So I have three Waveshare SIM7070Gs at this point. This first one is on the pilot plan and is able to send SMS texts fairly reliably. The second two are on the maker edition flexible data plan, and it cannot connect. I have tried this sim card in both units and neither are able to send a text. I manually set the APN to hologram, they have good signal strength, theyre even able to locate AT&T, and Verizon networks. But they cannot send texts because they are “not registered”.
