One price. Every country. $5.00 a gigabyte.
We spend our days comparing eSIM plans, and the most common thing people tell us is that they do not want to do this. They do not want to check a table before every trip, work out which plan fits, or discover that the volume discount needed 20 GB they were never going to use.
So we are considering our own eSIM with exactly one number attached to it. $5.00 per GB, in every country we cover. Credit that never expires. Nothing else to decide.
It does not exist yet. Whether we build it depends on how many people tell us they would use it, which is what this page is for.
Flexible data-only usage examples for an existing eligible subscriber: one line, one billing cycle, no other data use, and no optional full-speed purchase. These are not standalone travel packages; 30 days is an illustration, not purchased validity. Ordinary data costs $10 per GB up to $60 after 6GB. The required $20/month service base, taxes, fees and other charges are separate ($80 combined base and ordinary data at the cap, before extras). Group Bill Protection thresholds differ. Domestic and overseas data share the cycle: prior usage can reduce the incremental data charge; crossing billing cycles changes the total.
After 15GB per member in a billing cycle, speeds slow to 256kbps. Restoring full speed is optional and costs an additional $10 per GB for the rest of that cycle; it is not included in the $60 ordinary-data cap.
Requires US residency, initial US activation, primarily US use and an active voice subscription in good standing. Activate and use service, including new SIMs and devices, in the US for at least one day before travel. Extended roaming can lead to international-data suspension; no 90-day allowance is guaranteed. Check destination coverage with Fi; the existing coverage list was not reverified by this shared pricing review.

What if it was just $5.00 a GB, everywhere?
We are considering a BetterSIM eSIM at one flat rate worldwide. No tiers, no packs, no per-country price shopping, no volume discounts you never reach. The same price in Japan as in Fiji or Kenya.
Straight answer: this would not be the cheapest option. The plans listed on this page are often less per GB, especially in Europe and Asia. It would be the simplest. Savings against Google Fi depend on usage, Bill Protection and speed needs.
Where this is a bad deal
We compare eSIMs for a living, so we are not going to pretend a flat rate wins everywhere. It does not. Here is the cheapest 3 GB plan we currently track in six countries, against our $15.00.
| Destination | Cheapest 3 GB we track | Flat rate | Verdict |
|---|---|---|---|
| Japan | $4.99 (GoMoWorld) 3 GB to use within 7 days, Japan only. Price from GoMoWorld's site on Oct 26; tax may be added at checkout. | $15.00 | They are cheaper by $10.01 |
| France | $4.50 (Virgin Connect) 3 GB to use within 30 days, France only. Runs on Bouygues, Free Mobile and 2 more, up to 5G. Price from Virgin Connect's site on Oct 26; tax may be added at checkout. | $15.00 | They are cheaper by $10.50 |
| Thailand | $5.49 (GigSky) 3 GB to use within 15 days, Thailand only. Price from GigSky's site on Oct 26; tax may be added at checkout. | $15.00 | They are cheaper by $9.51 |
| Cuba | $49.00 (Nomad) 3 GB to use within 30 days, Cuba only. Price from Nomad's site on Oct 26; tax may be added at checkout. | $15.00 | We are cheaper |
| Bhutan | $35.99 (GoMoWorld) 3 GB to use within 30 days, Bhutan only. Price from GoMoWorld's site on Oct 26; tax may be added at checkout. | $15.00 | We are cheaper |
| French Polynesia | $24.99 (GoMoWorld) 3 GB to use within 30 days, French Polynesia only. Price from GoMoWorld's site on Oct 26; tax may be added at checkout. | $15.00 | We are cheaper |
The pattern is consistent: in Europe and mainstream Asia, per-country plans beat a flat rate, often by a lot. Off the beaten track, a flat rate wins and sometimes wins enormously. What it always does is stay the same, which is the whole point. You can see every price we track on our destination pages and decide for yourself.
How we check pricesWhere every price on this page comes from · last check Oct 26
Each week we read every plan’s advertised price from the provider’s own site or its partner price feed and record what the page said, when we read it and where. We never type prices in by hand. The final total can differ at checkout (tax, promotions, your account), so the provider’s checkout is always the price that counts. Below is the full record for each plan on this page.

What this would and would not be
- Not the cheapest eSIM you can buy
- If you are happy to compare plans for each trip, you will beat this price in most popular destinations. Our site will keep helping you do that, whether or not we ever launch this.
- Compare the cost for your usage
- Google Fi Flexible charges $10 per GB up to a $60 ordinary-data cap for one line in a billing cycle, plus required service and extras. Savings depend on usage, billing cycles and speed needs; this would not always halve your bill.
- Credit that never expires
- Data you paid for and did not use would stay yours for the next trip. No 30-day windows, no re-buying because a plan lapsed while you were home. Charging you for data you never used is exactly the thing this is meant to get rid of.
- No card, no account, today
- The launch list is an email address and one question. We will write once, when we decide either way, and that includes writing to say we decided not to build it.
