@OregonLTE is correct. The Telit command for band selection is AT#BND=<GSM band>[,<UMTS band>[,<LTE band>]]

And the chipset is Qualcomm, so standard Qualcomm LTE bandmask values apply.

The Telit manual doesn't give an example of its use, so I'm not sure if you can just use eg:

AT#BND ...

AT+QENG="neighbourcell"

It needs to be run several times, and over a period of time. the contents can change dramatically, even in a fixed location (depending on whether the modem is thinking of switching bands).

You'll need practice interpreting the result.

Bands don't show directly in the ...

Sierra modems use a Qualcomm chipset. The L860 uses an Intel chipset, and many things "under the hood" are very different.

Oops, my mistake. I've been working on my Fibocom L860 too long. The LM960 is a Telit modem, so the commands I gave before this edit won't work.

Ancient memories are coming back.

If the EC25-AF is in MBIM mode then OpenWRT may have a problem with roaming. Please see: https://forums.whirlpool.net.au/thread/ ... p=72#r1425

I have a Hologram SIM. It's specifically for IoT. That's 3GPP access technology types 8 (LTE Cat M1) and 9 (LTE Cat NB1).

The EC25-AF supports neither of these. That's not to say the Hologram SIM won't work with access technology 7 (normal LTE). It may or may not, depending on the provider the ...

More on this:

What does the command AT+QCFG="gpsdrx" return on the EM20-G?

If supported, this command determines whether GPS shares the diversity antenna.

You can set the GPS receiver to activate automatically on modem start with the AT command:

AT+QGPSCFG="autogps",1

Restart it to activate obviously.

Then you can read your position at any time with:

AT+QGPSLOC=2

This gives your location in decimal degrees. Use zero or one instead of two in that ...

I am trying to find the number associated with my sim card in a Mikrotik SXT with a EC25-AF Modem. When I run AT+CNUM it returns "OK" but no number. Any ideas?


Most likely the SIM doesn't have the number written on it. In interactions with the provider, the modem uses the IMSI from the SIM, and ...

There's a newer version with improved Fibocom FM150 support available for testing:

For Linux users, I wrote a little shell script to display LTE band values.


#!/bin/sh

printf "%s%20s\n" "Band L-bandmask-1" "L-bandmask-2"
LBAND=1
BBAND=1
while [ $LBAND -le 48 ]

LBAND=$(( $LBAND + 1 ))
BBAND=$(( $BBAND * 2 ))

What would be the hex code for bands 14, 30, & 66 or for 4, 14, 30 & 66?

I am have a hard time finding the value for band 30

right now I am returning:
+QCFG: "band",0x260,0x2000000003300185a,0x0

Currently it default connects to band 2 and 15

If it ever connect to 30 or 66 my speeds go from ...

All bands for the EP06-E specifically:
AT+QCFG="band",8d0,7e00000000000000000000000000000000000000000000ff000001a0880800d5,0

That should read:

AT+QCFG="band",8d0,1a1880800d5,0
