Why You Need Unlimited Data
This article is sponsored by Sim Local. As always, we only recommend things we’d actually use ourselves, and the editorial take here is our own.
Hi there, traveler! Picture this: you’ve just landed in Istanbul, you’re sipping your first Turkish tea in a little café in Sultanahmet, and your phone tells you your data is gone. On day two. And here’s the catch most people don’t know about: once you’re in Turkey, getting more data is not that simple.
A little confession before we start: until I researched this guide, I had never bought an eSIM. I always assumed the process would be complicated and the prices wouldn’t be worth it. Then I went through Sim Local’s buying process for Turkey, and honestly, it changed my mind about eSIMs for future trips.
So, what is the best eSIM for Turkey? For most travelers, it’s an unlimited plan bought before you fly, and Sim Local’s Turkey Unlimited is the one I’d pick: 5GB of full-speed data every day on Vodafone and Türk Telekom, from US$18.75 for 7 days. In this guide, I’ll show you why unlimited matters so much in Turkey, which plan to pick, how Sim Local compares, and exactly how buying and setting it up works. Let’s get into it!
Why can’t you top up an eSIM once you’re in Turkey?
Here’s what I found when I looked into it. From 10 July 2025, Turkey’s telecommunications regulator, the BTK, began blocking access to international eSIM providers that aren’t licensed to operate in Turkey, through three decisions issued in July and September 2025. The block covers their websites and apps on Turkish networks, and Sim Local is among the providers affected, along with many of the best-known eSIM brands.
What does that mean for you? You can’t buy a new eSIM or top up your data once you’re in the country, even if the app shows a top-up option on your plan. So if you pick a small plan and burn through it navigating Istanbul’s maze of streets or posting your Cappadocia balloon photos, you’re stuck hunting for café Wi-Fi for the rest of the trip.
That’s why, for Turkey, I’d go unlimited every time and buy and install a plan that covers the whole trip before leaving home.
Who is Sim Local, and is it a good eSIM provider for Turkey?
Sim Local has been in the travel connectivity business for over 15 years and has served more than 4 million customers. A few things set it apart from other eSIM providers:
- You can find it at the airport. Sim Local has stores in European airports including London Heathrow, Madrid, Vienna and Athens, plus vending machines in more than 100 airports around the world.
- Calls and texts on some destinations and plans, which isn’t common among eSIM providers. (For Turkey, the unlimited plans are data only.)
- Find My Plan, a simple four-question tool that recommends the right plan so you only pay for what you actually need.
- A generous daily allowance. According to Sim Local, its daily full-speed cap is more generous than many other providers’.
- 24/7 customer support from a real team of people, on WhatsApp and email.
Which Turkey eSIM plan should you choose: Unlimited or Unlimited Pro?
Sim Local has two unlimited options for Turkey, both on 4G and 5G, and each comes as a 7-day or 15-day plan. Here’s how they compare (prices at the time of writing, November 2026):
| Unlimited | Unlimited Pro | |
|---|---|---|
| Full-speed data per day | 5GB | 10GB |
| 7 days | US$18.75 | US$28.00 |
| 15 days | US$41.00 | US$51.50 |
| After the daily allowance | Up to 1 Mbps until it resets | Up to 1 Mbps until it resets |
| Hotspot and tethering | Included | Included |
| Best for | Most travelers: city breaks, beach holidays, social media | Remote workers, creators, heavy hotspot users |
Both plans are data only, so there’s no local phone number, but WhatsApp, FaceTime and other calling apps work over data as usual. Your full-speed allowance resets every 24 hours from first use, and once you’ve used it up you keep browsing at a slower speed until the reset, so you’re never completely offline.
Is Sim Local the best eSIM for Turkey? How it compares
Here’s how Sim Local’s Turkey Unlimited plan stacks up against the unlimited Turkey plans from two other popular providers (prices from each provider’s website, November 2026):
| Sim Local Unlimited | Nomad Unlimited | Yesim Unlimited | |
|---|---|---|---|
| Plans and prices | 7 days US$18.75 15 days US$41.00 |
5 days US$17 10 days US$28 |
7 days US$27.72 15 days US$44.40 |
| Price per day | US$2.68 to 2.73 | US$2.80 to 3.40 | US$2.96 to 3.96 |
| Full-speed data per day | 5GB, then up to 1 Mbps | 2GB, then 1 Mbps | Not stated, fair usage policy applies |
| Hotspot | Included | Included | Depends on the operator |
At the time of writing, Sim Local works out the cheapest per day of the three, and its 5GB a day is more than twice Nomad’s daily full-speed allowance.
How much data do you need in Turkey?
