What each criterion measures
| Criterion | What earns a high score | Where we read it |
|---|---|---|
| Unlimited coverage | Many countries with an unlimited option, plus regional unlimited plans | Plan lists and country pages |
| Price per day | Low price for a day and for a month on popular destinations | Checkout prices where published |
| Plan length choice | Short plans for short trips and enough steps to avoid paying for unused days | Plan length options |
| Daily full-speed quota | A large, published daily allowance and a usable speed after it | Fair usage and plan details |
| Hotspot rules | Sharing allowed, no tight separate cap, rules written down | Plan details and help pages |
| Ways to buy and pay | Several apps or channels, card and non-card payments, simple purchase | Homepage, store listings, terms |
The full reasoning, including what lowers a score, is in how we score.
The ranking, provider by provider
TonMobile
Unlimited in 130+ single countries. Best for: one-country trips of any length, from a single day to a month.
TonMobile has the widest list of countries with an unlimited option among the providers we compared, and six plan lengths starting at one day. A day in the UK, France or Spain starts at $3.10. The catch is the daily full-speed quota: the plan cards we read showed 1 GB a day, then 512 kbps, so heavy streamers should check the card for their country first.
Pros
- Unlimited plans in more than 130 countries
- Plans from 1 day, no rounding up to a week
- Card and crypto checkout, no documents asked
- Telegram bot, web app, iOS and Android
Cons
- Unlimited works in one country only, regional packs are fixed GB
- Daily full-speed quota on the cards we read is 1 GB
- Hotspot depends on the local carrier and phone
- Data only, no local number
Saily
5 GB a day with open hotspot. Best for: travelers who share data with a laptop every day.
Saily says its unlimited plans give 5 GB of high-speed data in each 24-hour period, then 1 Mbps, and that hotspot sharing is unlimited on every plan. Coverage is narrower: 62 countries plus two regional packs, with plan lengths from 5 to 30 days.
Pros
- Large 5 GB daily quota
- Hotspot sharing not capped separately
- Regional unlimited for Europe (35 countries)
Cons
- Shortest plan is 5 days
- Unlimited country list about half of TonMobile's
- Only a 'from' price is shown on its unlimited overview page
Airalo
Clear 3 GB daily rule. Best for: people who want the speed rules spelled out.
Airalo publishes a simple rule: 3 GB of high-speed data per 24 hours from activation, then 1 Mbps. Tethering is allowed with no extra cap, but shared data comes out of the same 3 GB. Unlimited plans exist for many countries and for Europe, Asia and Latin America.
Pros
- Published daily quota and slowdown speed

5 GB a day, 2 Mbps after. Best for: remote workers on daily video calls.
On the Ubigi unlimited plan we read (Egypt, 30 days, $69), the first 5 GB each day run at full speed and the rest at 2 Mbps, the fastest fallback in this list. Unlimited is offered in selected countries only.

Nomad

How often this changes
Unlimited plans, quotas and prices change without notice. We re-read provider pages when we update this table, and the date on this page shows the last full check.
For the reasoning behind daily quotas and slowdown speeds, read the unlimited eSIM guide or the note on what still works after the cap.
Questions about these scores
Why is TonMobile first if its daily quota is smaller?
Quota is one of six criteria. TonMobile scores lower there but leads on coverage, short plans, price per day and payment options, which outweigh it in the average. If quota matters most to you, Saily or Ubigi are the stronger picks.
Did you buy and test each plan?
No. The scores are built from published plan terms, prices and help pages, not from speed tests. Real-world speed depends on the local network and signal.
Can a provider pay to rank higher?
No. Positions are set by the scores. Scores are built from the same six criteria for every provider, so a provider cannot change its own position.
How is the overall score calculated?
It is the simple average of the six criterion scores, rounded to one decimal. There is no hidden weighting.
Why is a provider I use missing?
We include providers whose unlimited plans and rules we could read on their own pages. We add more when their terms are clear enough to score fairly.
How often are the scores updated?
Whenever a provider changes a quota, price or plan list that affects a score, and at least with each scheduled review of the site.
