I use my Pinephone on AT&T with no problem, however I had to active the SIM in a supported phone. They had shipped me a KaiOS 4G flip phone to replace my old 3G flip phone due to the phaseout of 3G service. Once the SIM was activated in their device I installed it in the Pinephone and it works fine for making and receiving calls. (I don't use mobile data though.)