If numbers like 5GB mean nothing to you, you’re not alone! Sim Local’s app breaks it down nicely. According to its guide, 1GB is roughly 25 hours of Google Maps or 10 hours of WhatsApp calls, while 5GB gets you about 7 hours of scrolling and uploading on Instagram or TikTok, or 5 hours of video calls.
So with 5GB every single day, the regular Unlimited plan covers pretty much everything a typical traveler does. Go for Unlimited Pro if you work online, stream a lot, or plan to share your connection with a laptop or your travel buddy.
Does a Turkey eSIM work everywhere in the country?
In all the places you’re most likely to visit, yes. Sim Local’s Turkey plans run on Vodafone and Türk Telekom, two of Turkey’s leading mobile networks, with 4G and 5G where available. Coverage is strong in Istanbul, Ankara, Izmir, Antalya, Cappadocia and Bodrum, along with the other popular destinations. In remote areas like Eastern Anatolia, around Mount Ararat, parts of the Black Sea region and up in the mountains, the signal can get patchy. If a road trip into the countryside is on your list, download offline maps before you set off.
How do you buy a Turkey eSIM? (It took me seconds!)
I tested the buying process in the Sim Local app, and the purchase itself took me about five seconds. Not sure which plan you need? The Find My Plan tool asks you four quick questions and recommends one based on how long you’re traveling and how much data you use. Your eSIM codes arrive by email straight away, and it’s buy now, use later: the plan only starts when it first connects to a network in Turkey, and you have up to 6 months to activate it, so you can buy well ahead.
One tip from my own test: check your phone before you buy. Mine turned out not to support eSIM at all! If yours does, you’ll find an “Add eSIM” option in your mobile or SIM settings. If it doesn’t, you’ll need an eSIM-compatible phone for the trip, so sort that out before you buy.
How do you install a Turkey eSIM, step by step?
- Install it before you fly. Because of the restrictions in Turkey, Sim Local recommends installing your eSIM before you arrive. Do it on Wi-Fi, using “Install Plan” in the app or the QR code in your email.
- Don’t delete it! An eSIM can only be installed once, so keep it on your phone until your trip is over.
- Adjust your settings. Keep your home SIM as your voice line so you still get calls and texts on your own number, set mobile data to your Sim Local eSIM, and turn on data roaming for the eSIM. Turning off mobile data switching stops your home plan from sneaking in roaming charges. The app walks you through all of this for your exact phone.
- Land and connect. Your plan starts automatically the moment the eSIM connects to a network in Turkey. Remember that you have up to 6 months from purchase to activate it.
Who is a Sim Local Turkey eSIM best for?
- Families, who need maps, bookings and messages working for everyone, all day.
- Solo travelers, who want affordable data without roaming bills or hunting for Wi-Fi.
- First-time eSIM users (like me!), thanks to Find My Plan and the step-by-step guides in the app.
- Road trippers and groups, since hotspot is included and one phone can keep the whole car connected.
- Remote workers and creators, who should go straight for Unlimited Pro and its 10GB a day.
Frequently asked questions about Turkey eSIMs
📶 What is the best eSIM for Turkey?
An unlimited one, bought before you travel, since you can’t buy or top up an international eSIM once you’re in Turkey. Sim Local’s Turkey eSIM gives you 5GB or 10GB of full-speed data a day on Vodafone and Türk Telekom, with reliable coverage across the major cities and tourist spots.
✈️ Do I need to install my Turkey eSIM before I arrive?
Yes. Sim Local recommends installing it before you travel because of the local restrictions. The plan then switches on automatically when it first connects to a network in Turkey.
♾️ Is the data really unlimited?
Yes. You get 5GB (Unlimited) or 10GB (Unlimited Pro) of full-speed data every day. After that, you keep browsing at up to 1 Mbps until your allowance resets 24 hours later, so you never lose your connection during your plan.
📱 Can I use my phone as a hotspot?
Yes! Hotspot and tethering are included with both unlimited plans, within the daily full-speed allowance.
🌍 Is an eSIM better than roaming in Turkey?
For most travelers, yes. Roaming on your home plan is easy but can get expensive fast, and a physical local SIM means finding a shop after a long flight. An eSIM is set up before you leave, works as soon as you land, and leaves your home SIM in place for calls and texts.
☎️ Do I get a Turkish phone number?
No. The Turkey unlimited plans are data only, so use WhatsApp, FaceTime or similar apps for calls.
The bottom line
And there you have it! Turkey is one of those places where you really want your data sorted before you go, and that’s why an unlimited plan is the best eSIM for Turkey: it takes the whole problem off your plate. I went in thinking eSIMs were fiddly and overpriced, and came out planning to use one on my next trip. Install it at home, land, and spend your trip enjoying the bazaars, the beaches and the food instead of counting gigabytes.
Safe travels, and enjoy every minute of Turkey!
Love,
Marija
