At the time of writing, Yoho Mobile offers a free travel eSIM trial, a small data plan you claim in its app, so try it first, then buy through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. Roamless does not list a free trial, but you can start with a small pay-as-you-go top-up that never expires. Jetpac advertises a money-back guarantee. Test first, then buy your trip plan through ShopBack US.
ShopBack US is a free app and website that returns part of what you spend at partner stores as cash you can withdraw. Before you buy an eSIM, open the store's page on ShopBack, tap through and pay as normal. Join ShopBack US for free, then open Klook, Yoho Mobile or Roamless on ShopBack.
The verdict
Use a free trial to test your phone, not to cover your trip. If you have never used an eSIM, Yoho Mobile's in-app trial is the easiest way to confirm your phone installs and connects to one. For the trip itself, pick the eSIM whose network and plan size fit where you are going: a fixed-day plan for a one-country trip such as Japan, or pay-as-you-go credit if you travel often and use little data. Then go through ShopBack before you buy.
Which travel eSIMs offer a free trial before you buy?
Yoho Mobile offers a free trial data plan at the time of writing; Roamless and Jetpac offer other ways to try before you commit. Here is what each company says on its own site:
| eSIM | Free trial? | How you can try it | Coverage the company states |
|---|---|---|---|
| Yoho Mobile | Yes, a free trial data plan | Claim in the Yoho Mobile app only | 200+ countries and regions |
| Roamless | Not listed | Start with pay-as-you-go credit that never expires | 200+ destinations |
| Jetpac | Not listed | Money-back guarantee under its refund policy | 200+ destinations |
| Klook | Not listed | Short plans from 1 day on some destinations, such as Japan | 50+ countries for eSIM, SIM and pocket WiFi |
Yoho Mobile's free trial is on its Free eSIM page, which says free data is only available in the Yoho Mobile app, on the App Store and Google Play. You install the eSIM, claim the trial data and check that your phone connects. Yoho Mobile also lets you build your own plan by choosing countries, data and days, and one eSIM can cover several countries on a multi-country trip.
Roamless works differently. According to Roamless, you install one global eSIM once and use it in 200+ destinations, paying per MB from a credit balance that never expires. That makes a small first top-up a low-risk way to test it, and any credit you do not use carries over to your next trip.
Jetpac does not list a free trial, but its site advertises a money-back guarantee, with details in its refund policy. It also says WhatsApp, Google Maps, Uber and Grab keep working even when your data plan runs out.
Free eSIM trials in 2026: what to check before you claim one
A free trial only proves the eSIM works on your phone; it does not prove the plan is right for your trip. Four checks matter more than the trial itself:
- Your phone supports eSIM and is unlocked. Most recent iPhones and many Android phones support eSIM, but a carrier-locked phone may not accept another provider's eSIM. Our guide to using an eSIM on an iPhone abroad walks through the settings.
- The network at your destination. Check which local network the plan uses, because coverage differs by network, especially outside cities.
- When the plan starts. Roamless says its data plans start counting from your first use, so you can buy before you travel without losing days. Check each provider's rule.
- Hotspot use. If you will share data with a laptop, check that tethering is allowed. Roamless lists unlimited hotspot use on its Japan and Mexico pages.
What is the best eSIM for a trip to Japan?
The best eSIM for Japan is one that runs on a major Japanese network and has enough data for the days you are there. Japan's main networks include NTT DOCOMO, KDDI and SoftBank, and the eSIMs on ShopBack US say they use these:
| eSIM | Japan network the company lists | Plan style |
|---|---|---|
| Roamless | KDDI and SoftBank, with 5G on SoftBank | Pay-as-you-go credit, 30-day data plans or unlimited plans |
| Klook | SoftBank 5G and DOCOMO 4G LTE | Data-only plans, 1 to 30 days |
| Yoho Mobile | Shown on the Japan plan page | Build your own plan by data and days |
Roamless's unlimited plans give 3GB of full-speed data a day under its fair usage limit, then keep you connected at 1 Mbps until the allowance resets 24 hours later, according to Roamless. That suits heavy map and translation use in Japan. Klook suits travelers who are already booking rail passes, attraction tickets or tours on Klook and want the eSIM in the same app.
If you are still planning dates, our guide to the best time to visit Japan for cheaper flights and hotels covers the season side.
What is the best eSIM for traveling in Mexico?
For Mexico, start by checking whether your US phone plan already covers it; if not, a travel eSIM is usually the simplest option. According to Roamless, its eSIM uses Movistar in Mexico and allows unlimited hotspot use. Yoho Mobile and Jetpac also sell plans that cover Mexico, and each lists its own data and day options.
How to choose for Mexico:
- Beach resort week: a fixed plan with modest data is usually enough if your hotel has Wi-Fi.
- Road trip or Mexico City: pick a larger plan or unlimited data, since maps and ride-hailing use data all day.
- Several trips a year: Roamless pay-as-you-go credit that never expires can work out simpler than buying a new plan each time.
Yoho Mobile vs Roamless: price comparison for 2026
Neither is cheaper on every trip, because they price data in different ways. Yoho Mobile sells plans you build by country, data and days. Roamless sells pay-as-you-go data per MB, fixed 30-day plans such as 5GB, 10GB and 20GB, and unlimited plans by the day.
| If your trip is... | Usually the better fit | Why |
|---|---|---|
| One country, fixed dates, steady data use | A fixed plan from Yoho Mobile, Roamless or Klook | You pay a set price for a known amount |
| Several countries in one trip | Yoho Mobile multi-country plan or Roamless global eSIM | One eSIM across borders |
| Short trips several times a year | Roamless pay-as-you-go | Credit never expires, so nothing is wasted |
| Heavy daily use | An unlimited plan | No need to track data |
Compare the total for the same destination, data and days on each site at the moment you buy, since plan prices change often. Other eSIM stores on ShopBack US include Jetpac, Airalo and Saily.
Yoho Mobile, Roamless and Jetpac: what each does well
- Yoho Mobile: an in-app free trial, build-your-own plans and multi-country coverage.
- Roamless: one global eSIM you install once, credit that never expires, and free calls and messages between Roamless users.
- Jetpac: a reusable eSIM you top up for each trip, essential apps that keep working when data runs out, and SmartDelay, which gives airport lounge access if a flight you registered has a qualifying delay.
How ShopBack lowers what you pay for an eSIM
ShopBack works like an automatic cash discount on your online order. The routine for an eSIM is the same as for the rest of your trip:
- Sign up free at ShopBack US or in the app.
- Test your phone with a free trial if you need to, and pick the plan for your trip.
- Before you pay, open the store's page on ShopBack, such as Klook, Yoho Mobile or Roamless, and tap through.
- Buy the plan.
Your effective price is what you pay minus the cash that comes back; the live rate is on the store's ShopBack page.
Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.
The same habit works for the bigger parts of the trip. Before you book a hotel on Booking.com or Agoda, go through ShopBack first: open Booking.com or Agoda on ShopBack US, then book as normal.
Using promo codes and ShopBack on the same eSIM order
eSIM stores often run their own promo codes and referral credits. No code is needed for Cashback: go through ShopBack before you pay.

