About eSIM Advice
I built eSIM Advice so travelers stop overpaying for data.
Hi, I am Ali. I started an international travel business in 2016 — flights, hotels, and itinerary platforms built on travel APIs — and I have visited 29+ countries since. Every trip, the same thing: search for an eSIM and drown in ads, buy from whoever shouted loudest, forget the good name you saw yesterday. So instead of launching yet another eSIM store, I built an independent travel eSIM comparison directory that puts the genuinely cheapest, most useful plan first.
Why I built it
Search “Thailand eSIM” on Google and you get a wall of ads. You click one, buy, and never find that site again. As of August 2026 we have catalogued 1,500+ travel eSIM brands — and most are white-label storefronts reselling the same data at a markup.
The travel data market is huge, fast-growing, and badly organized — easy to spin up one more eSIM store, nearly impossible for a traveler to find the genuinely cheapest, most reliable plan. eSIM Advice does the heavy work instead: live data synchronization and API feeds straight from the providers, every plan normalized and re-priced daily, verified coupon codes already applied. You just filter and choose. The choice
I could have sold eSIMs. I chose not to.
With my background, launching a store would have been the easy route: integrate a few provider APIs, plug in a payment gateway, ride the demand. Honestly, it would probably have made more money, faster. But the problem — travelers overpaying because they cannot compare — does not get solved by one more shop.
Why a reseller can never be the cheapest
If I sold eSIMs myself, I would also be a reseller. I would buy data through provider APIs at a set price and add my margin on top. There is no way for a reseller to be the genuinely cheapest option — and in the end, the traveler loses. Every “deal” quietly costs you more.
So I went the other way. eSIM Advice is a comparison and directory website, not a store. We send you straight to the real provider’s checkout with the best price and coupon already applied, and we make money only through transparent affiliate links — never by marking your data up.
An honest truth
An eSIM is not always the cheapest option — and anyone who tells you otherwise is selling something.
In Yerevan, Armenia, I once bought an airport SIM for about $9 for a full week with truly unlimited data and 100 minutes of calls. No eSIM could match it. Sometimes a local or airport plan wins on raw price. But most of the time an eSIM is both cheap and far more convenient: no queue at the SIM counter, no handing over your passport, no wasted time. You scan a QR code and you are online in one tap. So honestly, it is as much about convenience as cost — and we will always tell you which one actually wins for your destination. Use the data calculator to size it up first. How it works
We research 1,500+ providers. You see only the ones worth trusting.
Here is the trap comparison solves: you buy a Thailand eSIM from a big brand, and next month their email sells you the next trip for $10 — while the same plan sits at $5 elsewhere. On eSIM Advice you see it side by side, along with the details ads never show: the actual network used, IP breakout country, throttling and fair-use rules, hotspot support, and real price per GB. We shuffle, filter, and verify — keeping the top companies and cutting the low-quality white-label resellers — so you compare with confidence.
What eSIM Advice does
- Compare real plans by price per GB, data size, validity, hotspot support, 5G, and country coverage.
- Show coupon-aware prices only when the discount is active, useful, and applies at checkout.
- Filter out white-label resellers and keep only providers worth a traveler’s trust.
- Tell the truth when an eSIM is not the cheapest option for a destination.
- Keep refresh dates, methodology, and affiliate disclosure visible where you decide.
What eSIM Advice will not do
- Do not sell rankings or move a provider up because the commission is better.
- Do not invent plans, reviews, ratings, savings, or provider claims.
- Do not resell eSIMs ourselves, because a reseller can never be the genuinely cheapest option.
- Do not use fake urgency, countdown timers, or artificial scarcity.
- Do not hide uncertainty when a provider still needs more checking.

