I purchased prepaid ATT Data Only sim card. They activated it at the store. Trying to set it up on my Pepwave UBR LTE. Installed in bank one SIM Card A. APN is still fast.t-mobile.com from previous SIM.
network Mode is AT&T, but carrier still shows T-Mobile. Any advice would be appreciated.
Change the APN…
Hi. We’ve seen the exact same issue with AT&T 5G prepaid plans including the exact plan you have. Change the APN to “broadband” and see if that helps. “Auto” will work with some AT&T plans but not that one.
