Thailand leads the global ranking at $0.29/GB via HelloRoam. That rate comes from a 50GB plan, where the volume discount drives the per-GB cost down sharply. The pattern repeats across Southeast Asia: high tourist demand brings more providers into the market, and competition keeps rates low. European destinations cluster in positions 2 through 20 because eSIM providers treat the entire EU as one coverage zone, spreading plan costs across a large potential buyer base.

Direct Answers

What is the difference between eSIM and SIM card?

An eSIM is a digital SIM built into your phone. A physical SIM is a removable plastic card. eSIM activates instantly via QR code without visiting a store. Physical SIM requires a trip to a carrier store or airport kiosk. Both connect to the same mobile networks. Most phones made after 2020 support eSIM.

What are the disadvantages of eSIM?

eSIM disadvantages include limited phone compatibility (pre-2020 devices lack support), inability to physically swap between phones, and some countries requiring IMEI registration within a set period. eSIM plans also cannot be resold or given to others. For travelers, these drawbacks are typically outweighed by instant activation and lower cost.

Can I use eSIM and physical SIM at the same time?

Most modern phones support dual SIM: one physical SIM slot plus one or more eSIM profiles. This lets you keep your home number active on the physical SIM while using an eSIM for local data abroad. iPhone 13+ and Samsung Galaxy S21+ support this configuration. iPhone 14 US models use two eSIM profiles with no physical SIM slot.

EU roaming rules mean a plan covering one EU country typically covers all 27 EU member states at no extra charge, which expands effective coverage significantly. Europe is one of the best-value regions for eSIM travelers. All Europe destinations →

HelloRoam holds the lowest average at $1.34/GB and wins on per-GB cost in 87% of destinations. Saily at $1.92/GB is the runner-up with 200-country coverage, the widest of any provider alongside Airalo and Nomad. Nomad at $3.20/GB ranks second on value, with strong rates in Switzerland, Norway, and parts of Central Europe. Airalo averages $2.48/GB but covers the most niche destinations and offers regional multi-country plans.

Holafly at $5.85/GB ranks lowest on per-GB value. The cost makes more sense for heavy streamers who consume 3GB+ daily, where the unlimited model avoids overage risk. Unlimited plans are measured by daily rate instead. Saily at $1.92/GB is a competitive mid-range option from the NordVPN team. For most popular destinations, comparing HelloRoam and Nomad covers the two cheapest options.

Strategy

How to get the lowest rate on a travel eSIM

1. Compare data tiers before buying

The cheapest per-GB rate for any country almost always comes from the largest data tier. In Japan, a 3GB HelloRoam plan costs $6.99 at $2.33/GB. The 50GB plan costs $30.60 at $0.61/GB, a 74% reduction in cost per gigabyte. If you are traveling for more than 3 days and expect moderate usage, buying a 10GB or 20GB plan instead of a 3GB plan can cut your effective data cost in half. Check the country page to see the full tier breakdown before committing.

2. Check unlimited plan daily rates for long trips

Unlimited plans drop in daily rate as trip length increases. In Germany, a 1-day unlimited plan costs $2.36/day. A 30-day plan drops to $2.02/day, a 14% saving. For destinations like Thailand, the 1-day unlimited rate is $3.35 versus a 7-day plan at $22.48 total ($3.21/day). If your trip is two weeks or longer and you stream or call daily, run the numbers against the largest fixed-data plan available. Both HelloRoam and Holafly cap unlimited high-speed data at 2GB per day, then throttle to 256kbps. Unlimited eSIM comparison →

3. Buy before you travel

Airport physical SIM kiosks charge 40 to 200% more than online eSIM prices. A kiosk SIM in Japan typically costs $22 to $35 for 3 to 10GB. An eSIM for Japan through HelloRoam starts at $6.99 for 3GB. The same pricing gap applies in Europe, the US, and Australia. Installing an eSIM before departure also means your phone works the moment you land, without queuing at a kiosk or store. Most eSIM profiles activate within a minute of scanning the QR code. eSIM vs physical SIM comparison →

Travel eSIM vs carrier roaming

Carrier roaming plans typically cost $5 to $15 per day with capped data. A prepaid travel eSIM for the same destination costs a fraction of that. The table below shows representative costs for a 7-day trip using 5GB of data.

