What should i do?

anyone
please help me

your's phone no have signal try to replace the PFO and the antena sw

the 2 provider is in same frecv (900 or 1800)? ist posibly your ant sw not work????

change PA .. it will work

I know that this a late answer, but... didn't ANYONE thought that the phone is SIM-locked?!?!? It's obvious! Exclamation Mark before the provider means "no acces to this network"!

i tried to change imei but i can't

what should i do

Change PA, if it does not work, proceed to change ant sw. its common with siemens

"PA"?
"ant sw"?

explain please

thanks in advance

Sorry, i meant PF or antenna switch. You can check the diagram of the fone using serch button. Usually u should start by changing the PF, if the network is not stable, then u change the antenna switch. You shall need the hotair pump
