Good to know

What can affect coverage?

A coverage map shows expected service in each area, but a few real-world factors can change what you actually experience day to day.

Building materials
Concrete, double brick and metal cladding can significantly weaken indoor signal.
Your device
Older phones may not support 5G, VoLTE or carrier aggregation, capping the speeds you can reach.
Weather and terrain
Heavy storms, dense bush and hills can scatter or block signal between you and the closest tower.
Network demand
Crowded venues like stadiums or transit hubs can slow the network during peak times.

Confirm coverage before you activate

Because BlazeMobile is eSIM-only and sign-up happens inside the BlazeMobile app, you'll be asked to confirm coverage at your address before you choose a plan. The app uses your phone's location for an accurate, real-time read on what's available exactly where you are.

  • Get notified if there's planned maintenance or a known outage.
  • Re-check coverage any time — useful before a road trip or move.
