I was given a Samung S4 that was locked to O2 by a friend. Recently acquired the unlocking code from the network provider than then made my SIM card (from 3 Mobile) valid and it worked fine... for about half an hour. Now the phone is saying to me that there is no network provided, and every time I go to Settings to select 3 as the network provider it takes forever and then it says it's unable to connect and to try again later. I don't understand what's going on as it sent a couple of messages before and now seems to have suddenly rejected what should be a valid network. Have tried all the methods I've come across on various webpages and nothing seems to be working.
Anybody know how I'm able to be able to get my network back please?
