Is there any other governing body that defines eSIM and "EID" besides the GSM Association? Is GMSA standard for eUICC the only applicable standard for eSIM? Do cellular network providers / operators have their own standards defining implementation / use of eSIM? Stephen Charles Thompson (talk) 17:32, 16 September 2022 (UTC)
It may be appropriate to merging this content into the article eSIM. I see this article as stub quality due to short length. It was created to drill into GSM Association standards for eSIM. I am now looking into other standards for eSIM, if there are any. It may be that GSMA owns the term outright, unsure at this point. Stephen Charles Thompson (talk) 18:25, 16 September 2022 (UTC)
