EM7455 in Lede/OpenWRT with a TMobile SIM.
SIM is good, I confirmed with carrier and I can switch it to a tablet and I get data.
Board/OS is good, I can connect fine with Sprint when I’m on the correct Sprint at!band in QMI mode.
Here’s my AT!GSTATUS?
Current Time: 1621 Temperature: 32

It shows registered and attached, but EMM says Registered PLMN Search
Index, Name, GW Band Mask L Band Mask TDS Band k
0E, TMobile, 0000000000000000 000000000000080A 0000000000
(This is bands 12, 4, and 2)
uqmi shows the IP/Gateway/DNS, and I made sure /sys/class/net/wwan0/qmi/raw_ip is Y
I set up my wwan0 IP addr in raw_ip mode, and the default gateway through route.
I can’t ping or get any data, though.
This same device works with a Sprint SIM, when I’m on the correct Sprint AT!band. I’m just getting nothing for TMobile, and the only difference I see is that PLMN Search on the EMM line of GSTATUS.
Any ideas of what to check?
