Guide
Carrier roaming passes charge for the periods when you use your phone abroad. Travel eSIMs in our price table list a package price, a data allowance and a validity period. Compare those terms, not a daily roaming fee against an eSIM package price as if they cover the same thing.
The prices below were checked Oct 2026. Your choice depends on where you go, how much data you need and whether you want your carrier's talk and text service.
Checked Oct 2026 against official pages
AT&T International Day Pass costs $12/day on land in 210+ destinations. AT&T charges $6/day for each additional line on the same account used on the same calendar day. For land and air travel, AT&T caps charges at 10 daily fees per line, per bill period. That limit is tied to your bill period, not your trip.
AT&T lets you use your current plan, with its domestic terms and data allowance. A 24-hour charge period starts when you use data, send a text, or make or accept a call in an included destination.
Verizon TravelPass costs $12/day in other TravelPass countries and $6/day in Canada and Mexico. Verizon includes unlimited talk, text and data, with 5 GB of high-speed data per session, followed by unlimited data at 3G speeds. Verizon charges only on days you use your device.
For longer trips, Verizon lists its International Monthly Plan at $100/month per line, with 20 GB of high-speed data followed by unlimited data at 3G speeds. Verizon positions it for trips of 9 days or longer.
The T-Mobile provider pages available for this comparison do not state an international pass price, so we do not include a T-Mobile price comparison.
Match the eSIM's validity to your trip, then compare the data allowance. These package prices are not daily charges. They also should not be treated as equivalent to the talk, text and data included in a carrier pass.
For Japan, Saily lists 1 GB for 7 days at US$3.99 and 10 GB for 30 days at US$17.99. Yesim lists 20 GB for 30 days at US$29.76. Ubigi lists 25 GB for 30 days at US$32.00.
For a 7-day Japan trip, Airalo lists unlimited data at US$26.50, while Holafly lists unlimited data at US$27.50. For 30 days, Airalo lists US$69.00 and Holafly lists US$73.90 for their unlimited-data packages.
For Europe, Saily lists 1 GB for 7 days at US$4.99 and 10 GB for 30 days at US$35.99. Airalo lists unlimited data for 7 days at US$27.00; Holafly lists unlimited data for the same validity at US$27.50.
For Mexico, Saily lists 10 GB for 30 days at US$23.99, compared with Ubigi's 10 GB for 30 days at US$24.00. Airalo lists unlimited data for 7 days at US$23.50. Compare those package terms with Verizon's $6/day Mexico TravelPass rate, while checking whether your Verizon plan already includes Mexico service.
Roaming is worth considering if you want the talk and text service bundled with your carrier pass. AT&T International Day Pass uses your current plan. Verizon TravelPass includes unlimited talk and text alongside data. The trade-off is that using those services can start a paid session.
Check your existing coverage before buying anything for Canada or Mexico. Verizon says unlimited data, talk and text there are included with all Unlimited and other select plans.
If you travel with additional AT&T lines, its $6/day additional-line rate matters. For longer travel, compare Verizon's $100 International Monthly Plan with both TravelPass and an eSIM package, rather than assuming a daily pass is the right fit.
Consider a travel eSIM if you want to buy a defined data package for your destination. Saily's Japan 1 GB package costs US$3.99 and lasts 7 days. Its Japan 10 GB package costs US$17.99 and lasts 30 days. The lower-priced package gives you less data, so choose by allowance as well as price.
Longer validity does not mean more data. Yesim's Japan 1 GB package lasts 30 days and costs US$4.44, while Saily's Japan 1 GB package lasts 7 days and costs US$3.99.
Unlimited-data packages offer another comparison, but keep the label separate from speed. Verizon, for example, calls TravelPass data unlimited while specifying a high-speed allowance and slower service afterward.
If you plan to use an eSIM alongside carrier roaming, account for each service separately. An eSIM purchase does not remove AT&T's or Verizon's stated charging triggers. Calls and sent texts can start a carrier session, not only data use.
AT&T starts a 24-hour International Day Pass period when you use data, send a text, or make or accept a call. Verizon also starts a 24-hour TravelPass session when you use data, send a text, or make or answer a call. Verizon says using your device after that session ends starts a new session.
The provider pages we checked do not state whether your phone supports an eSIM alongside your carrier line or give the settings for that setup.
"From" is the lowest price we found on the provider's own destination pages (checked Oct 2026). Links go through our /go/ redirect; we may earn a commission.
AT&T charges when you use your device in an included destination. Data use, a sent text, or making or accepting a call starts a 24-hour period. For land and air usage, AT&T caps charges at 10 daily fees per line, per bill period.
No. Verizon includes 5 GB of high-speed data per TravelPass session, followed by unlimited data at 3G speeds for the rest of that session.
Verizon says unlimited data, talk and text in Mexico and Canada are included with all Unlimited and other select plans. Its listed TravelPass rate for Mexico and Canada is $6/day. Check which terms apply to your plan.
Saily lists 1 GB valid for 7 days at US$3.99. Airalo lists unlimited data valid for 7 days at US$26.50, and Holafly lists unlimited data valid for 7 days at US$27.50. Those packages have different data allowances.
