iPad Setting for "Add a New Plan" not working
I work on the premise that "once it worked perfectly but now it doesn't" and I would love to be able to correct this as I do use this setting at least three times a year to cover me when I travel. I am working with AT&T but so far no answers.
For years now I have been able to enter Settings>Cellular Data> "Add a New Plan" for my AT&T account and easily add an International Plan before departure or while traveling and needing additional data. This setting no longer works. Instead I get the message ""The connection to the server was lost. Please try again later."
I returned to the US on Sept 30 and I updated my iPad to IOS 12 on I believe Oct. 2nd or 3rd. I do not recall when I noticed the connection failure but I am fairly sure it was before the update to IOS 12. I was able to purchase a plan in August, "Worldwide Data 1GB for 30 days Int'l 271.3 MB used 09/05/2018 to 10/05/2018". So it worked fine then.
This setting no longer works. Is anyone having similar problems or have suggestions?
I have rebooted the iPad, the SIM is active, my account is active and can be seen using myAT&T online. I have tried the connection both on wifi and with the cellular and I get the same message. It is the Setting on the iPad under Cellular Data that no longer connects.
Thank you for any assistance,
Pat
