Can I use a sim card in this model

This model does not support the use of a SIM card. You would need an upstream router with SIM support to use a SIM card FTTech

Any grand stream models to recommend for 50 users only

Grandstream specs for the UCM6301 PBX show: Users: 500 Concurrent calls (G.711): 75 Max concurrent SRTP calls (G.711): 50 This PBX should work for 50 users without any issues. Thanks, FTTech

.I have 6 incoming phone lines but this system has 2 fxs ports could use any adapter or card on this device to have my 6 land phone lines attached ?

in case you need attach 8 phones to your system, you need to find the fxs adaters, most of them 2 ports for 8 phones you need 4 adapters, some come with 8 ports.
