What a travel eSIM daily data limit really means: full-speed GB each day, then reduced speed
In short
Our daily-limit plans print the limit with the price. Our Japan plan is Unlimited — 3 GB/day at full speed, then reduced to 1 Mbps, at $23.99 for 7 days, data only.

This site is not affiliated with any carrier named on this page; we sell eSIMs. How we compare
You may not need an eSIM. If your carrier plan already includes data abroad, such as T-Mobile Experience Beyond or Google Fi Unlimited Premium, check its allowance first. A trip inside it needs no second plan.
One bill trap stays with our plan. A call or text on your Verizon line abroad can still start a $12 TravelPass day (checked on October 29, 2026, TravelPass FAQs).
What does a daily data limit mean on our plans?
A daily-limit plan gives a fixed amount of full-speed data for each day of its validity, then a lower speed. Our Europe plan is Unlimited — 5 GB/day at full speed, then reduced to 1 Mbps, at $26.99 for 7 days, data only.
We counted the daily-limit packages in our storefront data on October 30, 2026: all 754 state both numbers. Of these, 730 give 3 GB a day at full speed and 24 give 5 GB, each then 1 Mbps (our count).
The limit sits on each plan page beside the price, with no asterisk. We also checked 11 travel-eSIM sellers from a US IP on October 29, 2026. Every limit stated on their country pages was 3 to 5 GB a day at full speed, then about 1 Mbps.
On most of our plans the days start when the eSIM first connects at your destination — check the activation rule shown on your plan. Before you buy, check that your phone can take a travel eSIM: Is my phone unlocked? and Does my phone support eSIM?
Why do we print the limit next to the price?
On November 5, 2019, the Federal Trade Commission (FTC) announced that AT&T Mobility “will pay $60 million to settle litigation” (FTC release). The case was over FTC allegations that AT&T misled customers by “charging them for ‘unlimited’ data plans while reducing their data speeds.”
The same release, checked on October 29, 2026, says: “The disclosures need to be prominent, not buried in fine print or hidden behind hyperlinks.” That settlement binds AT&T; we hold our own plan pages to the same standard.
So our wording has three parts: the daily amount at full speed, then the reduced speed, both in the sentence that gives the price. There is no asterisk and no footnote behind a link. How we check plan data: our method.
How do carrier caps abroad compare?
Carrier plans abroad also give a high-speed allowance, then a lower speed. Verizon TravelPass on postpaid lines gives 5 GB at high speed per session, then 3G, for $12 a day ($6 in Mexico and Canada).
We compare public packages; check your own plan.
| High-speed allowance | After it | Price as printed |
|---|---|---|
| 5 GB per session | 3G | $12/day, $6/day in Mexico and Canada |
| 20GB | 3G | $100/mo per line, plus taxes and fees |
| your AT&T plan’s own data allowance | check your AT&T plan | $12/day; $6 for each additional line used the same day |
| up to 15GB | up to 256Kbps | included in the plan |
| up to 5GB | up to 256Kbps | included in the plan |
| 50 GB in 200+ destinations, counted in the monthly high-speed data | 256 kbps | included in the plan |
| 3 GB a day | 1 Mbps | $23.99 for 7 days, data only |
Verizon figures were checked on October 29, 2026 (TravelPass FAQs, monthly plan) and AT&T’s on October 29, 2026 (International Day Pass). T-Mobile’s were checked on October 29, 2026 (roaming plans) and Google Fi’s on October 29, 2026 (international rates).
Fi adds: “Data counts towards your monthly high-speed data usage.” The difference from our plan: a carrier allowance sits on your own number and plan, while ours is a data-only plan beside your line.

Should you pick a GB plan or a daily-limit plan?
Our Japan plan with 10 GB for 30 days costs $14.99, data only, with no daily cap. The 7-day daily-limit plan costs $23.99, data only: up to 21 GB at full speed, at most 3 GB a day (our arithmetic).
Our Europe plan for 7 days allows up to 35 GB the same way (our arithmetic). Both daily-limit plans also come in 3, 5, 10, 15 and 30 days, so match the days to your trip first.
Pick the GB plan when your trip needs less than its total or your days are uneven. A heavy day can then use what a quiet day left.
Pick the daily-limit plan when a week will take more than 10 GB and your days look alike. On it, a quiet day’s unused data does not carry over, and a heavy day slows once it passes the limit.

Frequently asked questions
Does a daily-limit eSIM cut off when the day’s data runs out?
No. It keeps working at the reduced speed it states until its days run out: 1 Mbps on our Japan and Europe plans. The reduced speed is printed on the plan page next to the price.
What happens after I use the daily full-speed data?
Your speed drops to the figure beside the price: 1 Mbps on our Japan plan with 3 GB a day. Each day of the plan has its own 3 GB at full speed. We have no data on the hour a new day starts or on what 1 Mbps supports, so we give neither.
Does the plan allow a hotspot?
The plan doesn’t state a hotspot rule — check the plan page. Our plan data has no hotspot rule for any of our plans.
