I noticed the other day that cellular wasn't really working, though I should have had plenty of data on my T-Mobile plan (using the eSIM in my iPad). Escalated it yesterday. Airplane mode on then off. It wouldn't show any cellular indications at the top of the screen (like an Wi-Fi model). Cycled power more than 1 time. Didn't work. I finally changed to the ATT SIM (with expired plan), and the ATT indicators showed up. Switched back, and it started working again on T-Mobile. So some hiccup WRT the eSIM?
