One of the things that makes our service great compared to "the other guys" is that our SIM cards are activated specifically for the router they come with. This makes our service a lot more reliable than others.
Since our partner network is not a big fan of seeing SIM cards in other devices, we ask that you not use it in any other device. Doing so will jeopardize your service.
However, the router that we provide is one of the best LTE routers on the market, so there's not a big reason to switch to any other device!
