3 stars: Login in English doesn't work. Workaround: Set it to turkish, login, then switch back to English.
3 stars: Unfortunately, this app. services is not fully in English, I face difficulty to get the full services.
2 stars: I've been struggling with this login error of the English version as many of those who shared their reviews here. Hopefully, I used the workaround from one of the reviews to make first login in Turkish, accept terms, and then switch to English. It work for me now. Thank you, guys. By the way, the guy in store couldn't solve the issue. Turkcell, please at least share the workaround with your staff, so they can help customers.
2 stars: English version is unworkable, I cannot buy packets, I see only variable names on the buttons instead their values, and buttons don't work at all. And almost everything except some buttons is in Turkish, not only images, but most texts. Why do you have EN version then?
