Things to Consider When Joining Three

To choose the right plan, potential customers should keep a few points in mind:

  • Check Network Coverage: Before signing up, it is essential to use the official coverage checker on the Three website to ensure a strong 4G and 5G signal in a user’s home and work areas.
  • Cashback is via Third-Party Sites: A large cashback offer is typically redeemed through a cashback website (like BudgetFitter). Customers must click through from that site and follow the specific terms to ensure the cashback tracks correctly.

Customers can get the most value from their plan with these tips:

  • Download the Three+ App Immediately: As soon as the SIM is active, download the rewards app to start taking advantage of the exclusive offers.
  • Consider 5G Home Broadband: If looking for a new home internet provider, check the availability of Three’s 5G service, as it can often offer faster speeds at a lower price than fixed-line alternatives.
  • Use the Three App to Manage Your Account: The main Three app makes it easy to check usage, view bills, and manage account settings.
