I was not planning on activating the cellular functionality but figured why not. Now it seems like AT&T does not know how to handle. I bought the extra line for it and did go through activating, but it didn't show up after a day. Then I chatted with someone and tried to activate it again, then throughout that process my SIM card was disconnected from my iPhone X. Got a new SIM card from store. Rep from store could not figure out why it was not activating either, even though on the watch it listed a plan and said it was not available... then I went to a different AT&T store today and the guy told me they are having problems activating S4 because of the eSIM inside... I called AT&T and they opened up a ticket based off the information I gave. The woman on the phone thinks its either my account (which is in good standing) or the AT&T app that is causing this issue, based on the notes they have of the error. This is really frustrating and reminds me of the debacle a lot of people were having with activations last year of the S3. Any advice?
