About this appAI proposal
Plainband sells travel eSIM data plans you can install from your phone's browser in three taps. No app to download and no account to create. Pick a country, see the plan, pay, then tap to install.
Every plan page states the data amount, the days, the real speed and what happens at the cap, before you pay. Each country page names the local network the plan uses and why it was chosen.
It is built for people visiting Vietnam, Mexico, Europe and the US who want data that works on landing, and who are tired of vague unlimited plans, forced sign-ups and padded prices.

- Why this name

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. Travelers buy once per trip and the product runs inside their phone settings, so it has no built-in way to reach other people. Growth comes from search, travel content and word of mouth.
- Do they become customers?
- Buyers are the customers, but each buys again only on a new trip. Test whether search for country plans converts at low cost and whether a share-with-travel-companions option adds orders.
- First customers
- Independent travelers visiting Vietnam or Mexico for one to four weeks, who currently compare eSIM options online before the trip.
- Where to reach them
- Travel forums and Reddit: Answer data-plan questions for Vietnam and Mexico trips with real speed and cap details and a link to the plan.
- Search content: Publish country pages on speeds, caps and networks that rank for 'eSIM Vietnam' and 'eSIM Mexico'.
- Hacker News and Show HN: Post the browser install flow and plan transparency to reach early tech-savvy travelers.
- First milestone
- Fifty paid plans for Vietnam and Mexico in 60 days at a positive margin after data costs.

RisksAI inference
- CommercialSelling at 2-3x below incumbents may leave no margin after wholesale data costs. Supplier prices for the strongest networks are not in the material and must be checked first.
- PlatformBrowser-based eSIM install depends on phone and OS support. Older or locked devices may need a manual QR code, which would weaken the three-tap promise.
- TechnicalOnly some wholesale suppliers offer the strongest local network in each country, and plan speeds and caps can change. Plan pages could become wrong.
- CommercialThe paying-customers-in-several-countries evidence is a public claim from a forum post and is unverified. Demand at this price is unproven.
- RegulatorySome countries require identity registration for SIMs or eSIMs. This could force sign-ups that break the no-account promise in those places.
