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

 

[abakwa]

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

 

[Wilmerr]

"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

before i tried to change imei it worked whit TMN so it should't be hardware problem.
