👍 What we like

✓Validity starts on first network connection, not at purchase — you can install early without burning days

✓Top up the same installed eSIM when data or validity runs out, so no re-scanning a new QR profile

✓Unlimited-data options in the lineup, including unlimited plans for Europe

✓Broad reach — 2104 live plans across 213 countries, with local, regional, and global options from $2.99

✓Written 30-day refund window with full refunds for never-installed eSIMs

✓Dedicated iOS and Android apps to purchase, install, and manage several eSIMs in one place

👎 Worth noting

–No pay-as-you-go or no-expiry options — every plan runs on a fixed validity period

–Plans bought with a discount code become non-refundable once the eSIM is installed or activated

–The DTAC Thailand 50GB plan and Unlimited plans carry separate refund terms, so the standard 30-day policy doesn't fully apply to them

–Refund processing time and payout method aren't specified in the published policy

About CloudOn eSIM

You can buy either on the cloudon.app website or in the CloudOn app (App Store / Google Play): pick a local single-country, regional, or global destination, then a data amount and validity. After payment you scan the eSIM QR code or install directly from the CloudOn app, which also stores and manages your eSIMs. Installation needs an internet connection, so set it up on Wi-Fi before you fly; the plan's validity only starts when the eSIM first connects to a network at your destination, and CloudOn quotes under 60 seconds to get online on arrival. When data or validity runs out you can top up the same installed eSIM instead of installing a new profile.

CloudOn eSIM — quick answers

What is the cheapest CloudOn eSIM plan?

On esimadvice.com, live CloudOn plans start at $2.99, drawn from 2104 plans across 213 countries. The lineup spans local single-country, regional, and global options, including unlimited-data plans, so it's worth comparing a small fixed-data plan against an unlimited one for your destination before checking out.

Is there a CloudOn discount code that actually works?

Yes — our exclusive code ESIMDUDE5 gives 5% off, and it's already auto-applied to the CloudOn prices you see on esimadvice.com. One honest caveat from CloudOn's own refund policy: plans purchased with a discount code become non-refundable once the eSIM is installed or activated, so double-check your device compatibility before installing.

When does a CloudOn eSIM's validity period actually start?

Validity starts when the eSIM first connects to a network — not when you buy or install it. That means you can install the eSIM QR code on home Wi-Fi days before departure (or install directly from the CloudOn app), then enable the line on arrival; CloudOn says you'll be online in under 60 seconds.

What is CloudOn's refund window and what qualifies?

You have 30 days from purchase to request a refund via website or in-app chat. Full refunds only apply if the eSIM was never installed or activated; after activation, partial refunds for unused data are limited to cases of minimal usage plus a verified network or technical failure. The Thailand DTAC 50GB/10-day plan and Unlimited plans follow separate terms.

Can I top up a CloudOn eSIM instead of buying a new one?

Yes. When your data or validity runs out, CloudOn lets you top up the same installed eSIM to keep going, so you don't need to delete the profile and scan a new QR code mid-trip. Note there are no no-expiry pay-as-you-go options, so each top-up still comes with its own fixed validity period.
