Reviews & ratings
FastEsim support was very fast and helpful via WhatsApp. Excellent responsiveness and team availability to answer my questions.
The team responded quickly and helped me set up the settings so everything worked properly. Impressive customer service.
The 4G signal with this SIM is so slow I can't work abroad. The price is way too high for what you get.

What is FastEsim?
What is FastEsim?
FastEsim is an eSIM (Embedded SIM) provider specializing in mobile connectivity solutions for international travelers. The platform allows access to high-speed internet in over 200 destinations without having to buy a local physical SIM or pay high roaming fees.
The FastEsim app offers three types of plans: local plans (covering a single country), regional plans (covering multiple countries in one region), and global plans (covering multiple continents). Each plan offers different data amounts and validity periods, from pay-as-you-go to unlimited subscriptions, suited to all traveler profiles.
The activation process is extremely simple: after purchasing a plan via the app, a QR code is generated and sent by email. The user scans this QR code directly in the settings of their eSIM-compatible device to install the profile. Upon arrival at the destination, just activate the eSIM and have high-speed internet connection. FastEsim operates without contract, without automatic renewal, and with a guaranteed refund policy if needed.
