They have a $5/mo. plan (does not inc. taxes/fees) that is unlimited talk & text and 256 MB data when paid monthly, that increases to 768 MB monthly if you pay for 12 months up front.
They also give more "loyalty points" for annual vs. monthly payment but I didn't try to see the details of that program to see if it is something that is useful.
Another entry in the low price plan market, too bad it's not $5 inc. taxes & fees. I don't think $5 all in ever existed on AT&T?
The same folks as were behind Whoop Connect (an ACP provider). I briefly kicked the s on them. The service was OK but nothing that made me want to stay but then AT&T's network is the also ran where I'm at.
I can't speak to the quality of support as none was required in the short period of time I tried them. They are persistent. They called so often after I let service lapse I ended up blocking their number. I had given them my Google Voice number when signing up.
If you scroll down far enough on their home page (this is on mobile phone screen), just before FAQ section you should see this "pick your price" slider and # of months buttons below it.
Yes, that USM $5 plan was a great value offer from a MVNO widely viewed as a solid provider.
I wish it was still available and hope they continue to grandfather you "forever" or until you decide to leave.
