Google Fi
- About
Google Fi is a US-based mobile carrier built around international use, with roaming data in 200+ destinations on its higher-tier and flexible plans. It gives you a real phone number, calls and texts, so it works as your everyday line at home and abroad. Details such as speeds, hotspot allowances and per-gigabyte charges differ by plan and can change, so check Google Fi's current terms before you travel.
- Countries covered
200
- Price range
Monthly plan billed in USD; the cost depends on plan type and number of lines, and international data is either included (higher tier) or charged per gigabyte (Flexible). Check current Google Fi rates.
- Strengths
- Keeps your own phone number, so calls, texts and bank verification codes keep working abroad
- Roaming data across 200+ destinations with no extra install or purchase on eligible plans
- One bill and one plan, with no need to buy or manage separate plans per trip
- Works well for frequent travellers who also live in the US and want a single line
- Weaknesses
- Requires a US-based Fi account and monthly commitment, which does not suit one-off trips or non-US residents
- Roaming speeds and hotspot use can be limited abroad, and heavy use may be slowed or restricted under fair-use terms
- Per-gigabyte or plan-tier charges can cost more than a prepaid data-only eSIM for short, data-heavy trips
Travel eSIM providers
- About
Travel eSIMs are prepaid, data-only plans you buy for a country, region or the globe and install on an eSIM-compatible phone before you leave. They are delivered by email, and you pay only for the data and days you need. They generally do not include a phone number, so calls and texts rely on apps such as WhatsApp or on your home SIM.
- Countries covered
190
- Price range
One-off purchase per plan; prices vary by destination, data allowance and validity, and are set by each store or brand.
- Strengths
- No monthly commitment: buy a plan for one trip and stop paying when you land home
- Often cheaper than roaming for data-only use, especially on longer or data-heavy trips
- Can be bought and installed before you fly, and works alongside your home SIM so you can keep it for calls and texts
- Choice of country, regional and global plans, with plan sizes matched to trip length
- Weaknesses
- Data only in most cases, so you will not have a local number for calls or SMS verification codes
- Needs an eSIM-compatible, unlocked phone, and quality varies between brands and destinations
- Each trip means picking, buying and installing a new plan, which is a small hassle if you travel often

Verdict
Choose Google Fi if you live in the US, travel several times a year and want to keep your number for calls, texts and two-factor codes with no extra setup. Choose a travel eSIM if you take occasional trips, stay abroad for a longer stretch, use lots of data or do not have a US plan, because you pay only for what you need with no monthly commitment. Many travellers combine both: keep Fi (or any home SIM) active for calls and verification codes, and add a data-only eSIM for cheaper, more predictable mobile data. Before deciding, compare Fi's current rate for your destination against eSIM options and confirm your phone is unlocked and eSIM-compatible.
Where Fresim fits
Fresim is a different kind of option: instead of buying from one brand, travel creators and brands open their own branded eSIM store, set their own prices and keep the difference between their price and their cost. Buyers get plans by email and tap Install on iPhone (iOS 17.4+) or Install on Android (Android 10+) to set up in one step, with a QR code available as an easy way to share the eSIM or install it from another screen. Prices vary by destination and are set by each store.
Frequently asked questions
Is Google Fi cheaper than a travel eSIM abroad?
It depends on how you travel. For a short or one-off trip with mostly data use, a prepaid travel eSIM is often cheaper because you pay once and there is no monthly plan. Google Fi can make more sense if you already pay for it at home, since international data is included on eligible plans or billed per gigabyte on others. Compare Fi's current rate for your destination with eSIM plan prices before you go.
Does Google Fi work in other countries?
Yes. Google Fi offers roaming data in 200+ destinations, though the details depend on your plan. Higher-tier plans include international data, while Flexible plans charge per gigabyte. Speeds, hotspot use and fair-use limits can differ abroad, so check Google Fi's current coverage list and terms before travelling.
Can I use a travel eSIM and keep my Google Fi number?
Yes, if your phone is unlocked and supports dual SIM with eSIM. Keep your Fi line active for calls, texts and verification codes, then install a data-only travel eSIM and set it as your mobile data line. Turn off data roaming on the Fi line so you do not get roaming charges.
Do travel eSIMs come with a phone number?
Most travel eSIMs are data-only and do not include a phone number. You can still make calls and send messages through apps such as WhatsApp, FaceTime or Google Meet over mobile data. If you need to receive SMS codes, keep your home SIM active in the second slot.
How do I install a travel eSIM on my phone?
After buying, you receive the eSIM by email. On a supported iPhone (iOS 17.4+) or Android (Android 10+) you can tap the install button in the email to set it up in one step. You can also scan the QR code, which is handy for sharing the eSIM or installing it from another screen. Your phone must be eSIM-compatible and carrier-unlocked.
