Global eSIMs in our catalogue cover 99 to 174 countries and cost $2.51 to $8.20 per gigabyte, several times more than a regional plan. They are worth it for trips that hop between continents with short stops. For the most common long trips there are cheaper middle options: Europe, Asia and USA covers 81 countries with 10 GB for $19.04, and Half Global covers Europe and the US with 12 GB for $11.40.
A worldwide eSIM sounds like the obvious buy for a big trip: install once, forget about borders. The catch is the price per gigabyte, and the fact that “global” means a list of countries that differs from plan to plan. We compared every plan in our catalogue covering 50 or more countries on 5 October 2026, and checked them against common routes.
- Widest coverage: Best World, 174 countries, from $8.20 for 1 GB.
- Cheapest way in: Global Special, 133 countries, $6.50 for 1 GB over 7 days, with data exiting in the UK.
- Best value for Europe, Asia, Australia and the US: Europe, Asia and USA, 81 countries, 10 GB for $19.04, or $1.90 per GB.
- Best value for Europe and the US: Half Global, 52 countries, 12 GB for $11.40, or $0.95 per GB.
The worldwide plans compared
| Plan family | Countries | From | Best per GB | Data exits in | Starts |
|---|---|---|---|---|---|

| Discover Global | 157 | $6.60 for 1 GB, 7 days | $3.23 (10 GB, 30 days) | Not published | First use |
| Global Special | 133 | $6.50 for 1 GB, 7 days | $3.21 (20 GB, 365 days) | UK | First use |
| Global | 99 | $39.76 for 13 GB, 365 days | $2.58 (26 GB, 365 days) | Hong Kong | When installed |
| Europe, Asia and USA | 81 | $4.00 for 1 GB, 14 days | $1.46 (40 GB, 365 days) | UK | First use |
| Half Global | 52 | $11.40 for 12 GB, 30 days | $0.75 (36 GB, 30 days) | Hong Kong | When installed |
All six list hotspot as supported. The four widest families include mainland China, Japan, the US, the UK, Australia, Brazil and South Africa. Europe, Asia and USA leaves out mainland China, Canada, Mexico, Brazil, South Africa and the UAE. Half Global covers the EU, the UK, Switzerland, Norway, Turkey, the UAE, the US and parts of Central Asia, but not East Asia or Australia.
Global vs one plan per region
Here is a common round-the-world shape: two weeks in Europe, then a week each in Thailand, Japan and Australia, five weeks and about 20 to 25 GB in total. The plan has to last 35 days, which rules out the 30-day multi-region plans.
| Approach | What you buy | Total |
|---|---|---|
| One worldwide plan | Best World 25 GB, 90 days | $62.72 |
| One multi-region plan | Europe, Asia and USA 20 GB, 365 days | $36.18 |
| One plan per region | Europe 10 GB $7.54, Thailand 10 GB $7.00, Japan 5 GB $5.30, Australia 5 GB $5.20 | $25.04 |
Per-region plans are the cheapest but mean four installs and four switches. A multi-region plan is one install for a moderate premium. A worldwide plan costs the most and only pays off if the route is unpredictable or touches many regions briefly. For Europe plus the US, the gap is wider: Half Global’s 12 GB for $11.40 covers both, while a worldwide plan of similar size costs three to four times as much.

When a global eSIM is the right buy
- Many short stops across continents: a business trip through Singapore, Dubai and São Paulo, or a cruise with ports on three continents.
- Layovers: one global plan keeps you online in every transit airport without buying a plan per country.
- An unpredictable route: if you do not know where you will be next week, coverage matters more than price per GB.
- Light use: at 1 to 3 GB, the absolute price difference is small. Global Special 1 GB for 7 days is $6.50.
For long stays in one or two regions, a regional plan is cheaper; see the cheapest Europe eSIM or Asia regional vs country plans.
Three things to check on any global plan
- The country list, not the name. “Global” ranges from 52 to 174 countries in our catalogue. Check every stop, including transit countries. Our coverage guide shows how.
- When the clock starts. The Global and Half Global plans start when installed; the others start on first data use. See when an eSIM starts counting.
- Where data exits. If your route includes mainland China and you need ChatGPT, Global Special exits in the UK; the Global plan exits in Hong Kong. Our China eSIM without a VPN page explains why that matters.
Frequently asked questions
What is the best global eSIM?
It depends on the route. Best World covers the most countries, 174. Global Special is the cheapest entry at $6.50 and exits in the UK. For Europe, Asia, Australia and the US, Europe, Asia and USA is cheaper per GB at $1.90 for 10 GB, on 5 October 2026.
Is a global eSIM cheaper than buying one per country?
Usually not. Worldwide plans cost $2.51 to $3.23 per GB at their best size, while single-country and regional plans often cost $0.60 to $1.00. A global plan saves installs and switching, not money, unless your trip is a string of short stops.
Which global eSIM covers China?
Best World, Discover Global, Global Special and the Global plan all include mainland China. Europe, Asia and USA and Half Global do not. If you need ChatGPT in China, choose Global Special, which exits in the UK; the Global plan exits in Hong Kong.
What is the cheapest eSIM for Europe and the USA together?
Half Global: 12 GB for 30 days at $11.40, covering the EU, the UK, Switzerland, Turkey and the US among 52 countries. It starts counting when installed. Europe, Asia and USA is the alternative that starts on first use, from $10.70 for 5 GB.
Does a global eSIM work in every country?
No. Even the widest plan in our catalogue lists 174 countries, and coverage differs between plans: Half Global, for example, has no East Asian countries. Always check the plan’s country list against every stop and transit airport on your route.
Can I use hotspot with a global eSIM?
Yes. All six global and multi-region families compared here list hotspot as supported. Hotspot uses the same data allowance, and global data is expensive per GB, so for heavy tethering a regional plan in the country where you work is usually cheaper.
A global eSIM is a convenience product. Buy it when convenience is what you need; for everything else, the right regional plan gets you the same coverage for less.
