TL;DR

Install the travel eSIM before departure, then set it as the primary line for mobile data and enable data roaming after arriving in Istanbul. You can turn off your home SIM before the flight to avoid roaming charges.

You can install the eSIM before travelling; after landing in Istanbul, set it as the primary line for mobile data and enable data roaming on that eSIM.

Activating an eSIM before the trip is not necessarily a problem: after arrival, turn off airplane mode, enable cellular service, and select the installed eSIM for mobile data.

To avoid unexpected charges, you can disable your home SIM, such as Megafon, before departure and use only the travel eSIM in Istanbul.

A practical sequence is to install the eSIM following its instructions before travel, temporarily switch it off if needed, then enable it in Turkey and route mobile data through it.
