Ratings and reviews

You should be able to just press an activation button. Having trouble activating with QR code on android. Tried downloading to photos and scanning from there did not work also having problems copying and pasting manual code. I don't have another device to send it to.

the best I've had travelling to Turkey.. easy to install and very good value 👌🏼

This is the first time I used ohayu eSIM. purchaes esim on 22 Nov 2025 for Turkey and got charged for 20.49 us doller , as soon as I arrived,I tried to get my esim working but no matter what I did ,it did not work until I left Turkey on 4th December. It means I did not use my esim and I am asking for my money back. I don't know if this is the proper channel but this review is the only way I could find to contact Ohayu esim.Thanks
