So, I bought an iPhone 4 from eBay, inserted O2 micro sim card. It says "o2" at the top but there are no signal bars. I can connect to wifi and make emergency calls. However I cannot make or receive calls or sms.
What is the problem here and how can I fix it?
I've been to the apple store and the O2 store but they keep giving me conflicting information and sending me elsewhere. First they said it was locked to a different network, then that I just had to wait for activation, then that it was bricked - I just don't believe they know what they are talking about.
How can I check if the imei is blocked, perhaps that is the problem? One website told me it was not blocked but I'm not sure how reliable that is.
Any help would be greatly appreciated.
Thank you beautiful people!
