Is it my phone or O2?

[Anonymous]

It's an annoying problem that I can not tell is happening. Some of my friends phones can not text me, they either can't send it at all or it does send and I have about 50/50 chance of receiving it sometimes hours or days late.

Anyone else had this? is it my SIM, my phone or O2?

do you have signal in your area, check the o2 status checker to see if there arent any fault in your area. if that isnt the case. go to your local o2 store, tell them what is happening, ask for a new sim & see if that helps.

ps just also try a hard reset on your phone or restore it to the original factory settings
