I Built a Habit of Checking One Site Before Every International Trip — It Quietly Saves Me Money Every Time
Posted to Indie Hackers · April 2026
This is not a post about a big insight or a dramatic lesson learned.
It is about a small habit that compounded quietly over the past year into a few hundred dollars saved and zero roaming bills — which for someone who travels internationally six or seven times a year for work and client meetings, actually adds up to something worth sharing.
The habit: before every international trip, I spend five minutes on esim.coupons to find the best travel eSIM plan for my destination, apply a discount code, and have everything installed on my phone before I leave home.
That is genuinely the whole thing. But let me give you the context that makes it useful.
The version of me that didn't do this
For the first two years of running my business independently, I had a completely passive relationship with travel data costs.
I would land at an airport, turn off airplane mode, get hit with a roaming notification from my carrier, and either accept the $10-per-day add-on or spend twenty minutes in arrivals hunting for a SIM card kiosk. Both options were expensive, stressful, or both.
The mental model I had was: travel data is expensive. That's just how it is.
That mental model was wrong. And the reason it persisted was not because good alternatives didn't exist — they did, and have for a while. It's because nobody had given me a reason to spend twenty minutes researching a market I'd assumed was a commodity.
A founder friend eventually gave me that reason. He mentioned that cheap international eSIM plans were now widely available through comparison platforms, that the price differences between providers were surprisingly large, and that the whole thing could be sorted in the time it takes to make a coffee.
What I actually found when I looked
The travel eSIM market in 2026 has five serious providers covering most of the world: Airalo, Saily, eSIMo, aloSIM, and Airhub. Between them they cover 150+ countries and list thousands of individual plans.
The problem — which is also the opportunity — is that prices for the same destination vary wildly between providers. Not slightly. Significantly. For Japan, for example, a 5GB plan ranges from about $12.90 to $23.28 depending on the provider. For the same connectivity. In the same country.
esim.coupons is a free platform that pulls all five providers onto one page for any country you search. You can filter by trip duration and data amount, and sort by price or by value per gigabyte.
That last option — sorting by price per GB — is the thing that made the comparison immediately useful for me. Rather than comparing $18 against $12.90 as raw numbers, I could see $1.80/GB against $2.58/GB. Suddenly the decision was obvious in a way it hadn't been before.
The site also shows the connection speed for each plan's throttled tier — what you actually get after the high-speed data runs out. I hadn't thought about this before using the site, but it turned out to matter. A $0.90/GB plan throttled to 900kbps is borderline usable. A $2.58/GB plan running at 2,580kbps handles video calls and navigation without any stress. Seeing both numbers on the same row changed how I evaluated plans entirely.
The coupon codes are not a gimmick
The site has a dedicated eSIM coupons page that I almost skipped the first time. I assumed it would be the usual graveyard of expired promo codes that most coupon sites are.
It isn't. The codes are listed with their discount amounts and expiry dates, marked as active, and they work at checkout. AIRALOESIM10 gives 10% off Airalo plans. ESIMCP gives 10% off eSIMo and 15% off a first aloSIM purchase. I have applied one before almost every purchase over the past year and they have worked consistently.
On a $18 Airalo plan, 10% off is $1.80. Not life-changing. But across eight trips it is $14.40 in savings that required zero effort beyond opening one extra tab. The compounding logic of small, repeatable optimisations applies here just as it does in business.
The practical result
I now do this the evening before every international trip. Search the destination, filter to my trip length, sort by value per GB, check the speed column, open the coupons page in a new tab, apply the code, buy, scan the QR code, install on my phone.
The eSIM is active before I board. I land in the destination city already connected. Google Maps works before I reach passport control. No airport SIM card queues. No roaming notifications. No surprise line items in next month's expenses.
For Thailand last October I paid $9.50 for an Airhub 3GB plan over 15 days. For Germany in January I paid around $11 for a solid Airalo plan covering my whole stay. For Japan in March I paid $16.20 after the coupon code for 10GB over 30 days.
Compare that to the $95–$120 per trip I was spending before. The maths is not complicated.
The reason I'm writing this here specifically
The Indie Hackers community has a lot of people who travel internationally with some regularity — for client work, conferences, co-working stints, or just because the whole point of running your own thing is the flexibility to move around.
I think a lot of us apply a founder mindset to our software costs, our tooling, our subscriptions — and then completely switch off when it comes to travel overhead. Roaming fees become one of those things we silently accept rather than spend twenty minutes optimising once.
The infrastructure to do this better has been in place for a while. Instant eSIM activation, transparent international data plan comparison, working discount codes — all of it exists and all of it is free to access. The only cost is five minutes before you leave.
If you are still paying roaming add-ons out of habit, try the comparison before your next flight. You will almost certainly find a better deal and arrive connected regardless.
Happy to answer questions if anyone has them — particularly around specific destinations or devices.
