Cellular Data not working -- odd looking Cellular data icon
Yesterday, I moved my kids' LG Flip-Phones over to a couple of used (but wiped clean) iPhone 8s.
Today, I discovered that while:
- Cellular Data is On (in Settings->Celluar->Cellular Data)
- The AT&T page shows those phones as having Data active
... neither of the two iPhones actually are getting any Cellular Data (iMessages don't work except on WiFi, Browsing Podcasts says "not connected" except when on WiFi).
Most confusing is the way the Cellular Data button looks on their dashboard (or whatever this is called):
On my iPhone 8, which works fine, that same icon has a white symbol in the middle of the green circle. On the kids' iPhones, it looks like above: green circle but greyish symbol.
What's with that symbol, and what might cause this?
