How Much High-Speed Data Do "Unlimited" eSIMs Really Give Per Day? (2026 Data by Country)

"Unlimited" sounds simple, but almost every unlimited travel eSIM works the same way: you get a daily amount of full-speed data, and after that the plan keeps going at a slower speed until the day resets. Your data never runs out, but it does not stay fast all day either.

This matters because the daily limit, not the word "unlimited", decides whether the plan fits your trip. Below are the real numbers from the unlimited plans we sell, checked in September 2026.

How "unlimited" travel eSIMs actually work

Every unlimited plan has three parts:

• Daily full-speed allowance: the amount of data you can use at normal 4G/5G speed each day (for example 1 GB).
• Speed after the allowance: once you use the daily amount, the plan keeps working at a lower speed (for example 512 kbps).
• Daily reset: full speed comes back every 24 hours, counted from when you first used data. Your plan never stops working and never runs out.

This is called a *fair-use policy*. Mobile networks use it so a few very heavy users do not slow everyone else down. For a deeper explanation of why speeds drop, read our guide on [eSIM data throttling](/blog/esim-data-throttling-unlimited-plan-slow-speeds).

Daily full-speed limits by country (September 2026)

These are the daily limits on the unlimited plans currently sold on TripoSIM. Where a country has two numbers, there is a standard plan and a higher "Plus" plan.

Prices and limits can change. Every unlimited plan on our destination pages shows its exact daily limit under the price, so you always see it before you buy.

What can you do with 1 GB per day?

For most travellers, 1 GB of full-speed data per day is plenty. As a rough guide, 1 GB covers:

• Google Maps and navigation all day (usually under 100 MB)
• WhatsApp messages and a few voice calls (a 10-minute voice call uses about 5–10 MB)
• Instagram and social media browsing for about 1–2 hours
• Uploading 30–50 photos
• About 1 hour of video at standard quality

If you want to watch a lot of video, make long video calls, or share your connection with a laptop through hotspot, look for a "Plus" plan with 2–5 GB per day, or a large fixed plan such as 20 GB.

What does 512 kbps feel like?

After the daily limit, 512 kbps is still usable for:

• WhatsApp, Telegram and iMessage (text and photos)
• Email and basic web pages (slower to load)
• Maps that are already loaded, and ride-hailing apps
• Voice calls on WhatsApp (usually fine)

It is too slow for: HD video, video calls, big downloads, and fast social media scrolling. At 256–384 kbps (Japan, South Korea and China plans), expect messaging and email to work but most other things to feel slow until the reset.

Unlimited or fixed data: which is better for your trip?

Choose an unlimited plan if:

• You use a steady amount every day (maps, messages, social media)
• You want peace of mind that your data will never stop
• Your trip is short and you do not want to count megabytes

Choose a fixed data plan (for example 5 GB or 20 GB) if:

• Your usage is uneven, for example a lot on some days and almost nothing on others
• You need a lot of data on a single day, such as travel days with video calls or hotspot
• You want the lowest price for light use (fixed plans start from about $1–2)

A simple trick: if you expect to use more than 1 GB on most days, a fixed plan with enough total data will usually stay faster than a standard unlimited plan.

Tips to get the most from an unlimited eSIM

1. Download offline maps and playlists on Wi-Fi before you head out. That saves your full-speed data for the moments you need it.
2. Turn off automatic photo and video backup (iCloud, Google Photos) while on mobile data.
3. Set video apps to standard quality on mobile data.
4. Check the reset time. Full speed returns 24 hours after you first started using data, not at midnight.
5. Install your eSIM before you fly, on Wi-Fi. See [when to install your eSIM](/blog/when-to-install-esim-before-travel-or-after-landing).

Frequently asked questions

Are unlimited eSIMs really unlimited?

Yes and no. Your data never runs out and the plan never stops working, but only a daily amount (usually 1 GB) is at full speed. After that the speed drops until the next 24-hour reset.

When does the daily limit reset?

Full speed comes back 24 hours after you first started using data on the plan, and then every 24 hours after that. It is not tied to midnight.

Can I use hotspot on an unlimited eSIM?

Most of our unlimited plans allow hotspot, but it uses your daily full-speed allowance quickly. If you plan to connect a laptop, choose a Plus plan or a large fixed data plan.

Is 1 GB per day enough for a holiday?

For most people, yes. Maps, messaging, social media and photo sharing usually fit within 1 GB per day. Heavy video users and remote workers should choose a higher daily limit or a fixed plan.

Where can I see the daily limit before buying?

On every TripoSIM destination page, unlimited plans show the daily full-speed amount and the speed after it, right under the price. For example: "1 GB/day at full speed, then 512 kbps".

The bottom line

"Unlimited" travel eSIMs are a great choice when your daily use is steady and moderate. Check the daily limit, not just the word "unlimited": 1 GB per day suits most travellers, while heavy users are better off with a Plus plan or a larger fixed plan.
