Had an Lg phone before with a prepaid SIM card. I bought an iphone, bought a new SIM card(because Iphone SIM cards are smaller than Lg SIMs), I went on koodo self serve, went in "change SIM", entered the new SIM number for the iphone. Looked at the iphone, still said no service even after restarting it. I then realised that i had bought a PrePaid SIM for the Iphone (which isnt a prepaid phone). I cant go and switch the new PrePaid SIM at the moment so I decided to go back to my old phone for now. When I go in "change SIM" again and try to change it, it says SIM card already in use, but the Lg phone says the SIM card doesnt work. So now I have two phones, an Lg p500-h, prepaid, and an Iphone 4, that i cant use, and two SIM cards that wont work, PLEASE HELP ME WHAT DO I DO?
