Who is Simbye ? A look at the travel eSIM provider
Simbye is a travel eSIM provider : the principle is that of a digital SIM. You download an eSIM profile via QR code and are connected on arrival, with no roaming fees and no physical SIM card to insert. The plans rely on partner networks in each destination.
The Simbye catalogue holds 643 active plans covering 129 countries. Depending on the destination, the plan relies on the locally chosen MVNO or operator, which makes 4G/5G speeds and conditions vary from one country to another. The vast majority of offers are fixed-volume data plans.
The catalogue covers short trips (small volumes over a few days) as well as longer stays. Fixed-volume plans suit controlled usage (browsing, maps, messaging, social media) ; for a need for unlimited data, it is still worth comparing with specialised alternatives.
Simbye is present on the major tourist destinations : Europe, the United States, Japan, Thailand, Turkey, the UAE, plus many countries in Asia, Latin America and North Africa where the travel eSIM is a strong replacement for local SIM cards and classic carrier roaming.
Is Simbye reliable ? Simbye shows a 4.1/5 rating on Trustpilot, on one of the largest review volumes in its category. This fair rating, in a mid-to-high range, and this relatively large review volume give a more solid signal than an isolated score. The points to watch are those common to data eSIMs : speed depends on the partner network of the country, plans are data only (no classic calls or SMS), and you should check your phone's iPhone / Android compatibility before buying.
Simbye reviews : what do users say ?
Datadopt aggregates ratings from public review platforms to give you an objective view of Simbye's reputation. The available source is Trustpilot :
Trustpilot
4.1/5
62 reviews
Recurring strengths
- Simple, fast purchase and QR code installation
- Well-stocked catalogue of plans covering 129 countries
- A fair rating, backed by one of the highest review volumes in the sector
- Good coverage of flagship tourist destinations
Points to watch
- A 4.1/5 rating that stays in a mid-to-high range, without being excellent
- Only one public review source available (Trustpilot)
- Speed varies with the partner network of the country visited
- Data-only plans : no classic calls or SMS
Our take : Simbye is a relevant choice for anyone looking for fixed-volume eSIM plans over broad coverage, with a solid Trustpilot rating and the largest review volume of the batch. For a very specific need for unlimited data or a much larger brand catalogue, the alternatives Holafly, Airalo or Nomad are also worth comparing.
Simbye coverage : where do the plans work ?

Popular covered destinations
⚠️ Countries with restrictions (China, etc.)
In countries that filter the web (China and its Great Firewall in particular), Google, WhatsApp, Instagram and Facebook may stay blocked even with an eSIM, because access goes through a local operator. To keep your usual services, install a VPN (NordVPN, ExpressVPN, Proton VPN) before departure. Always check your destination's availability in the plan list above.
