I have an old Telecom SIM that was used in a T-Stick. I want to use it in a phone with a micro SIM as backup SIM. I bought a SIM cutter tool but unfortunately after it cut the SIM the SIM no longer works. I know with 2Degrees and Skinny you can buy a replacement SIM and change the number from an old SIM onine. Can you do this with a Spark SIM?? Yes I would take it to a Spark store to change it but there are non close to where I live.