How do I get the Yoho Mobile free eSIM trial?
According to Yoho Mobile, free trial data is only available in the Yoho Mobile app, so download the app from the App Store or Google Play and claim it there. Your phone has to support eSIM and be unlocked. The trial is a small data plan meant for testing, so buy a full plan for the trip itself.
What is the best eSIM for a trip to Japan?
The best Japan eSIM is one that runs on a major Japanese network and matches how much data you will use. According to Roamless, its eSIM uses KDDI and SoftBank in Japan, with 5G on SoftBank.

Usually not. A free trial is designed to let you test installation and coverage, not to carry a full trip. Use it to confirm your phone works with eSIM, then buy a plan sized to your trip.
Is Yoho Mobile or Roamless cheaper?
It depends on the trip. Yoho Mobile lets you build a plan by choosing countries, data and days, which suits a fixed itinerary. Roamless suits light or irregular use, because its pay-as-you-go credit never expires, and it also sells 30-day data plans and unlimited plans. Compare the total for the same destination, data and days.

Install it at home on Wi-Fi a few days before you fly, then switch it on when you land. Jetpac says you can download its eSIM first and activate it just before you travel, and Roamless says its plans start counting from your first use.
How does ShopBack lower the price of an eSIM?
ShopBack works like an automatic cash discount on your online order. Open the eSIM store's page on ShopBack US, tap through and buy, and part of what you spend comes back as cash. The live rate are on each store's ShopBack page.
Is ShopBack Cashback the same as airline miles?
