My SIM card doesn't work and it says "SIM not provisioned" on the phone even if number still says it's active on my fello account. Furthermore, my unused surfing data also dissapears from my account. So I can't use my number to make/ receive calls, browsing on the internet and everything. This is so dissapointing because all Fello could offer was sending me a new SIM card which still means that I won't be able to use my number until the new SIM card arrives.
