Removed iphone SE from Ting account a few months ago. When it was on my account it had its own Ting SIM card. Tried to add it back onto the account but got "This SIM card is not compatible with Ting"...even though it is a Ting SIM card.
Ultimately, I wish to move my phone number to the iphone SE that I am trying to put onto my account. When I try to put MY Ting SIM (not same as above SIM) in, it says "This SIM is already in use with Ting" and to go to my account.
