GB100 or Queclink with AT&T?

I've got a GB100 (two actually) that works perfectly on T-Mobile, but can not get it to register to the AT&T network with one of their IoT SIMs. APN is set correctly, but it's not even getting to that point, it won't register on the network.

Anyone ever had any luck with a GB100 or similar cell chipset on AT&T in the U.S.?

I think your issue is that the AT&T iot sim's are basically 3-4g LTE and the GB100 is 2g only. Pretty well dead in the USA and going down in Canada this coming June 2020 Hope this helps SNO
