I have to switch back to my old pre-paid phone for a short time. Will I be able to re-use the old SIM card or will I have to buy a new one?
I am koodoo prepaid ... had been using a Samsung 111 ... got a new 6S but it isn't working properly, so need to switch back to the 3 until the 6S gets fixed. The SIM cards are not interchangeable. It's been less than 90 days since the SIM card was used, so does that mean I should be able to switch back to it without issue?
