LTE Registration Denied

Hi,

I don’t have a lot of experience with the mikrotik products, apologies in advance if I say something completely off.
MikroTik LHG LTE kit are the devices I have, one of them set in the EU and I’m trying to set one up in the US. Unfortunately,
the seller had shipped the “international” (international should support the freq. bands in the US imo) and not the US kit to the states
but Band 2 is fortunately in both. I tried to configure the kit but was failing to connect to an LTE operator, the RSRP detected in other
devices is very low (same SIM) and the following error is seen (logs):

00:49:26 lte,async,raw lte1: +CREG: 3, 8763, b951d0a, 7 
00:49:26 lte,async,raw lte1: +CEREG: 3,"8763","0b951d0a",7 
00:49:28 lte,async,raw lte1: +CREG: 11, 2101, 515400e, 7 
00:49:28 lte,async,raw lte1: +CEREG: 11,"2101","0515400e",7

whilst the

/interface lte cell-monitor lte1:



PHY-CELLID  BAND  PSC EARFCN  RSRP  RSRQ  RSSI  SINR  RSCP AGE                 
187                 B2        1000               -104dBm  -14dB                                 3s

Could the registration issue be due to the bad reception and what does the CREG: 11 mean?

Thanks
