[funkymonkey24]

hi all i hope you can help me i have a wildfire which was originally on 3 but is unlocked, i had a different sim in there, last night i went to the shop and brought a 3 sim, put it in my phone and the signal is sooo poor my mate called and it kept disconnecting us! Iv tried and failed to contact 3 there helpline is appalling. Iv put my normal sim back in now but will like to swap it over again on occasions to speak to my friend. is there anyone with some answers ? thanks x
