This is a cellular 4G/5G modem which can be used with any Cellular service which uses T-Mobile network (such as any of their MVNO carriers). This WILL NOT work with Cellular carriers that use AT&T or Verizon towers -- only T-Mobile, which includes Metro by T-Mobile, Boost Mobile, Mint Mobile, Ultra Mobile and Tello.This unit is a wired gateway (no Wifi antennas). This can be connected to a Wifi Router or to a wired switch in order to share service with more than one device. It can be used outdoors or as an indoor unit, depending on the signal strength of the nearest T-Mobile tower.
Common applications are for networking (backup Internet source for remote access to equipment), remote cameras, retail store or restaurant backup internet source for Point of Sale (Credit Card Processing) system, etc.
** If you are unsure if you have a strong enough T-Mobile signal, you can use a friend's phone which uses T-Mobile, Boost, Mint Mobile or Tello to test the location in mind. Alternatively, a Mint Mobile SIM chip (uses T-Mobile towers) can be purchased for just $2.00 at Target, Walmart and other retailers that provides a 7 Day access trial. This will let you see how good the signal is in your area. That SIM chip can be inserted into a phone in order to be able to do speed tests or use a free mobile App to measure the signal strength **
