Thank for this thread. My wife got the Xs Max. I've been trying to get t-mobile to swich it to e-sim. I tried Twitter & iMessage several times, they're not willing to do it. I went to the store, got a rep who's willing to try eventhough he think it will not work. He was surprised that the system accept the eid number . I do have to wait 30-45 mins to continue on the next step though.
