Previously, I had my kids apple watch on AT&T. I am trying to switch to US Mobile on the standalone plan and we're having the most difficult time. Probably spent atleast 3-4 hours everyday for the last week with US mobile, Apple Support, AT&T.
We've cancelled the line with AT&T, escalated to level 2 technical support, and have asked to confirm that they've released the watch IMEI and EID from their provisioning services. Which they say they have.
Everytime we try to activate the watch, it fails to configure cellular. What I've noticed is that when we try to setup cellular and I leave the screen it shows that it is still trying to connect to AT&T for cellular.
We are using a different phone that has Visible as the primary esim. We also have a temporary US Mobile esim on the iphone we're trying to activate it. We've gone through the steps of disabling the visible esim, adding the temporary US mobile esim, disabling all esims, restarting all devices, new phone numbers, etc...
Just recently Apple support says US Mobile is not a supported carrier but we know it works because we have friends who have their kids watches on US Mobile (Apple Watch SE 2).
Does anyone have any experience or suggestions?
