hi, this is a very common problem, what you need to do is either go to your network providers website and then see if the settings are on their that you can send to your phone these are free to get to your phone and you reciev them via text message then this updates all the settings that need changing and will solve your problem.

If the settings send button isnt on their web site then what you need to do is ring them up and ask them to send you the internet and media settings these will be sent via text message also, it will give you instructions to follow and then your phone will be working.

Let me know how you get on or if you need further assistance ok
