Airalo vs Nomad: two by-GB models compared

Airalo and Nomad are two of the best-known travel eSIM apps, and they work in a similar way: you buy a data package for a country or region, install a QR code, and the data runs down until it's gone. The real difference sits in the fine print of their "unlimited" tiers.

This page is a model comparison, not a speed test. We don't quote either brand's prices or ratings — those change weekly and you should check them in their own apps. What we can compare is how each structure works, and where a truly unlimited eSIM makes more sense.

How Airalo and Nomad actually work

Both are app-first eSIM stores. You pick a destination, buy a data bundle, scan a QR code (or install in-app), and your phone connects to a local partner network when you land. Neither gives you a phone number — it's data only, so WhatsApp, iMessage, maps and app calls work, and your home SIM keeps your number.

Airalo (Singapore) is the bigger catalogue, with local, regional and global packages sold by GB. Its "unlimited" plans ship with 3 GB/day of high-speed data by default, which may vary by package; after that the line drops to about 1 Mbps for the rest of the 24-hour window. Tethering counts toward the same cap.

Nomad works the same way, with by-GB bundles and "Unlimited" tiers that carry about 2 GB/day of high-speed data on most plans, then roughly 1-2 Mbps. Nomad's own help center is blunt about it: those plans do not offer unrestricted high-speed data.

Both publish their terms openly. Read the specific package page before you buy — caps differ by country.

Airalo vs Nomad: the decision points that matter

If you're a light user — email, maps, a few messages, some scrolling — either brand is fine and a small by-GB package is often the cheapest thing you can buy. The daily cap never becomes a problem because you never reach it.

The decision flips if you stream, upload video, work from the road, or travel with a family all pulling from one line.

When Airalo or Nomad is the better pick

We'd rather be honest than pushy. Choose one of them when:

• Your trip is to a destination we don't cover. VoaSim has no coverage in the island Caribbean (Dominican Republic, Cuba, Jamaica, Bahamas, Aruba, Curaçao). Puerto Rico works, because it runs on US networks.
• You need very little data. A 1 GB or 3 GB bundle for a weekend can cost less than any unlimited plan, anywhere.
• You want a top-up-as-you-go app and like managing data balances.
• You want a specific local carrier listed in their catalogue.

Check the current packages at airalo.com and nomadesim.com — prices and caps move, and only their own pages are authoritative. If you want a neutral side-by-side of unlimited plans, our eSIM Price Index tracks VoaSim, Holafly, Airalo and Nomad daily and separates plans with and without a daily high-speed cap, with the method published.

Where VoaSim fits: truly unlimited, price by destination and trip length

VoaSim exists for the traveler who doesn't want to think about gigabytes. Our eSIM has no data cap, no speed throttling and no hidden fair-use clause. You pay for days, not data.

Price set by destination and trip length. Today's prices include a 15% promo:

Coverage reaches 160+ destinations on every continent, and the Europe plan covers 39 countries with one eSIM, including Switzerland, the UK, Turkey, Norway and Iceland. Trips of 1-4 days pay the 5-day package; maximum 90 days per eSIM. See all destinations.

Hotspot, honesty and the rules you should know

One rule we state up front: VoaSim does not allow hotspot or tethering. If you share the connection, the local carrier may block the line. Each traveler uses their own eSIM — add a second eSIM to the same order and it gets an extra 10% off. Airalo allows tethering but counts it against the same daily cap, so neither approach gives you a free unlimited router.

Other honest limits: no phone number and no traditional voice calls (data only). Cruises work on land, in ports, not at sea. Your phone must be unlocked and eSIM-capable — iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer, and most phones from 2020 on. Dial *#06#; if an EID appears, you're good. We don't sell physical SIM cards.

Days start counting at the eSIM's first connection at the destination, so install at home and keep the line off until you land.

Buying, support and the safety net

Checkout is in USD by international credit or debit card through Stripe, with no hidden fees and an invoice by email. The QR code arrives by email within minutes — plus a WhatsApp heads-up if you leave a number — with step-by-step install guides for iPhone and Android.

Support is human, by chat or hola@voasim.com. If the eSIM won't connect and our team can't fix it, you get a 100% refund. We also run a free diagnostic tool, eSIM Rescue, that troubleshoots an eSIM with no signal — including one you bought from Airalo, Nomad or anyone else.
