Hi doczenith1, I get your log, and give it to our engineer to analyse, the engineer said that it seems that the format is not compatible, but US Mobile is a relatively large virtual supplier, and esim profile should be a standard format.
Do you get the esim profile from here? https://www.usmobile.com，I tried to buy this esim profile to the engineer for testing, but found that it could not be purchased. Could you help to provide an eSIM profile for testing?
