Mudi Sim card not providing data

Have an Embeded Works IoT sim card and it says i need to set up the APN by adding " uscc00000.enterprise0.usc-cdp"

I log into the router using the GLiNet app, go to the internet tab, go to the cellular area, hit modify to the cellular connection, paste the above adress into the ApN, hit submit, it grinda for a bit, then returns to the internet tab, but there, a wheel spins by the cellular info and it never connects. The signal strangth says excellent, so the sim is seeing a tower.

What am i missing?

Please confirm whether this SIM card is available on other devices? For example, on the phone or USB modem?
