Round by round
Lower sticker price for the same data tier. The 30-day window is generous for moderate users.
Priced above the competition here, though pricing is only one piece of the puzzle.
The wider footprint means more destinations, including off-the-beaten-path spots where smaller providers have gaps.
Narrower coverage, though the destinations it does cover tend to have strong local network partnerships.
Rated higher for speed, based on published carrier partnerships and 5G network share across the destinations we reviewed.
Rated lower for speed, based on published carrier partnerships and 5G network share, but real-world usability is fine for standard travel tasks.
No unlimited tier. If you run out, you buy a top-up. Fine for most travelers, frustrating for power users.
Capped data only. Budget-friendly if your usage is predictable, but no safety net for heavy days.
Responsive and helpful when things go wrong. The support experience gave us confidence for mid-trip issues.
Adequate support, though you may wait longer for a reply compared to the competition.
Clean interface, fast activation flow, and intuitive data monitoring. The day-to-day experience is polished.
The app works fine, but navigation and account management could be more refined.

Our verdict
Airalo is the better default. For most readers making a straightforward trip, Airalo will be the right call. It wins on the metrics that matter day-to-day: pricing, coverage, and app experience.
GigSky is the better specialist. If you value what it does best, even though GigSky did not win a single round in this matchup: its strength here lies outside what we score head-to-head.
Either way, you cannot make a truly bad choice. Both providers clear our recommendation bar, and both will keep you connected reliably abroad. The right one is the one that matches how you actually travel.
Similar coverage, almost double the price for GigSky's data.
HelloRoam is eSIMRated's Editor's Choice at 4.9/5 overall. Airalo and GigSky cover nearly the same ground, 200+ countries against GigSky's 190, so coverage is not what decides between them. Price does: Airalo's 5 GB, 30-day plan costs $16.00, GigSky's costs $30.00 for the same size and duration, working out to $3.20/GB against $6.00/GB. Airalo's pricing rating reflects that gap, scoring 4.2/5 against GigSky's 3.6/5, the lowest pricing score of the two. GigSky's case is a narrow one: Apple Watch eSIM support, a feature Airalo does not offer, plus day passes for a short visit and enterprise plans for business travel. If you need a cellular Apple Watch plan or a one-day pass, GigSky covers a gap Airalo leaves open. For a phone-only trip at any length, Airalo's lower price and 4.7/5 app score make it the more practical pick.
Also worth considering
HelloRoam scores 4.9/5 in our ratings, higher than both Airalo (4.5/5) and GigSky (4.1/5). It covers 185 countries starting at $1.14/plan with 24/7 WhatsApp support.
