Perfect
After a first trial in Montenegro a few years ago, we used GoMoWorld again this year in Turkey — another great success! We bought two eSIMs, one for me and one for my husband, and everything worked perfectly. I highly recommend GoMoWorld. Thank you so much!

Recommended for travelling
So far, I've used GoMoWorld in several countries (USA, Guatemala, and Vietnam), and the coverage was good every time. It’s also consistently cheaper than other eSIM providers. Only in Mexico did we occasionally have connection issues, but I emailed them and they responded immediately with a suitable solution. I’m very happy with the service GoMoWorld offers and would recommend them to everyone.
