The internet is a lifeline for 'dwellers but it not always available in the ways it is for sedentary folk. There are two major challenges:
Mobile (or “cell” data) is the internet access provided by mobile telecomm networks.
Often you can buy data at cheaper rates. Mobile Virtual Network Operators (MVNO) are resellers who buy excess capacity from major networks and sell it to customers at reduced prices. Examples: Boost (Sprint network), U.S. Mobile (Verizon network) and many others.
If you want to find an MVNO for your preferred network, search for “verizon mvno”, “T-mobile mvno”, etc.
