Best Travel eSIM 2026: Airalo vs Holafly vs Saily Compared

Updated April 2026 7 min read

Travel eSIMs have become the default way to stay connected overseas. But with dozens of providers, choosing one feels harder than it should. Most comparison sites just list features without telling you which one to actually buy.

This guide compares the three biggest providers: Airalo, Holafly, and Saily. We look at pricing, coverage, data policies, and customer support to help you decide.

Airalo: best overall coverage and flexibility

Airalo is the largest eSIM marketplace with coverage in over 200 countries and regions. Plans are data capped (you buy a set amount of GB) and priced competitively. They also offer regional and global plans for multi country trips.

Strengths:

  • Widest country coverage of any provider
  • Flexible plans from 1 GB to 20 GB with varying validity periods
  • Top ups work on most plans without reinstalling the eSIM
  • Regional plans cover multiple countries on one eSIM (e.g. Asia, Europe)
  • Well established with a large user base

Weaknesses:

  • No unlimited data option
  • Pricing is in USD, which means currency conversion fees for non US buyers
  • Support response times can be slow during peak periods

Best for: Most travellers. Especially those visiting less common destinations, doing multi country trips, or wanting to pay only for what they need.

Holafly: best for unlimited data

Holafly's entire model is built around unlimited data plans. You pick your destination and trip length, pay a flat fee, and get unlimited data for that period. No worrying about running out.

Strengths:

  • Unlimited data removes anxiety about running out mid trip
  • Simple pricing: one price per destination per day
  • Good for heavy data users, remote workers, and content creators
  • WhatsApp support is responsive

Weaknesses:

  • Most expensive option. A 14 day plan can cost $47 to $84 USD depending on destination
  • Some users report throttling after high daily usage (reports suggest 500 MB to 1 GB/day in some regions)
  • No top ups. If your plan expires, you buy a new one
  • Fewer countries than Airalo
  • "Unlimited" has fine print. Some destinations are fair use only

Best for: Heavy data users who value peace of mind over cost. Remote workers, video callers, and people who stream regularly while travelling.

Saily: best budget option for simple trips

Saily is backed by Nord Security (the company behind NordVPN). It launched more recently and positions itself as a clean, simple eSIM option with competitive pricing.

Strengths:

  • Competitive pricing, often slightly cheaper than Airalo on mid range plans
  • Clean, minimal app with easy setup
  • Backed by a large, well funded tech company
  • Top ups supported on most plans

Weaknesses:

  • Fewer countries covered (~150 vs Airalo's 200+)
  • Limited regional and global plan options
  • Newer provider with a smaller user base and less track record
  • Support is email only, no live chat

Best for: Budget conscious travellers visiting popular destinations who want a simple, no frills experience.

Which one should you choose?

The short version

Airalo for coverage and flexibility. Holafly if you need unlimited and do not mind paying for it. Saily for budget trips to common destinations. Travelren if you want Airalo coverage with AUD pricing and Australian support.

For most Australian travellers, the decision comes down to this:

  • If you want the cheapest per GB price: Airalo or Saily. Both offer competitive data capped plans
  • If you are visiting an uncommon destination: Airalo. It covers 50+ more countries than the alternatives
  • If you absolutely need unlimited data: Holafly. Nobody else offers it. Just be aware of the fair use throttling
  • If you want AUD pricing and local support: Travelren. Same Airalo network and plans, priced in Australian dollars
  • If you are visiting multiple countries: Airalo or Travelren. Regional plans (Asia, Europe) cover multiple countries on one eSIM

A note on "best eSIM" lists

Most "best travel eSIM" articles are affiliate content where the ranking is determined by commission rates, not product quality. We have tried to be genuinely useful here. Airalo and Holafly both have strengths. Saily is a solid newer option. The right choice depends on what you value: price, coverage, simplicity, or unlimited data.
