eSimy

eSimy specializes in unlimited data, so there's no per-GB rate to track or worry about burning through a pool too fast. You get access to Turkcell and Türk Telekom at starting prices around €1.49, with genuinely unlimited usage for the plan period. The service launched in 2019 and has built a focused reputation on this single, simple offer: pick your network, get unlimited data.

This appeals directly to travelers who spend a lot of time on maps, video calls, or streaming while traveling, and don't want to ration data. The simplicity cuts down decision fatigue, and you'll never hit a surprise overage charge or see your plan evaporate mid-trip because you watched a few extra hours of content.
