It has been a while since I don't use my prepaid phone. I'm abroad and I will come back to USA next month. I don't have access to the SIM CARD. Although I have all number printed on the card (Puk, Pin, etc.). How do I check if my number still valid?

        We won’t be able to see for sure here on a user forum but if it has been 90 days since you last added money to your account, the chances of it still being active are slim. If you want to check for sure, you can Contact Us and our customer care team can look up the account to see if it is still available to be used when you return.
