If you earn and spend in crypto, you can run your mobile data the same way. HelloSIM sells travel eSIMs for 190+ countries, plus regional and global plans, and accepts crypto both at checkout and for adding money to a HelloSIM wallet, so a long-term traveller never needs a bank card to stay online.
For most nomads the setup that works best has three parts: a plan that matches how often you cross borders, a wallet balance funded with crypto, and top-ups on the same eSIM as you go. This guide walks through each.
Choosing an eSIM plan when you have no fixed route
Travel eSIMs are sold by coverage area, and the right one depends on how you move.
- Country plans suit a long stay in one place, such as a few months based in a single city.
- Regional plans cover several countries in the same part of the world, which fits overland routes and frequent short hops.
- Global plans make sense when the next destination is not decided yet, or when your year spans more than one continent.
Whichever you pick, the eSIM is data-only and works alongside your main SIM, so the number your bank, clients and family use stays in the phone. Validity starts when the eSIM first connects to a network at the destination, not at purchase, which means you can buy the next plan before you leave the current country.
How to pay for an eSIM with crypto on the road
At checkout, on the website or in the iPhone or Android app, select "Pay with crypto". A secure payment page lets you choose from about 100 coin and network options and shows an address, a QR code and the exact amount, converted from the euro price at that moment.
The coins nomads tend to hold are all there: USDT on TRON, Ethereum, BNB Smart Chain, TON, Solana, Polygon, Arbitrum and Avalanche; USDC on Ethereum, Polygon, BNB Smart Chain, Arbitrum and Avalanche; plus BTC, ETH, SOL, LTC, TRX and many more. Send the exact amount on the exact network shown within the 1-hour window, and HelloSIM issues the eSIM as soon as the payment confirms. You will see it in your account or the app, and the QR code comes by email too.

Keep a wallet balance for the moments that cannot wait
A blockchain payment needs a confirmation, and HelloSIM does not promise how many minutes that takes. That is fine when you are planning ahead. It is less fine when your data runs out in the middle of a client call.
The HelloSIM wallet solves this. You add money to it with crypto, from €1.00, at a time that suits you. From then on, eSIMs and top-ups are paid from the balance instantly. In practice:
- 1Once in a while, when you are on good Wi-Fi and not in a hurry, send a crypto payment to add money to your wallet.
- 2When you need a new plan or more data, pay from the balance.
- 3Add money again before it runs low.
This also means you pay a network fee once per wallet top-up, not once per purchase, which adds up when you buy small amounts of data often.
Top up the same eSIM as you go
You do not need a new eSIM every time your data runs out. More data can be added to the same eSIM later, which keeps your phone free of a growing list of old eSIM profiles and saves you from repeating the installation.
An account is what makes this easy: it lets you manage your eSIMs and top up from one place. Guest checkout is fine for a one-off trip, but anyone travelling for months will want the account.
Habits that save trouble on a long trip
- Buy before you cross the border. You need an internet connection to pay and to install, and airport Wi-Fi is not always dependable.
- Use a stable connection for crypto payments. A payment request is only open for 1 hour, and an expired one must never be paid. If a weak connection costs you the window, begin again from checkout.
- Match the network. Sending on a different network from the one shown, or sending less than the amount shown, can leave the payment incomplete. Network fees are paid by you on top.
- Check the phone. It must support eSIM and be carrier-unlocked. This matters if you replace your phone mid-trip.
- Choose carefully. All sales are final, and an eSIM cannot be refunded once delivered unless there is a verified technical fault HelloSIM cannot resolve.

Stay connected wherever you set up next
A regional or global plan, a wallet balance and a habit of topping up early are enough to keep a crypto-funded life online without a bank card in sight. Sort the next country's data before you leave this one.
