GL.iNet GL-X3000 + FirstNet

Hello users,
I purchased an X3000, used an ATT data plan for +/- 90 Gigs. I know that it works just fine.
My employer said I qualify for FirstNet, received a firstnet sim card, tried to use my device with the sim card and it shows as NOT registered. Contacted the store... "not compatible".. tried customer service "not compatible"... checked online and others have had success and looks to be compatible. I have researched the topic and VERY few results came up.
I tried the:
AT+EGMR=1,7,“your att approved IMEI”

in the tab for manual as seen below...


it doesn't do anything when I try to use the AT+ prompt from above- and I used a donor device IMEI.... so I don't understand what I am doing wrong.

Thank you in advance for your wisdom and knowledge - as well as taking time to assist me

Hello,

  1. Is this SIM card available on other devices?
    For example, insert it in your phone and check if it is plug and play.

  2. If it requires the APN, click "manual setup" on X3000 GL GUI and fill in the APN content. Please contact the ISP operator for APN information.

  3. Please confirm whether the IMEI has been modified successfully.
    (Normal circumstances the IMEI modification should not be required)

  1. Sim card shows as available on att side
  2. APN for firstnet has 3 options, tried all 3
  3. IMEI can be changed, however the x3000 is NOT on the "capable" list for FN
    *** but runs the ATT sim just fine
  4. using a device that is "capable" (phone) prompted them to switch from data to a phone plan.
  5. have spent several hours on the phone with att trying to troubleshoot the issue BUT all fingers
    point to x3000 not on the list.
  6. pointless to pay this much for a great device when the carrier stone walls unless you buy THEIR hardware. I don't have 700-1000 dollars to buy the "recommended" one just to get the IMEI but it seems to be my only option at this point -_-

ONLY netgear device that is "compatible"
0133e76539e87a223f8e2fec24cf4824

can't find where to purchase that specific one- it's like it doesn't exist

I am not sure what to do at this point

Hello,

If this card must be on a device which it is in the "capable" list, modifying the IMEI may be feasible, but it is no guarantees that if there are other restrictions.

Please contact our technical support team through email support@gl-inet.com, cellular expert will try to check and debug it to see if this SIM available to work on the GL X3000.
