1&1 Turkey Roaming 2026: Check costs and eSIM alternative
1&1 Turkey Roaming 2026: Check costs and eSIM alternative
Short answer: Turkey is not part of the EU roaming zone for 1&1. According to 1&1, countries outside the EU are divided into global zones, for which international packages or usage-based rates apply. If you mainly need mobile data in Turkey, you should check before you travel whether a 1&1 international package is sufficient or whether a separate Turkey eSIM from VoiSim better suits your data needs.
I wouldn't wait until I'm at the gate to deal with this. It's easy to make a mistake when it comes to Turkey: you have a German mobile plan, the destination is close to Europe, so it feels like normal roaming. That’s exactly where it gets confusing. 1&1 makes a clear distinction between EU roaming and roaming outside the EU. Turkey is not covered by the standard EU regulation.
Is 1&1 roaming in Turkey included?
For Turkey, you shouldn't assume that your German data allowance will simply work as it does at home. In its official roaming overview, 1&1 states that different conditions apply within the EU compared to outside the EU. In the detailed mobile price list, Turkey is listed in World Zone 3 for roaming tariff zones.
In practice, this means: check the 1&1 Control Center before you travel, review the roaming information for your plan, and don't turn on data roaming blindly. Maps, messenger apps, hotel apps, and short video clips consume data much faster than you realize at first.
What 1&1 options are there outside the EU?
1&1 offers specific international packages for travel outside the EU. According to their Help Center, these can be booked via the 1&1 Roaming Center, either before departure or after arrival. In their instructions, 1&1 mentions daily, weekly, and monthly packages, depending on the travel destination.
For Zone B, in which Turkey is listed in the official price list, 1&1 cites 500 MB as a daily package, 1000 MB as a weekly package, and 5000 MB as a monthly package as examples. Prices and availability may vary depending on your specific plan. Therefore, the safest step is always to check in your personal 1&1 Roaming Center before you book.
When does a Turkey eSIM make sense?
A travel eSIM makes sense primarily if you want to use mobile data in Turkey in a planned way and making calls via your German number is a secondary concern. Many travelers mainly need navigation, WhatsApp, translators, banking authorization, and quick searches while on the go. A separate data package is often less stressful for this, as you don't have to strain your main plan for mobile internet abroad.
With VoiSim, you buy the Turkey eSIM before your trip, install it via a QR code, and use it as your data line in the destination country. Your regular SIM can remain in the phone. The only important thing is that your smartphone supports eSIM and is not SIM-locked.

1&1 international package or VoiSim eSIM?
If you only need a very small amount of data and can find a suitable package in the 1&1 Roaming Center, the 1&1 package can be convenient. You remain entirely within your current contract and don't need to install anything extra.
If, on the other hand, you are traveling for several days, use Google Maps regularly, send photos, or need a hotspot for a second device, it is worth comparing. Then, the name of the provider matters less than the question: How much data volume do I get for the duration of my trip and how accurately can I estimate the costs in advance?
How to prepare your phone for your trip to Turkey
First, check the 1&1 Control Center to see which roaming conditions apply to your contract. Then decide whether to book a 1&1 international package or use mobile data via a separate eSIM. If you use an eSIM, install it via Wi-Fi before your flight. You should only activate it and select it as your mobile data line according to the provider's travel instructions.
A small practical tip: Save your hotel address, your first route, and booking numbers offline. That way, you'll stay calm even if something goes wrong at the airport or if the network takes a few minutes to connect upon arrival.
FAQ: 1&1 Turkey roaming and eSIM
Does EU roaming with 1&1 apply in Turkey?
No, Turkey is not part of the EU roaming zone. In the official 1&1 price list, it is listed in World Zone 3 for roaming tariff zones.
Can I book 1&1 international packages before I travel?
Yes. 1&1 explains that international packages can be booked via the 1&1 Roaming Center before you travel and activated for the desired travel date.
Can I use my 1&1 SIM and a Turkey eSIM at the same time?

Does a VoiSim Turkey eSIM have a phone number?
The VoiSim Turkey eSIM is intended for mobile data and is supplied without a classic phone number. You can usually continue to use WhatsApp and other apps with your existing number.
Where can I find the current 1&1 prices for Turkey?
You can find the binding prices at 1&1 in the Roaming Center or in the official price list. Always check your specific plan, as older contracts may differ.
My conclusion
For Turkey, I wouldn't just let 1&1 roaming run in the background. Check the terms first, then decide. If you need mobile data in a predictable way and want to avoid any billing surprises, a separate Turkey eSIM is a neat alternative.
