Peace be upon you A mobile router from stc, honestly I haven't tried it with other SIM cards. It might be unlocked, meaning it supports SIM cards other than stc, or only stc. It supports 2G-4G frequencies, and it's written that it supports 5G, but I haven't tried it, to be honest. It supports more than 7 connections. It supports Ethernet and barcode connection. May God bless you.
