Hi ALL, I just want to confirm how the Dual SIMs in MG51/51E work..   Assumed i have the Broadband connected to WAN1 ( MX ) and WAN2 ( MG51/51E ) connected to port 2 of the MX..   The MG51/51E have dual SIMs... I configured SIM1_VZ is Primary LTE backup and SIM2_ATT is a Secondary LTE backup.   Question i want to confirm here is... The Secondary SIM2_ATT only become Active and pass traffic when Both WAN1 BB circuit in MX  and Primary SIM1_VZ in MG51/51E are completely DOWN. Is that correct ? Thanks ... View more
