It’s a USIM that can be inserted in the router. Prices are the same whether you buy the router or not (different data services for this type of SIM card only). There’s a place on the website where it says SIM Card locked to touch routers only / Alfa routers only. I know that a device’s IMEI can be locked to a specific carrier but not that a SIM card can only work with specific type of devices/routers.
