I have a SXTR with a Quectel ep06e modem in it.

I want to install both an Optus and Telstra sim in it so when I get on site I can easily check which has the best connection and use that, without having to drop the modem down off the pole and physically swap sims. Both prepaid sims, I'll just let the unused one run out.
The Optus sim has been working fine in sim slot A testing in my office. Today I activated a Telstra sim and installed it in sim slot B. APN telstra.internet, rest defaults. Two problems....
Problem 1. I can't get the Telstra sim to activate on anything other than 3G. If I disable 3G with LTE enabled it won't connect. Cell scan in the Mikrotik picks up B28, B1, B3, B7. Can anyone help me with settings to get the Telstra sim to work? It connects to LTE in my Samsung S20 so I assume the sim is properly enabled by Telstra.
Problem 2. First off the Telstra sim got jammed in slot B, took some swearing to remove it. Eventually got it out, swapped sim positions to try to problem solve - now I can't get the unit to detect either sim in slot B. They both still work in slot A. Is this "normal" for this unit? Any ideas on mods to get the sim detected?
