Anyone here using sim24 from 1&1 and have an Apple Watch? Please help me because I am at my wits end. I cannot activate the watch because I only ever see this message saying my 1&1 account is not authorised to activate Apple Watch. I have called them several times and they have been no help.

They insist that their service is compatible with Apple Watch. The first cs rep told me to simply scan the QR code for the eSIM, but that is not how apple watches are activated. The second cs rep told me to order the plan from Apple, which, no? Obviously not. The third rep told me to await an email from their technical team later that day. It’s been three days, no emails. If any of you have an Apple Watch active with sim24, PLEASE tell me how you did it. Thank you in advance.

P.S. the T-Mobile plan you see on my watch is from T-Mobile US, so it is not a valid long-term solution, as they will eventually cancel my service for excessive roaming, as I live in Germany now.
