Turkey sits just outside the EU's "roam like at home" zone, so the free roaming you enjoy across Europe stops the moment you land in Istanbul or Antalya. A travel eSIM for Turkey fixes that: a second, data-only line you install before you fly, so you step off the plane already online — maps, WhatsApp, your ride to the hotel — without a surprise roaming bill.
This guide covers how a Turkey eSIM works, what it costs, how much data to buy, and how to set it up in a few minutes.
Why you need an eSIM for Turkey
Turkish networks are not part of EU roaming. Depending on your home tariff, that means a daily roaming pass of several euros or, worse, per-megabyte charges that turn a two-week holiday into a three-figure phone bill.
A travel eSIM sidesteps all of it. Your normal SIM stays in the phone for calls and texts on your usual number; the eSIM carries the data on a local Turkish network — and you pay a fixed price you see before you buy.
eSIM Turkey: prices and plans
Plans are data-only and pay-as-you-go — no contract, no auto-renewal. You pick a data size and a validity window, pay once, and that's it. Sizes run from small day plans up to larger multi-gigabyte plans for longer stays, and you can top up from your phone if you run low.
Prices start at just a few euros for a week of data — typically around half what the big global eSIM brands charge for the same allowance. You'll see the exact live price on the Turkey eSIM page, and the plan card at the foot of this guide shows the current "from" price.
Coverage and speed
Horizon's Turkey plans run on a major local network with 5G where available (and fast 4G/LTE everywhere else), so you get full-speed data across Istanbul, Cappadocia, the Aegean and the Mediterranean coast. Hotspot and tethering are supported, so you can share the connection with a travel companion or a laptop.
How much data do you need?
For a typical one-to-two-week trip:
- Light (maps, messaging, the odd call): 3–5 GB.
- Normal (photos to the group chat, some scrolling, video calls home): 8–10 GB.
- Heavy (hotspot, lots of streaming): 15 GB or more.
Not sure? Start modest — you can top up in a minute without hunting for a shop. Our guide to how much data you need breaks it down by activity.
Set up your Turkey eSIM in three steps
Do it on Wi-Fi at home before you travel:
- Buy and install the Turkey eSIM — you'll get a QR code by email. Scan it to add the data line (check your phone is eSIM-compatible first).
- Leave it switched off until you arrive — billing starts when it first connects to a Turkish network.
- Turn on the data line when you land and set it as your mobile data. Keep your home SIM on "calls and texts only" so nothing roams in the background.

Buying an eSIM for Turkey
Buying takes a couple of minutes: choose your plan on the Turkey eSIM page, pay by card, and the QR code lands in your inbox. Because it's data-only, you keep your own number and your existing apps and contacts work exactly as before. New to eSIMs? Start with what is an eSIM.
Frequently asked questions
Which eSIM is best for Turkey? The one that matches your trip length and data habits. A single-country Turkey eSIM is cheaper and simpler than a global plan if Turkey is your only stop — you get local 5G, keep your number, and pay a few euros.
Does an eSIM work in Turkey? Yes — modern iPhones and most recent Android flagships support eSIM, and Turkish networks carry the data. Check the supported devices list if you're unsure about your phone.
Do I keep my phone number? Yes. The eSIM is a separate data line; your home SIM stays in the phone for your usual number, calls and SMS.
Can I use it as a hotspot? Yes — tethering is supported, so you can share the connection with another phone, a tablet or a laptop.
The short version
Turkey is outside EU roaming, so buy a Turkey eSIM before you fly, install it on Wi-Fi, and switch it on when you land. You keep your number, get local 5G, and pay a few euros instead of a daily roaming fee. Travelling elsewhere too? We also cover the USA, Thailand and Japan. Grab your Turkey plan now and step off the plane already connected.
