Sorry I not speak fluent English so excuse me for errors.Hello after much research I came across this forum.I have a sony ericsson t250i which i would like to unlock because it want to no longer accept any sim card. In addition the phone is in German so It still too complicated compréhension.At the startup a message came on screen and remains there as: Sim-Karte einlegen I 've not the German verb sorry but because with all the cards I inserted sims and it's the same message I deduced that he must be unlocked. I even accessed the secret menu of phone at the info service for the network,locks are closeds.Thanks to help me unlock! I count on you!