Ali
I started an international travel business in 2016 — flight bookings, hotels, and itinerary platforms built on travel APIs — and I have been a digital nomad for most of the decade since: four years in Thailand, two in Vietnam, three in India, a year and a half in Dubai, nine months in Prague. These days I am based in Batumi, Georgia. All that roaming is the qualification — I have queued at the airport SIM counters and overpaid on roaming so you do not have to.
eSIM Advice is built entirely by me: the data model, the comparison engine, the provider verification, and the words on every page. That hands-on approach is the point — provider trust, coupon checks, and travel guidance need human judgment, not just automation. If we get something wrong, I fix it. If a provider is not ready, we hold the page back. Questions, corrections, or press? Get in touch — I read them.
Behind the build
What it actually took to launch eSIM Advice.
I launched in January 2026, but optimizing and hardening it took five more months. This is the honest, unglamorous version of how it came together.
After years in travel affiliate marketing, eSIM Advice went live as an independent comparison directory.
Testing, bug fixing, and audits from outside companies before and after launch to make the system trustworthy.
Including ~$5,000 of auditing and bug fixing, AI-assisted engineering (Claude Code Max at $200/month), data, and tooling.
Travel, logistics, and eSIM pricing research, plus partnership and API agreements with real providers.
Negotiated discount codes and data agreements so travelers can save more than they would buying direct.
Each provider catalogue is re-synced from its feed on a fixed weekday, so every price on the site is at most a week old — usually a day.
How we make money
Affiliate commissions, clearly disclosed.
eSIM Advice is free to use. When you choose a deal, we may send you through a tracked affiliate link, and the provider may pay us a commission if you buy. That keeps the lights on — but it never buys a better ranking.
The honest model
Usefulness comes before commission, every time. The comparison still has to serve you first: a fair price, enough data, the right validity, clear country coverage, honest coupon context, and a provider you can trust. Read the full affiliate disclosure and our testing methodology for the details.
We also negotiate exclusive coupon codes with providers so you save more than buying direct — and the discounted price is shown up front, with the original price struck through.
About eSIM Advice FAQ
Things people ask before they trust us.
Who built eSIM Advice?
eSIM Advice was designed and built end to end by Ali, its founder. He started an international travel business in 2016 — flight booking, hotels, and itinerary platforms built on travel APIs — has visited 29+ countries, and has lived as a digital nomad across Thailand, Vietnam, India, Dubai, Prague, and now Batumi, Georgia.
Do you sell eSIMs directly?
No. eSIM Advice is an independent comparison and directory website, not a reseller. We deliberately chose not to launch an eSIM store, because a reseller buys data through provider APIs and can never be the genuinely cheapest option for travelers.
Is an eSIM always the cheapest way to get data abroad?
No, and we will not pretend otherwise. In some places an airport or local SIM with truly unlimited data can beat every eSIM. In Yerevan, Armenia, I once bought an airport plan for about $9 for a week with truly unlimited data and 100 minutes of calls that no eSIM could match. eSIMs usually win on price, and almost always win on convenience.
How do you decide which providers to list?
As of August 2026 we have catalogued more than 1,500 travel eSIM brands and white-label resellers — the real number could be higher. We filter that down to verified, trustworthy companies: we check website legitimacy, checkout clarity, plan details, coupon behavior, refund and support language, and buy and test providers when we mark them as verified.
Is the AI on eSIM Advice real?
Yes. Roami, our AI advisor, answers over the live plan catalogue — real plans, real prices, real coupon codes — so every recommendation is something you can actually buy, usually in under a minute. Ask a generic chatbot the same question and you get generic answers, because it has no live data feed. A human still makes the final call on provider trust and editorial guidance.
What is esimcruise.deals?
Our dedicated cruise initiative. Connectivity at sea is its own problem — Starlink-backed ship WiFi, port-day eSIMs, plans that roam onto maritime networks and plans that never will. esimcruise.deals and our cruise eSIM guide cover which eSIMs actually work on cruises and how to buy them.
How does eSIM Advice make money?
We may earn an affiliate commission when you buy through a tracked provider link. That keeps the site free to use, but it never lets a provider buy a better ranking. Usefulness and honest price comparison come first. See our affiliate disclosure for details.
