Maryland-specific considerations
MARC and Metro riders get good coverage — T-Mobile and Verizon are most consistent underground.
Boaters and waterfront residents favor Verizon for reach across open water and marshland.
Deep Creek Lake and the western parks have spotty service — Verizon is the safe pick.
Older Baltimore rowhomes and government buildings can block signal; Wi-Fi calling and low-band help.

Bottom line
Most Marylanders live in the Baltimore-Washington corridor where any network works, so buy on price — US Mobile or Visible+ win. For Western Maryland, the Chesapeake, or the lower Shore, Verizon's reach is worth paying for.
