Boron LTE - what should the IMEI Tech Type be?

We just got the Boron LTE working with our AT&T APN and sims, went over to Jasper (simcontrolcenter) to take a look and noticed that the IMEI Tech Type was 4G and not LTE.

We also noticed in sim diagnostics that there is a line for an APN (our APN appears there) and another line for LTE APN:

The Boron LTE radio seems to be working fine. Our firmware is working fine. I guess my question is whether the radio is running in its most optimal mode and whether we need to specifically obtain an LTE-capable APN?

I don’t know the answer to your specific question, however the Boron LTE (u-blox SARA-R410M-02-B) does not have fallback to any technology other than LTE Cat M1 or NB1, so there’s no other mode it can be operating in.
