When it comes to working and living abroad, you're always going to need a fast and steady internet connection — and fiddling around with local SIMs and data hotspots is rarely worth the effort. It's why more and more digital nomads and international travellers are switching to eSIMs. They're quick, easy, and affordable to set up, with no risk of shock roaming fees when you get home.
But there are several eSIM providers now operating in this space. In this guide, we compare three of the biggest — SIMOVO, Holafly, and Saily — to help you work out which one suits your travel style best.
The eSIM boom: what's driving it
The global eSIM market is set to grow from $1.46 billion to $6.29 billion by 2032 — driven by the same forces: digital nomadism, international remote work, and the growing frustration with traditional SIM cards and roaming charges.
SIMOVO, Holafly, and Saily have all emerged as leading options in this space. Here's how they compare.
The three providers compared
[numbered title="SIMOVO" pill="Country, regional, and global packages — focus on affordability and flexibility"]SIMOVO breaks eSIMs into country, regional, and global packages, with unlimited data options also available for specific territories. Choose your destination and duration, purchase, scan the QR code, and the eSIM installs and activates when you land. No contract periods, upfront pricing throughout, and seamless automatic network switching for the best available connection wherever you are. Covers a wide range of compatible devices and accepts major payment methods including Apple Pay, Google Pay, Visa, Mastercard, Amex, and Discover.[/numbered] [numbered title="Holafly" pill="Strong on unlimited data — popular with nomads across diverse regions"]Holafly is one of the most recognised eSIM names in the market and leads with unlimited data packages designed for use across regions including Europe, the UAE, the USA, and Africa. It's picked up strong reviews from digital nomads and business travellers for its convenience and accessibility. Some customers report that Holafly sits at a higher price point than competitors — but its coverage and convenience support a nomadic lifestyle across varied territories.[/numbered] [numbered title="Saily" pill="200+ destinations, NordVPN-backed security — but some connectivity inconsistency reported"]Saily is developed by NordVPN and carries more built-in security features than most eSIM competitors — a meaningful advantage for travellers handling sensitive work online. It reportedly covers 200+ destinations worldwide and has been praised for easy setup and competitive costs. However, some reviewers report less consistent connectivity than alternatives, and pricing on unlimited plans can be significantly higher than SIMOVO's equivalent for the same duration.[/numbered]Pricing comparison: France as an example

The breakdown: which eSIM provider is right for you?
All three providers offer viable options for digital nomads and international travellers. Holafly and Saily both bring genuine strengths — Holafly for convenience and unlimited data coverage, Saily for security features and destination breadth.
SIMOVO's competitive edge is in affordability and flexibility. Our packages span country-specific, regional, and global plans with no contract periods and simple upfront pricing — and we've designed them so that nomads who aren't sure where they'll be from one month to the next can switch between region packages without fuss.
The best approach is to compare each provider against your specific travel pattern. If you travel to a single region frequently, country-specific plans offer the best value. If you move across multiple regions regularly, a regional or global plan simplifies everything into one purchase.
SIMOVO plans are available to browse at simovo.com — with no commitment to buy until you've checked coverage and pricing for your specific destination.

SIMOVO focuses on affordability and flexibility across country, regional, and global packages with no contracts. Holafly leads with unlimited data packages across diverse regions. Saily, developed by NordVPN, covers 200+ destinations with built-in security features. Pricing and coverage vary significantly between providers — always compare current plans for your specific destination before purchasing.[/a] [q]Are eSIMs data-only or do they support calls and texts?[/q] [a]SIMOVO eSIMs are data-only — they do not support traditional voice calls or SMS. Your existing phone SIM stays active alongside the SIMOVO eSIM for incoming calls and texts. For outgoing calls and messages while travelling, use data-based apps such as WhatsApp, FaceTime, iMessage, or Zoom. Holafly and Saily are also primarily data-only services — always confirm the specific terms of any plan before purchasing.[/a] [q]How does automatic network switching work on SIMOVO eSIMs?[/q] [a]SIMOVO eSIMs are configured to connect automatically to the strongest available local network in your destination, and switch seamlessly if better coverage appears as you move around. This means you don't need to manually select networks or worry about whether you're on the best available option — your device handles it in the background without interrupting active connections.[/a] [q]Which eSIM provider is cheapest?[/q] [a]It depends on the destination, duration, and data volume required. SIMOVO generally offers competitive pricing particularly for standard data plans, while Holafly tends to be priced higher for the convenience of unlimited data. Saily's unlimited plans can be significantly more expensive than SIMOVO equivalents for the same duration. Always compare current pricing at each provider for your specific trip before deciding — costs change regularly across all providers.[/a] [q]Can I use a SIMOVO eSIM for digital nomad work travel?[/q] [a]Yes — SIMOVO eSIMs are well-suited to digital nomad travel. Country, regional, and global packages allow you to switch between destinations without purchasing multiple separate plans. There are no contract periods and all pricing is upfront. Plans are available for most major digital nomad destinations worldwide, with automatic network switching ensuring consistent connectivity wherever you work.[/a] [/faq]
