Traveller Reviews
Yesim has become my standard travel prep for every international trip. Purchased a Japan eSIM the night before departure, activated on the plane before landing, and had instant 4G coverage from the moment I walked out of Narita. Saved at least $80 vs my carrier's roaming charges for a 10-day trip. The app interface is clean and data usage tracking is accurate.
Great eSIM service that genuinely delivers. Used across EU, Thailand, and UAE in the same year with no major issues. The EU regional plan was excellent value covering 30+ countries on one plan. Speeds were 4G throughout except one rural area. The one-time setup via QR code is simpler than I expected even for someone not particularly technical.
As a digital nomad Yesim is essential infrastructure. The speed and reliability has been excellent across Asia and Europe. Renewing plans mid-trip through the app is seamless. The pricing beats local SIM cards in most expensive markets like Switzerland, Singapore, and Japan. Support responded within an hour when I had a question about plan top-up.
