I need to read a SIM card on an LG model lm-x220mb, which is microsdhc. I know that SIM cards do not typically hold information; however, I do need to see if this one has been backed up with contacts. I tried inserting it into my iPhone, but it did not work (said it was not the same carrier, or something like that). How can I see what is on this SIM card? I called around to a couple local repair shops - none could help me. Any suggestions?
