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.
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

Only data‑only eSIMs are sold by the provider for Turkish travelers, so there is no inbound or outbound voice or SMS service included. Travelers who need to communicate can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.
