Free · To open the cardConnects to the strongest network available, on 4G/5G
The same national carriers locals use — 200+ of them, chosen per destination for signal.
One card. Every trip.
- 200+ destinations on one profile. The card goes wherever the itinerary does.
- Plans change mid-trip? Land somewhere else and it keeps working.
- Every one of the 203 launch rates is published on the coverage page. Look yours up before you go.












Every destination. One published rate.
- One published per-GB rate per destination, and your traffic is metered in megabytes.²

- Bigger trip ahead? Add a data pack and the rate drops.
What gets used first
Always the cheapest data you hold: destination pack → region pack → global pack → reward data → low-speed fallback. Your PAYG balance comes last, and only if you switch it on.
Packs, for when you want a lower rate
Destination packs
30 days1, 3 or 5GB for a single destination — roughly 20–35% under PAYG.
Region packs
30 daysOne pack across a whole region. Built for multi-stop routes through Europe, Asia-Pacific, North America or the Middle East.
Global packs
30 daysOne pack. Every standard destination.
Optional, on top of pay-as-you-go. The 30 days start the first time you connect.
The balance belongs to your account, not to one phone.
- Top up, spend or redeem, and the 24-month clock restarts.
- New phone? One free reissue per card year, then $1.99.⁴
- Changed your mind before installing? Full refund within 30 days.³
How the ONE card works
It is an account, not a plan. One eSIM holds your balance and your packs, everywhere we cover.
Open it free
Nothing to buy to get started. The card becomes the account every future trip runs on.
Top up from $5
Add credit whenever it suits you — there is a welcome surprise on your first one. What you do not spend waits for the next trip.
Land and go online
Billed by the megabyte at the destination’s published rate. No daily fee. Add a pack any time for a lower one.
Product summary
- 1Your balance stays valid as long as the account sees any activity within 24 months — top up, spend, or redeem and the clock resets. Data packs are valid 30 days from activation.
- 2Transparent per-destination pay-as-you-go rates; the full table lives on the coverage page.
- 3Uninstalled cards refund in full within 30 days. After installation the card itself is no longer refundable, but the most recent balance top-up still is, minus an administrative fee — see the refund policy. Statutory consumer rights that cannot be excluded are unaffected.
- 4One free eSIM reissue per card year, then $1.99 per swap.
- co:sim ONE card is a data-only travel eSIM, carried over third-party mobile network partners. It has no phone number, no voice service, no SMS and no emergency calling.
- No monthly fee, no daily fee, no activation fee. The card itself is free — you pay for the data you use and the packs you choose to buy.
- Data stops when your balance reaches zero. We warn you before it does, and we never advance credit or charge your payment method automatically — top up or buy a pack and you are back online.
- A pack keeps for up to 24 months before you activate it, then runs 30 days from activation — activation being your first connection inside that pack’s coverage.
- Network profile: in most destinations we attach to the strongest network available, supporting 4G and 5G NSA, with a bearer of QCI 8 (AMBR 1000/1000 Mbps) or QCI 9 (AMBR 600/300 Mbps). Real throughput depends on your device, the local partner network and roaming conditions at the time — speed is not a promise and is not on its own a ground for a refund.
- This is a pre-launch summary. The terms of service published at launch govern; after that we give at least 30 days’ notice by email or on-site notice before any material change.
- This page summarises the product. The contract in force when you buy governs, and where translations differ the English version prevails.
