I'm trying to switch back to my Samsung Galaxy phone from my iPhone, but the website keeps saying my sim card is invalid no matter what I try. I'm certain I have been typing in the correct sim card number. How should I go about switching over my phone?

If you haven't switched back to your old SIM Card within 90 days then your old SIM Card will be unable to be used again and you will need to buy a new one.
