CA does not support B1+B3
The list of CA support is as follows:

B1+B1/B5/B8/B20/B28;
B3+B3/B5/B7/B8/;
B20/B28;
B7+B5/B7/B8/B20/B28;
B20+B32;
B38+B38;
B40+B40;
B41+B41

Note that the SIM card and carrier has a lot to play here - so forcing the modem to lock to bands can lead to less that desired outcomes.

SIM card has the subscription profile for the IMSI - so it’s dependent on what that particular rate plan supports.

Case in point - one of my test SIM’s is a T-Mobile MVNO, and there it’s 2G only (GSM/GPRS) and in my particular region, it’s barred from accessing the T-Mo network as it’s not 3G. If I go to Taiwan or Germany, it works, just not in the US, and this is a US based SIM card with a US based MSISDN.

Thank you for this! It took me a little bit to figure out how to do this my self, but it sure made this much easier.

FYI, for anyone like me: I used putty to SSH in and googled VI editor to figure it out.

51

Why did you use SSH? You can send AT commands directly from the GL UI.

52

By using SSH I was able to edit the file mentioned above, which saved all the AT commands to the shortcuts for the AT commands instead of having to enter them manually. That way I don’t have to remember them. I like it.

53

Ah i see, some of the commands don’t stick?
Then yeah you did good :smiley:

54

I had a lot of trouble with this. It would be nice if the GUI pulldown for the AT set band had the T-Mobile 66 and 71 with the EC25 AF cards. I edited the index.js file to add the two bands at the end, but they still don’t show up in the list afterwards. It still only goes up to Band 43.

I also tried some of the commands that were posted in this thread, but I was just getting errors with the one that I wanted, band 71. It took me a while to get my MiFi working again, because 71 is the only band that I could pick up at my home.

I finally got it working again, using the following commands - EC25-AF specific:

Default bands:
AT+QCFG=“band”,2e0,42000000000000381a,0

Band 71 only:
AT+QCFG=“band”,2e0,400000000000000000,0

Band 66 only:
AT+QCFG=“band”,2e0,20000000000000000,0

Band 71 and 66:
AT+QCFG=“band”,2e0,420000000000000000,0

Thanks for this thread. I am trying to debug why my AC25-AF in X570 Spitz is so much slower than my phone. My phone gets like 40Mbps on band 66. So I switched to band 66 in AC25-AF using the above command. Unfortunately it gets only 20Mbps in band 66. How do I get back all T-Mobile bands?

Does this enable all T-Mo bands? B2/B4/B5/B12/B13/B14/B66/B71

AT+QCFG=“band”,2e0,42000000000000381a,0

Do you guys get over 20Mbps on T-Mobile with X570 Spits and AC25-AF?

57

There is should be a preconfigured command to reset all band. I think it is the one you posted

58

@rushpi I have seen as high at 38Mbps on Tmobile with the EC25 in an X750. For me and the towers I am connected too, B4 & B66 were the fastest (no B71 near me) B2 was slower but good ping times and B12 was painfully slow.

@dwoslc90
Quick question… I’ve been using
AT+QCFG=“nwscanmode”,3,1
to lock to LTE, and it works when I check the value… But it doesn’t survive a reboot.

I think it should survive a reboot of the device.

Any thoughts on that? When you execute the command, what ‘port’ are you sending it to?

60

@dandan I think there is an AT command to save settings to the modem.

Would be nice if this simply became a firmware feature :slight_smile:

62

It has been done in the latest firmware… The post is old

63

Hello,

The carrier agregation doesn’t seem to be working in my Spitz, the 4G speeds are very slow.

How do we configure the CA ?!

Thanks

64

Which module are you using?
What is the settings?

Pls upgrade to 3.215 and choose qmi mode

65

  • Spitz v2 w/ EP06-E

  • The bands are in default mode (no locks on specific one)

  • When running the check CA info command, I only get “OK” response

  • I have already 3.215, How do I choose QMI mode ?

Thanks
