So I was able to confirm today that the device did in fact suspend my service. I had to go to AT&T store to reactivate!
I just got off the phone with an agent, they were finally able to add the IMEI. I referenced it as a Quectel RM520N-GL Question to GL.iNet, is it possible because I bought it from the global store that it wouldn’t be registered as a proper IMEI out of the box?
MY speeds are much slow 80 Mbps down and 10 Mbps up, but my plan is unlimited only at 100Mbps max. Which is fine for most things.
Ugh, spoke too soon. Upon reset of device it blocked it again. They are now telling me it is showing as 2G in their systems for some reason and unsupported. Still working to try to get this resolved.
Update: AT&T is insisting it’s not supported. They even went as far as saying they would send me a Netgear router for free 
Of course I would have to setup a new account and lock myself into a contract.
Anyone from GL.iNet watching this thread? Can you please weigh in on whether or not the device is officially supported by AT&T? I know it’s brand new, so perhaps you are still getting it approved? Thanks!
I have already told you there are many ATT users here in the forum! Just use the search function to get all posts!
Yea and I told you AT&T doesn’t support the model, which turns out to be true as well. They won’t support it on the ultra business wireless broadband plan. That needs at cat18 or higher device. Offered to change my plan, but I’m trying to escalate and get it supported.
How does ATT know that you are using this modem? From the IMEI or something else?
You can refer to this post to change your modem IMEI to Net gear’s and try to connect again: IMEI change - #18 by alzhao
I will later write a full detailed post about it. In general I used Ethernet cable from my PC to the modem then I disabled many unneeded functions using AT commands. Lastly, I disabled unneeded network functions in openwrt and enabled other useful ones like NAT offloading …

I am having a similar issue trying to get 5g on the x3000. If I try apn nrbroadband I get no connection at all. Only apn broadband works but I’m only getting 4g. Once in a while the cellular page will say 5g but it is not. There seems to be an error somewhere?
You’re right the the page has error sometimes shows 5G while it is really connected to 4G. But once you check the “Cells info” like what you did, you can confirm.
As for the APN, you need to check your Internet provider. Some providers have different APNs for different customers.
Are you sure you have good 5G signal near your location? If yes, the modem should be able to connect to it automatically. Also, upgrade to the latest beta firmware as it is more stable.
I have verified apn with the provider. Other people have no problem getting 5g in the same location. I have contacted customer support @ at&t and they assure me that 5g has been provisioned on this line. It is included with my plan. When I try using nrbroadband apn I get the following…
And I am on the latest available firmware.
The main reason I upgraded to the x3000 was for the 5g so this is getting frustrating.
Please try APN of Phone or Enhancedphone. We used these two APN with the ATT card in past month, and it works fine.
Those are apn for phone plan. Those don’t connect at all. I have tablet plan which uses broadband and nrbroadband for 5g
We went to ATT store and asked for a sim-card for the 5G Router, the clerk sold us such card and told us to use the APN of phone.
How you get the tablet plan, from ATT store also? Perhaps we need to buy the same card and test it.
It is the $20 stand alone unlimited tablet plan. You have to ask for it specifically. Not all reps know about it.
Thanks a lot. We will check if can buy such plan from ATT store.
If anyone cares, I think I figured out my issue. For this business wireless broadband ultra plan you are forced to use 4g and not 5g. I was finding the device kept trying to connect to 5g and by doing so it caused att to disable. I blocked all the 5g bands and now it seems to work. It’s definitely a bit slower l, but at least I get “unlimited” data capped at 100mbps. Let’s see if it sticks.
Thanks for this information. If you use this card in Tablet or phone, what’s the behavior? Also need to use 4G not 5G, and what’s the bitrate?
I know this is an older post, but I just received the Spitz AX, called ATT and gave them the new IMEI. I had to do a “Manual Setup” and set the APN to “nrbroadband”. I am getting the 5G connection based on the symbol in the UI. I am outside of Chicago and it seems to be working. I only get about 100 down and 50 up, but at least I am able to get connected.

Interesting, maybe they added support for the device. Can you reboot and see if it still maintains connection? I was always connect first time, but once I lost connection and reconnected it would disable my account.
