hi

new on here so be patient with me.

i just been given a 8900 curve of my brother, it was on orange,
i have unlocked it.

i now want to use it on o2 pay as you go?

i have tried a number of sims(o2, tmobile, virgin) all appear to work ok, carrier name comes up on screen etc, but when you make a call it comes up with the message "call failure".
also it wont send sms.

any help would be much apprecaited

thanks
