New SIM card for existing device, plan, and number
I signed up for a data-only tablet plan but very stupidly broke the SIM card I received. A new one was supposed to be sent, but after 2 months of delays AT&T cancelled the order (so I’ve been paying for a service I don’t actually have). I bought a different AT&T SIM card elsewhere but have been unable to set it up:
1) At att.com/activate, when I select “activate my unlocked device,” it wants to set me up with a new plan. I already have a plan.
2) Also at att.com/activate, when I select “move my number to a different device,” it says “unable to transfer number.” It doesn’t ask whether it’s about my cell or tablet number.
3) At my account page, when I select “manage” for the tablet account, then “check if your device eligible [sic] to upgrade,” I now get an error message. I’ve tried this from the app and in a browser, again after quitting and restarting, etc.
4) When I first tried #3 a few hours ago and was able to enter my tablet’s IMEI number and the account’s billing ZIP code, I also got an error. This is the same tablet with the same IMEI that the plan was sent up for. I tried again several times and rechecked several times to make sure I had the numbers correct.
I’ve been Googling and searching AT&T support and can’t find an answer. In summary, I have a new and working SIM card for an existing data-only tablet plan with an existing phone number but can’t get everything working together. Any help would be greatly appreciated. Thank you.
