I have a prepaid T-Mobile SIM in my phone with 500+ prepaid minutes. I’m planning a vacation and would like to have the unlimited prepaid plan while I’m on the road.
Is there a way switch to the unlimited plan for one or two days while I'm on vacation, then switch back to the regular prepaid minutes without losing the minutes I have right now?
If not, could I get a second SIM and use it for a couple days with the unlimited prepaid plan? Would activating a second SIM on the same phone affect the prepaid minutes on my current SIM?