Methodology

How we calculate cost-per-GB

Every price on PrepaidSIM uses the formula: plan price in USD divided by data in gigabytes. A 10GB plan at $7.00 = $0.70/GB. A 1GB plan at $3.50 = $3.50/GB. This normalization lets you compare plans of different sizes across all 5 providers on a single consistent metric.

Prices come from provider APIs and are converted to USD using ECB daily reference rates. Rankings update every Monday. Unlimited plans cannot be ranked by $/GB and instead show a daily rate (total price divided by validity in days). No provider pays for placement. Rankings are 100% price-driven.

FAQ

Cheapest travel eSIM — common questions

The cheapest travel eSIM in 2026 costs $0.29/GB from HelloRoam in Thailand. That rate comes from a 50GB plan priced at $14.38, making it the lowest cost-per-GB across all 213 destinations and 5 providers we track. For most popular travel destinations, HelloRoam also offers the lowest rate, with an average of $1.34/GB globally. Southeast Asian destinations like Thailand, Singapore, and Indonesia rank consistently among the cheapest.

Daily cost depends on how much data you use. A light traveler using 250MB per day on a $0.29/GB plan pays less than $0.10 per day. A moderate traveler using 750MB spends $0.20 to $1.50 per day. For comparison, carrier international day passes cost $5 to $15 per day with capped data. A prepaid travel eSIM covering a 7-day trip with 5GB of data typically costs $3 to $15 total, depending on the destination and provider. The cheapest eSIM data plans work out to under $0.50 per day for most travelers.

Yes, in almost every case. AT&T International Day Pass costs $10 per day. T-Mobile's international plan gives 2G speeds abroad at no extra cost, but requires a premium plan tier. Verizon's TravelPass runs $10 per day. A travel eSIM for the same destination typically costs 70 to 90% less. For a 7-day trip using 5GB, the difference between a $7 eSIM and $70 in roaming charges can be significant. The gap is largest in high-demand destinations where eSIM competition is strongest, like Japan, Germany, and Thailand.

HelloRoam has the lowest average price at $1.34/GB across 185 countries, winning on per-GB cost in 87% of destinations we track. Saily is the next cheapest at $1.92/GB on average. Airalo averages $2.48/GB but covers 200 countries, more than any other provider. Holafly averages $5.85/GB but offers unlimited data plans. The cheapest provider changes by destination, which is why comparing all 5 providers before buying matters.

Most travelers need 3 to 5GB for a week. Light users who stick to maps, messaging, and email use about 1.5 to 2GB per week. Moderate users who add social media and ride-hailing apps need 5 to 7GB. Heavy users who stream video or make video calls need 10GB or more. At Thailand rates of $0.29/GB, a 5GB plan costs under $2. Use the data usage calculator on PrepaidSIM to estimate your specific needs before buying.

Unlimited plans make sense for heavy users who stream video, join video calls daily, or share a hotspot with a laptop. HelloRoam's unlimited plans start at $1.33/day. For comparison, a fixed 10GB plan for a 14-day trip might cost $10 to $20 total. If you use less than 700MB per day, a fixed plan is cheaper. Unlimited plans are also a good fit when you do not want to track data usage. Both providers cap high-speed data at 2GB per day, then throttle to 256kbps.

eSIM plan prices from providers like HelloRoam, Airalo, and Holafly are set prices that do not fluctuate with travel seasons. Provider pricing is fixed until the provider updates it. However, airport physical SIM card prices can vary by season and location. The per-GB rate differences between destinations are stable year-round. PrepaidSIM verifies prices every week and updates rankings when providers change their plans.

Some providers offer regional plans that cover multiple countries under one price. Airalo and Saily both sell Europe and Asia regional eSIMs. These regional plans often cost 10 to 30% more per GB than single-country plans but remove the need to buy separate eSIMs per destination. For multi-country trips, compare the regional plan price against buying individual country plans for each stop. The cheapest-esim-by-region page on PrepaidSIM shows the cheapest option per region.
