Apple

I bought this device yesterday, I would like to say I'm not very good at English neither on old phones. I just thought it was a very cool tech product but when I turned on for the first time it said something like put a SIM card, so I did, I grabbed mine and it worked. I put my pin and then, nothing, it just let me make emergency calls. I read that 2g is not available on Europe and that may be the cause but I called myself and I received the call. I really want to avoid jailbreak and that kind of stuff just to keep it as original as I can. I may be wrong, maybe there's no other way but I would prefer keep like that.
