Hello Telekom-hilft team,

I need your help activating a Telekom eSIM for my daughter's Apple Watch SE 3 Cellular .

My situation:

• I ordered the Telekom contract on October 13, 2026.

• The eSIM activation letter with QR code was sent on October 20, 2026 and has now arrived.

• The Apple Watch should be used with its own phone number via Apple Family Setup (“Apple Watch for your children”).

• My iPhone uses a different mobile network provider (not Telekom).

• I am not aware of a corresponding Telekom phone number.

My problem:

In the Watch app on my iPhone, the "Configure Cellular" button is grayed out under "Cellular".

Additionally, a message appears stating that my Telekom.de account is not authorized to add a mobile plan to the Apple Watch.

Although I have already received the eSIM QR code, I cannot activate the eSIM on the Apple Watch.

My request:

1. Could you please check if my contract and eSIM are fully activated and if my plan supports Apple Watch Family Setup?

2. Could you please check whether the Apple Watch's EID needs to be manually linked to my existing eSIM profile or contract, and if so, do so?

3. Could you please tell me which phone number has been assigned to my contract?

4. Could you help me activate my Apple Watch independently of my iPhone's mobile carrier?

I found a similar, already solved case in your community:

I can gladly provide you with my customer number, order number and the EID of the Apple Watch via a secure, non-public channel.

Since I speak very little German, an answer in English would be very helpful to me.

Thank you for your support!

Kind regards
