eSIM activation failing outside the U.S. after port-in to Xfinity Mobile

Hello,
I’m looking for advice regarding an eSIM activation issue with Xfinity Mobile.

I am currently temporarily living overseas (in South Korea) and will not be able to return to the United States for the next few months.
During this time, I recently ported my existing U.S. phone number to Xfinity Mobile.

The port-in itself appears to have completed successfully, but eSIM activation continues to fail.

Current situation

• Device: eSIM-compatible phone (iPhone)

• Location: outside the U.S.

• Status: number port-in completed / eSIM activation failed

I contacted Xfinity support and was told that eSIM activation might be possible overseas if Global Travel Pass is added to the line.

Based on that guidance, I attempted to enroll in Global Travel Pass and complete the required verification steps. However, the verification consistently failed, and as a result:

• Global Travel Pass could not be added

• eSIM activation still fails

At this point, I suspect that initial eSIM activation may require being physically within the U.S. network.
Since returning to the U.S. is not an option for me in the near term, I’m trying to determine whether there is any workable solution while remaining overseas.

Questions

1. Does Xfinity Mobile require initial eSIM activation to be completed within the U.S.?

2. Are there any confirmed cases where eSIM activation was successfully completed outside the U.S. with Global Travel Pass, or
   is there anything else I can try while overseas, given that the port-in has already been completed?

Any insights or shared experiences would be greatly appreciated.
Thank you.
