WE286-Q with Sierra ME7455, modem stays *CONNECTING*

So i bought a WE286-Q to run a ATT Unlim. Data Tablet sim.

Everything looks good except that the modem just says "Connecting".

AT!Gstatus? - RETURNS:

!GSTATUS:
Current Time: 499 Temperature: 44
Reset Counter: 1 Mode: ONLINE
System mode: LTE PS state: Not attached
LTE band: B12 LTE bw: 10 MHz
LTE Rx chan: 5060 LTE Tx chan: 4294967295
LTE CA state: NOT ASSIGNED
EMM state: Deregistered Attach Needed
RRC state: RRC Idle
IMS reg state: No Srv

Fiddled around with APN settings and TTL, but nothing it making this thing actually connect to the internet.

Sim has been activated but has never been used before. I repaired IMEI to match the IMEI that is on the ATT tablet sim acc.

Not sure if i missing something .. any help is appreciated
