The MultiTech MTD-H5 is marketed to be 'Universal', in that they are advertised and certified for and 'should' work in networks over much of the world. Though it requires the customer to buy and insert a SIM card, and provide additional information to the DigiSnap Pro Controller (APN, etc). Please verify that the SIM card provider has adequate coverage at your project site. These cellular modems only support 3G, so they aren't as fast as a newer 4G modem. It's always best to use a cellular modem recommended/sold by the local network.
The MTD-H5 is a GSM/HSPA+ modem compatible with most cellular networks around the world.
Verizon networks and SIM cards are not supported.
