Turkey is not part of O2's Travel Inclusive Zone, so you will not automatically roam for free there. Instead, O2 customers need to add a bolt-on before travelling, or consider a local eSIM as an alternative. The good news is that options exist for both Pay Monthly and Pay As You Go customers.

Is Turkey included in O2's free roaming zone?

No. O2's Travel Inclusive Zone and Travel Inclusive Zone Ultimate cover a range of European and international destinations, but Turkey sits outside those zones. That means your standard UK allowance does not simply carry over. You will need to take action before you fly.

How does O2 roaming work in Turkey?

The main route is the O2 Travel Bolt On, designed specifically for travel outside the O2 Europe Zone. You add it before you leave, and it gives you access to data, calls and texts at a daily rate rather than per-megabyte charges. O2 also offers Data Roaming Bolt Ons for customers who need data in destinations outside the standard inclusive zones.

For international calls back to the UK or to other countries, the O2 International Bolt On provides discounted calling rates to over 200 countries, which can reduce costs if you plan to call home regularly.

How much data can you use in Turkey on O2?

On eligible plans, O2 states: "Whether you're on Pay Monthly or Pay As You Go, use your data (up to 25GB), minutes and texts at no extra cost." That 25 GB cap applies when roaming on plans with inclusive data abroad. Once you hit that limit, charges or speed restrictions apply, so check your plan details in My O2 before you travel.

Pay As You Go customers

Selected Pay As You Go plans include an allowance for discounted international calling. The specifics vary by plan, so log into My O2 to confirm what your particular tariff covers before departure. Do not assume your home allowance transfers.

Should you use an eSIM instead?

If O2's bolt-on pricing feels steep for a longer trip, a travel eSIM is worth considering. As of May 2026, Holafly advertises a Turkey eSIM from £3.79 per day for unlimited data. They also offer options with fixed allowances, such as 500 MB, at lower price points. An eSIM lets you keep your O2 SIM active for calls and texts while using the eSIM for data, which can keep overall costs down on a week-long holiday.

You'll need to purchase an O2 Travel Bolt On before travelling to avoid per-megabyte charges. Alternatively, you can consider a local eSIM such as Holafly, which starts at £3.79 per day for unlimited data. ### how much does O2 Travel Bolt On cost for Turkey O2 offers the Travel Bolt On as a daily rate option for destinations outside the Europe Zone, including Turkey. The exact daily cost varies depending on your plan and the specific bolt-on you choose, so you should check My O2 or contact O2 directly for current pricing before you travel. ### can I use 25GB roaming in Turkey with O2 The 25 GB roaming allowance applies only to O2's Travel Inclusive Zone destinations, which does not include Turkey. In Turkey, you'll be limited by whichever bolt-on you purchase, so you should add a Travel Bolt On or Data Roaming Bolt On before travelling to ensure you have sufficient data. ### what's the cheapest way to get data in Turkey as an O2 customer An eSIM alternative like Holafly offers unlimited data starting at £3.79 per day, which may be cheaper than O2's Travel Bolt On depending on your usage. Compare this with O2's daily bolt-on rates by checking My O2, as costs vary based on your plan and travel duration. ### do O2 Pay As You Go customers get roaming in Turkey O2 Pay As You Go customers can roam in Turkey, but they must add a Travel Bolt On or Data Roaming Bolt On first, as Turkey is outside the free roaming zone. Once a bolt-on is active, Pay As You Go customers can use data, calls and texts at the daily rate specified in their chosen bolt-on. ## Sources 1.
