i put in the sim card and the phone does not recognize it.
the screen says that there is no card inserted but there is.
the card works with my t-mobile phone and the phone is unlocked
do i need to download software for it because i have a favorite 5 plan?
i have a sony ericson s500i and it is unlocked. when i got it said it would work with any sim cards. but when i went to a t-mobile store they tried it out and said it didn't work, but i don't think the guy knew what he was doing. can any one help me i real don't want to get another phone
