Hi guys i wonder if some1 can help me.

I have just baught a new W850i on Three , got it unlocked but now my O2 sim is not working in it. it keeps giving an error insert USIM i guess its because the sim is 4 years old and is a GSM sim.

* the sim works fine in a K800i.

any help will be apriciated

thanx kas

Try asking o2 for a new 3G SIM? Same thing happened to me when I got my V600i, Needed a new SIM as my old one was too outdated.

USIM i think is a 3g or three sim card as 3 is the only network to have their phones say 'U'sim, if it says insert correct USIM thne it hasnt been unnlocked if it just says insert USIM then i dont think it is recognising it
