eSIM versus roaming
In Turkey a typical Czech roaming bundle is 199 CZK per 500 MB a day. Ten days at 700 MB a day comes to 3 980 Kč. An eSIM for the same trip is one plan, not a daily surcharge.
Europe is a different case
With a Czech SIM, the EU is roam-like-at-home. An eSIM pays off when the data cap is too small, the SIM is from outside the EU, or you want work data kept apart from personal data. The UK and Switzerland are outside EU roaming, so an eSIM pays off there much as it does in Turkey.

FAQ
When is an eSIM a poor deal inside the EU?
When you have a Czech SIM and plenty of data left in the plan. Inside the EU you roam like at home, so extra data costs the same as in Czechia. An eSIM makes sense with a small cap, a non-EU SIM, or when you want work data kept separate.
What does roaming in Turkey cost?
Turkey is outside the EU. A typical Czech daily bundle is 199 CZK per 500 MB. Ten days at 700 MB a day comes to 3 980 Kč, before you watch any video.
Do I lose my number with an eSIM?
No. A data eSIM is data only. You leave the plastic SIM in the phone, so calls and texts stay on your number.
