“After a satisfied test in 2024 with Yesim in Turkey, it was clear to me to go for an eSIM from Yesim also during my vacation in 2025.
Activation is super easy, it is even possible to buy it in advance and activate it at a later time (for example, when the vacation starts). Deferred activation. Very convenient.
I was curious about the connection speed in 2025 and was amazed at how fast the Internet was with Türk Telekom.
In 2025 the download speed was between 30 and 50 Mbps and the upload was super high above 90 Mbps.
The network was 4G/ LTE+ - since 5G is almost not yet built out in Turkey (only in and around Istanbul and certain soccer stadiums)
You get a Polish IP address with Yesim (Polish provider Plus) which gives the advantage of being able to access/view/use all apps and websites without problems (Geoblock/Countryblock)
Very satisfied with Yesim and will use this app again in the future.
Turkish Riviera - Antalya - Belek
15GB Option used.
Used: May/June 2025”
“The next used eSIM during my 15-day stay in Turkey is the Yesim eSIM.
3GB Option for 30 days. ('Balkans-Region-Option' due to promo)
This worked fine as well.
Activation without any troubles.
In the region where I was, Turkish Riviera, I could only connect to Turk Telecom with 4G-speed. When trying manually to connect to other networks, this was not possible. Maybe that is just a local setting and may not be the case in other places in Turkey.
After using Vodafone with my previous eSIM, the now used Turk Telecom was perfectly working. The speed was roundabout the speed of Vodafone, did not feel any difference when using the internet.
Speed test as per below.
I would recommend to use the Yesim eSIM in Turkey.
Used: May 2024”
Yesim offers unlimited‑data eSIM plans for Turkey. The plans are available in different validity periods – 1 day, 7 days, 15 days and 30 days – with prices starting at $8.05 for a 1‑day pass and going up to $54.05 for a 30‑day pass. All of these plans are listed as unlimited, but the description notes that speeds “may be throttled” after heavy usage, reflecting a Fair Usage Policy. Travelers who are concerned about potential speed restrictions are advised to contact Yesim directly to verify whether the FUP applies and what the typical data bandwidth at normal speed is.
Yesim does not provide eSIM plans for Turkey that include a phone number or SMS service. All available plans from Yesim for Turkey are data‑only; they do not support inbound or outbound calls or text messages. Travelers who need voice or messaging can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.
Yesim lists 8 single‑country data plans and 22 multi‑country plans for Turkey. The plans cover data transfers ranging from 500 MB up to unlimited, with prices from about $0.57 to $125.34. Single‑country plans focus solely on Turkish usage, while multi‑country options provide additional coverage in multiple regions. The validity of the plans spans from one day to a full year, and the data caps vary across the portfolio, offering both fixed‑amount packages and larger or unlimited options.
