem persists, it should be the phone.

one way to tes is the "ON' the phone with the SIM.
it should turn to the "SOS" thing..c if it could be power off...

hope this helps...
