A free trial answers one question: does this network work here

The largest free allowance we track is 1 GB. The smallest is 100 MB. Neither is a travel plan, and reading them as one is how people end up stranded on day two.

What a trial does well is prove that a provider's local partner network actually carries a signal where you are standing, before you commit money to a two week plan on the same network.

One gigabyte covers about two days of careful use

Rough figures, assuming you are not streaming:

  • Maps with turn by turn navigation costs roughly 5 MB per hour.
  • Messaging with photos runs about 10 MB to 20 MB a day.
  • Email and web browsing costs around 50 MB an hour.
  • A short video call costs 300 MB or more an hour, which is why 1 GB disappears into one call home.

So 1 GB covers maps, messages and bookings for two or three days. It does not cover video, hotspotting a laptop, or social feeds with autoplay left on.

Under three days, a trial can genuinely be enough

A weekend city break where you need maps, a ride hailing app and a restaurant booking fits inside 1 GB if you download offline maps before you go.

Nomad's 1 GB over 3 days is the closest thing to a usable short trip allowance among the providers we track. Pair it with offline maps and it holds.

Past three days, buying is usually the cheaper mistake to avoid

Beyond a long weekend, the trial runs out somewhere inconvenient and you buy a plan anyway, at whatever price you can find while standing in the street on a dying connection.

Buying the plan before you travel costs the same money with none of that. Use the trial first to check coverage, then buy on the provider that worked.

Stacking trials across providers is possible and fragile

Claiming a trial from three providers gives you more total data than any single trial. It also gives you three apps, three accounts and three validity windows running at once.

Most offers are restricted to new customers and one per account or device, so this works once per provider and not repeatedly. It suits a short trip where you want redundancy more than volume.

The real cost of a free trial is the conditions attached

Free trials cost nothing in money and something in commitment. GigSky's 7 day window wants a card set as your default payment method. Firsty's ongoing free data wants you to watch adverts every few hours and accept heavily reduced speed. Roamless gives credit rather than data, so what you get depends on local rates.

None of those are traps, and all of them are the sort of thing worth knowing before you are relying on the connection. The comparison table states the condition for every provider.

Providers with no trial are not automatically worse

Saily and Ubigi have no free trial at all. Holafly bundles its 1 GB into paid plans rather than offering it standalone. Airalo ended its open trial in 2025 and the remaining welcome credit is a Mastercard cardholder benefit.

That tells you nothing about whether their networks are good. It tells you that testing them costs the price of the smallest plan, which is often a few dollars and sometimes the better decision for a long trip.

How to decide in one pass

Use a free trial when the trip is under three days, when you want to test a network before committing, or when you need a safety net on arrival while you sort out something larger.

Buy a plan when the trip is longer than a long weekend, when you need to hotspot, or when being without data would cost you more than the plan does.
