Cheapest eSIM Plans by Price per GB
A $3.99 plan is not automatically cheaper than a $17.99 one — it depends how much data you actually get. This page recalculates every capped plan we track into a single comparable unit, price per gigabyte, and ranks them from cheapest to most expensive.
How this list is ranked: Ranked by price ÷ included GB, cheapest first. Unlimited plans are excluded because they have no GB allowance to divide by — see the unlimited guide for those.

Frequently Asked Questions
Which travel eSIM has the lowest price per GB?▼
It varies by destination. Thailand and Turkey plans generally deliver the lowest cost per gigabyte, while Europe regional plans and UAE plans cost the most per GB because they bundle multi-country coverage. The table on this page is generated from our current verified pricing, so it reflects the latest figures we checked.
Is price per GB the best way to choose an eSIM?▼
It is the best way to compare value between capped data plans, but it is not the only factor. A very cheap per-GB plan with only 7 days of validity is a poor choice for a three-week trip, and a plan without hotspot support may not suit you if you tether a laptop. Use price per GB to shortlist, then check validity and tethering.
Why do some plans show a lower total price but a higher price per GB?▼
Small starter plans usually carry a higher unit price. A 1 GB plan at $3.99 costs $3.99 per GB, while a 10 GB plan at $17.99 costs $1.80 per GB — less than half as much per gigabyte, despite the bigger sticker price.
Other Comparison Guides
Travel eSIMs That Allow Hotspot and Tethering
If you work while travelling, tethering matters more than the headline data allowance. Some providers allow it without limits, some cap it to a daily amount, and some never state a policy at all. This page lists only the plans that explicitly document unrestricted hotspot use.
Unlimited Data eSIMs and Their Real Fair-Use Limits
'Unlimited' rarely means unlimited at full speed. Most providers give you a generous daily allowance and then slow the connection sharply for the rest of the day. This page compares unlimited plans by their real cost per day of validity and shows the fair-use cap each one applies.
