People say to just look up the IMEI in the "dash board" or "web panel,"

Would it be printed on case or under sim cover?

How do I get an AT&T SIM for my X750v2

I took my LTE modem (GL-X750V2C4) to two different AT&T stores, and both said they needed an IMEI number to activate a SIM card. They tried to “look it up by serial number” but “it didn’t come up”. Same exact process at both stores. I only bought the device because the website specifically says that it’s AT&T compatible. Please advise.
