Tips for Using Holafly in United Kingdom

Install before you fly

Download the Holafly eSIM profile while you are on WiFi at home. This ensures everything is ready when you land in United Kingdom.

Verify network selection

After activation, check that your phone is connected to Three. Go to Settings > Cellular > Network Selection and verify the network name.

Enable data roaming

Some phones require "Data Roaming" to be enabled for eSIM plans to work abroad. This is safe with an eSIM since you are using a prepaid plan, not your home carrier's roaming.

Contact support if needed

Holafly offers customer support via their app, email, and live chat. If your eSIM is not connecting in United Kingdom, reach out before troubleshooting on your own.
