Trying to set up this device as just a mobile hotspot has been terrible. It's telling me that I need a APN and won't work unless I have one. I contacted my service provider and can't get one. I already purchased a sim card from at&t for 75 dollars for 100GB and nothing. Spent 6 plus hour calling, going to the interface and trying to connect it with the internet. Going to send it back and try a different hotspot.
