For years I have used Freedompop's 200 MB free service (on AT&T network). they are phasing out that plan , replacing with "Fremium" SIM. New plan only has 25MB data so that won't work...

I have tried Red Pocket GSMA (AT&T) SIM & GSMT (T mobile) SIM, also US Mobile (T mobile), which I have used in the past. None work. Has Google changed the API or something. Error is shown below:

Internet access through WiFi also appears dead. My Q7 new came with T mobile SIM, Cellular radio was updated when T mobile upgraded their network years ago...
