⚡ Three Turkey Roaming Key Facts

  • Daily Fee: £5.00 per 24 hours under Go Roam Around the World.
  • 14-Day Trip Cost: £70.00 in roaming pass fees.
  • Data Cap: 12GB monthly maximum (even on unlimited UK plans).
  • Cheaper Alternative: A 20GB Turkey eSIM costs £15.00 total on Turkcell with zero daily pass fees.

How Three Go Roam Works in Turkey

Three divides its international roaming into two tiers:

  • Go Roam in Europe: Costs £2.00 per day for EU destinations.
  • Go Roam Around the World: Costs £5.00 per day for 21 non-European destinations, including Turkey, the USA, Australia, and New Zealand.

The £5.00 daily pass activates automatically the moment your handset uses mobile data, makes a phone call to a UK or local Turkish number, or sends an SMS. The pass lasts for 24 hours from the exact moment of activation.

The 12GB Monthly Fair Use Limit

One of the biggest surprises for British holidaymakers on Three is the fair usage limit:

⚠️ Strict 12GB Ceiling: Regardless of whether you have a 100GB or Unlimited Data allowance in the UK, Three restricts your high-speed roaming data to 12GB per calendar month in Turkey. If two people tether from your phone or you stream videos, you can easily exhaust this cap in the first week.

How to Use an eSIM Alongside Your Three SIM

You can keep your UK Three number active without paying the £5.00 daily roaming fee:

  1. Leave Three SIM On: Keep your Three SIM card active in phone settings, but ensure Data Roaming is OFF. Receiving incoming SMS verification texts from your UK bank is completely free.
  2. Activate Turkey Travel eSIM for Internet: Set your new travel eSIM as the Default Mobile Data line with Data Roaming ON.
  3. Disable Cellular Switching: Turn off "Allow Mobile Data Switching" so your device never accidentally routes background data through Three.
