What these numbers can't tell you
- One test is one moment in one spot. Speed changes with the building you're in, your phone, the time of day and how busy the towers are.
- The town is the one the tester picked. cape.monster never asks for your location, so a test counts where the person said they were.
- For your street, use Cape's own map. Cape's coverage map shows where Cape has service.
- Heavy months can slow down. Cape says that after 50GB of use it may temporarily slow data to 256 kbps.
