Hoping someone on here can help me out.
I ported my t-mobile no. over to Talkmobile on the fifth. Sim card arrived today and I've bumped it into My samsung Galaxy. However, there is a sim card icon with an exclamation mark in the top right hand corner. Anyone know what this means? I can't send texts etc so I'm guessing it's to do with a sim not recognisable or something?
Also, my galaxy is asking for a network code. I thought the phone is network unlocked when your previous contract runs out?
