Hi, I have a 24-month subscription with tmobile which lasts till August, 2023. On my tmobile app it says available renewal date is this April (4 months before the end date). However, I'd like to switch to another provider with a new phone subscription now. In this case, should I cancel/buy off my current tmobile subscription to port my number to another provider? Or can I still get a new subscription without cancel my current tmobile subscription? I have paid off all the device loan for your information.
