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/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/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.

Google Fi is a US phone plan that roams. A travel eSIM is a prepaid data pack. Compare them as those two things, not as two eSIM stores.
Full write-up of the carrier itself: Google Fi provider review. Side-by-sides with the data-only brands we track: Fi vs Nomad, Fi vs Saily, Fi vs GoMoWorld, Fi vs GigSky.
The short answer, by traveler type
Eight common situations. Fi is a yes only when the thing you need is a US phone plan that also works abroad.
Stored travel rates and Fi Bill Protection
Fi has a $60 ordinary-data cap for one line in one billing cycle, plus base and extras. Travel rows below are stored examples, not freshly verified prices or equivalent speed guarantees.
Those multiples are why a data-heavy week in Thailand or India should not run on Fi data. The same table is why a light Flexible month can still be rational if what you are buying is the US plan, not the gigabytes. For a trip-shaped total, use the cost calculator.
Flexible pricing and older Fi plan examples
Only the one-line Flexible pricing was checked October 10, 2026. Other tier prices and allowances below are older stored examples, not current quotes. Roaming depends on the plan and destination. Check Google Fi before choosing a subscription.
Flexible is the only tier that bills $10/GB. The unlimited tiers trade a higher monthly base for a high-speed bucket. None of these is a one-trip SKU. Details and the residency rule live on the Fi provider page.
Scenario math: monthly plan vs one trip
Four ways the same $10/GB rate shows up in real trips. We only use prices from the table above and the Fi menu. We do not invent a 10 GB Europe travel-eSIM SKU.
A. Europe, about 10 GB, one trip
If you do not already live on Fi, do not open a US phone plan for a single Europe trip. One-line Flexible costs $80 for base plus 10GB ordinary data in one billing cycle, before taxes, fees and extras. The UK/France entry sample we list is $3.99 for 4 GB / 7 days — not a 10 GB equivalent, which is why the cost calculator and plan finder exist.
B. Keep the number, buy data (dual-SIM)
This is the dual-SIM case: Fi remains the default voice and SMS line so banks, 2FA, and callers still hit your US number. Cellular data moves to the travel eSIM. The incremental cost of the trip's data is the travel plan, not $10/GB. Same pattern on Canada, India, Japan, or Thailand.
C. Light month on Flexible
Light travelers who want one US bill and only sip data can stay on Flexible and skip a travel eSIM. The moment the trip looks like Canada 50 GB or India 55 GB, compare Fi's capped charge and reduced speeds with the travel option in scenario B.
D. Heavy Canada or India
Head-to-heads if you want the rest of the product comparison, not just the rate: Google Fi vs Nomad, Google Fi vs GoMoWorld, Google Fi vs Saily.
Compare stored travel offers for your trip. Fi billing depends on your subscription, cycle usage and speed choices.
Fi-only, Fi plus a travel eSIM, or skip Fi
Three setups. Pick one on purpose so the phone does not pick roaming for you.
- You are a US resident who needs voice and SMS on a real US number
- Trips are frequent and short, and buying a pack every time is the hassle
- One-line Flexible suits your usage: $20 base plus capped ordinary data, taxes, fees and extras
- You already pay for Unlimited Plus or Premium and the trip fits the high-speed bucket
- You are not a US resident
- Your primary use would be outside the US
- The trip is a cruise or at-sea itinerary (GigSky, not Fi)
- You only need one-trip data and do not want a US phone plan
The dual-SIM middle: Fi plus a travel eSIM
Use this when Fi is already your US plan (you want the number) and the trip is data-heavy enough that $10/GB hurts. Fi stays on for voice and SMS. A travel eSIM carries data. That is the same pattern as any home line plus a travel pack — Fi is just the home line. International hotspot on iPhone is supported (Personal Hotspot APN h2g2-t); the reason for a travel eSIM here is price, not a hotspot gap.
- Leave Fi as the default voice and SMS line
Outbound calls, iMessage / FaceTime, and bank texts stay on the US number. Do not move default voice onto the travel eSIM.
- Set the travel eSIM as the cellular data line
All maps, apps, and hotspot traffic should ride the travel plan. Install it at home on Wi-Fi; the setup guide is the order that works.
- Turn Data Roaming OFF on Fi
If Fi roaming stays on, a weak travel-eSIM signal can still pull $10/GB. This is the expensive toggle.
- Turn Data Roaming ON for the travel eSIM
Travel eSIMs route as roaming on a local carrier. The line needs roaming enabled even though you prepaid.
- Turn Allow Cellular Data Switching OFF
On iPhone this is the silent-roaming trap. With it on, iOS falls back to Fi when the travel line dips. Off means you stay on the travel eSIM. Walkthrough: eSIM on iPhone.

How we built this page
What is in this guide, what is not, and how we get paid.
Travel-eSIM prices here are stored examples, not refreshed by this Flexible pricing review: Nomad 50 GB / 30 days in Canada at $49; GoMoWorld 55 GB / 30 days in India and Japan at $29.99; Nomad 50 GB / 10 days in Thailand at $9; GoMoWorld 4 GB / 7 days in the UK and France at $3.99 as entry samples; Nomad 1 GB / 7 days in Mexico and Australia at $4 as entry samples. Rate ratios alone do not measure savings against Fi because Bill Protection caps ordinary data and speeds slow after 15GB. We did not invent a 10GB Europe travel SKU for scenario A.
Flexible pricing and eligibility were reviewed October 10, 2026 using the official sources above. Other plan tiers, travel offers, hotspot and referral examples were not refreshed by this review. More context is in our Google Fi review. Google Fi does not have a Trustpilot profile we can score — it is a US carrier, not a travel-eSIM storefront, and we do not display a Trustpilot chip for it.
BetterSIM uses affiliate links, including travel-eSIM checkouts and the Fi path on our provider page. Commissions do not change the $10/GB rate, the travel prices in the table, or the traveler-type calls. The compare templates on this site still introduce some pairs as “two travel eSIMs” or “data-only” even when one side is Fi; this guide does not repeat that label, and we are not rewriting those compare pages here.
