Setting up your iPhone for data access with a BT One Phone SIM

Before you do, you'll need to remove any existing configuration files you've previously downloaded. Instructions on how to do this can be found here.

  1. Connect your iPhone to the internet (using wi-fi if you don't already have mobile internet access).
  2. Open the Safari browser on your iPhone.
  3. Go to www.bt.com/business/iphonesettings/btop
  4. From your iPhone, not your computer, click on the link below to download the configuration file.
