Glowi or Holafly for Thailand: the short answer

The maths, for one week

For a week, Holafly’s plan costs €25.50 for unlimited data. For less money than that, Glowi gives you 20 GB (€17.95). That’s 2.9 GB a day.

That’s more than most people use on a trip: maps, messaging, social media and some music don’t get anywhere near it. Unless you watch video every day, Glowi is cheaper in Thailand.

The prices, side by side

Holafly Thailand — unlimited data

Holafly prices checked on their website on 18 September 2026. Prices change: if you spot a difference, send it to us and we’ll correct it.

Glowi Thailand — counted gigabytes, valid for up to 30 days

Prices from this website, VAT included, in the currency you’ve chosen. They come from the same catalogue as the Thailand page, so they can’t go out of date here.

Holafly’s prices are shown in euros, whatever currency you’ve chosen: that’s how Holafly publishes them on the page we checked, and it isn’t our place to convert them. Ours appear in your currency, exactly as on the Thailand page. Where we work out a difference or a saving, we do it in euros.

The small print that does matter: the hotspot

This is written on Holafly’s website, and hardly anyone reads it:

“Share 1 GB of data a day with family, friends or travel companions.”

In other words: what they sell as unlimited is unlimited for your phone, but what you share through the hotspot is limited to 1 GB a day. On a 7-day plan, 7 GB in total.

If two of you are travelling and sharing one phone’s connection, that “unlimited” is in practice 1 GB a day for the second phone.

And that “unlimited” on the phone isn’t unconditional either: Holafly mentions a “Fair Use Policy” that can apply “for a period of no more than one (1) day” (our translation), but doesn’t publish how many GB trigger it. That’s what can be verified: that they mention it and that the threshold isn’t published. We don’t know whether it’s applied, or when.

With Glowi the gigabytes are yours to share however you like: there’s no separate counter for the hotspot. And there’s no fair use policy on top: the gigabytes you buy are the gigabytes you use.

How many GB do you really need?

Don’t trust anyone’s published averages, ours included. Check on your own phone: it’s the only figure that counts.

• iPhone: Settings → Mobile Data → scroll down to “Current Period”.
• Android: Settings → Connections → Data usage → Mobile data usage.

Look at what you used last month at home and take off what you’ll do on hotel Wi-Fi. When travelling, people use maps, messaging and some social media; what sends usage soaring is video.

And if you’d rather do the maths before choosing a plan, we’ve done it: how many GB you need for a trip, with what each thing uses and where every figure comes from.

If you want to understand why an “unlimited” plan isn’t what it seems, we explain it all in Unlimited data eSIMs: what they don’t tell you.

What usually isn’t published: how your connection is routed

The exit country matters more than it seems, and here it’s worth knowing before you buy: in Thailand your traffic doesn’t exit through Thailand: it exits via Singapore. When it exits somewhere else, some services will treat you as if you were there: online banking may ask for extra verification, and your streaming catalogue won’t be the one you get at home.

It isn’t an advantage and we won’t sell it to you as one. It’s a fact, and we publish it anyway: it’s what you need to know before you pay, not after.

We publish this on the page of every one of our destinations. It isn’t usual in the industry.

When Holafly is the better choice

Honestly, because a comparison where the author always wins is worthless:

• If you’ll use more than 20 GB in a month. Beyond that their plan pays off and ours falls short.
• If you don’t want to think about gigabytes. Paying extra so you never have to watch a counter is a perfectly good reason.
• If you’re travelling for less than a week and use a lot. Their 3-day plan at €11.37 competes well with heavy, concentrated use.

And where we’re the same: neither includes a phone number. Both are data only, and calls go over WhatsApp or similar.

How we made this comparison

• Holafly’s prices come from their website, in euros, checked on 18 September 2026. Prices change: if you spot a difference, send us theirs and we’ll correct it.
• Ours are the ones on this website, VAT included, and come from the same catalogue as the Thailand page.
• Network, operator, exit country and APN details come from our wholesale provider’s technical sheet, plan by plan.
• The two Holafly quotes — the hotspot and the “Fair Use Policy” — are taken word for word from their Spanish product page and translated by us. On the second, we only say what can be checked: that they mention it and that they don’t publish how many GB trigger it.
• The 20 GB threshold isn’t an opinion: it’s our plan with the most gigabytes that costs less than their 7-day plan. The build works it out with both catalogues in front of it.

We don’t compare speed because we have no measurements of our own, and claiming to be “the fastest” without measuring it would be exactly what we criticise.
