To pay with crypto in the HelloSIM app on iPhone or Android, choose a plan, select "Pay with crypto" at checkout and send the exact amount shown on the secure payment page that opens, on the exact network shown. Once the payment is confirmed on the blockchain, the eSIM appears in the app, ready to install from there, and its QR code is also emailed to you.
Paying in the app follows the same rules as paying on the website. What changes is that the plan, the payment page and often your crypto wallet are all on the same phone, which makes a few practical details worth knowing before you start. This guide covers the steps, paying from a wallet app on the same device, topping up your HelloSIM wallet balance with crypto and what to do if a payment goes wrong.
How to pay with crypto in the HelloSIM app, step by step
- 1Choose a plan in the app. Pick a country, a regional plan or a Global plan. Prices are shown in euros.
- 2Select "Pay with crypto" at checkout. The secure hosted payment page opens.
- 3Choose the coin and the network. The page converts the euro price into your coin at that moment and shows a payment address, a QR code and the exact amount to send.
- 4Send the payment from your wallet or exchange. Send the exact amount, on the exact network shown, within 1 hour. Network fees are paid by you on top of that amount.
- 5Return to the HelloSIM app. The eSIM is issued once the payment is confirmed on the blockchain, and the time that takes depends on the coin and network.
- 6Install the eSIM from the app. Do it over Wi-Fi whenever it suits you. The QR code is emailed as well, so you also have a copy outside the app.
How to pay when your crypto wallet is on the same phone
On a computer you would scan the QR code with your phone. When the payment page is already on your phone, you cannot scan your own screen, so there are two practical ways to pay:
- Copy and paste. Copy the payment address from the payment page, switch to your wallet or exchange app and paste it into the send or withdrawal form. Then enter the exact amount and select the same network.
- Use a second device. If your crypto is in a wallet on another phone or a tablet, scan the QR code on the payment page with that device.
Before you switch apps, note the coin, the network and the exact amount. After pasting, compare the first and last few characters of the address with the payment page. It takes seconds, and a blockchain transfer cannot be recalled once sent.
Exchange apps need two extra checks:
- The network. Withdrawal forms often preselect a network. If it differs from the one on the payment page, change it, because a transfer on a different network can leave the payment incomplete.
- The withdrawal fee. Many exchanges take their fee out of the amount you enter. Sending less than the amount shown can leave the payment incomplete, so make sure the amount that arrives is the amount requested. Overpaying still completes the order.

Which cryptocurrencies can I use in the HelloSIM app?
The payment page lists about 100 coin and network combinations, and the current list is always the one shown there. It includes Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Solana (SOL), Toncoin (TON), TRON (TRX), BNB, Dogecoin (DOGE) and Monero (XMR), plus Tether (USDT) on eight networks, among them TRON (TRC-20), Ethereum (ERC-20), BNB Smart Chain (BEP-20), TON and Solana, and USD Coin (USDC) on five. The minimum for a crypto payment is €1.00.
For a payment from a phone, the practical choice is usually a coin already in your wallet app, on a network that app supports.
How to top up your HelloSIM wallet with crypto in the app
The app also lets you add money to your HelloSIM wallet balance with crypto, from €1.00. The process mirrors checkout: select "Pay with crypto", pick a coin and network on the secure payment page, and send the exact amount within the hour.
A balance is handy once you are travelling. You can make one crypto payment while you are on reliable Wi-Fi, then use the balance later for a new plan or more data, without starting a blockchain transfer at the moment you need it.
Where does my eSIM appear after paying with crypto?
Once the payment is confirmed on the blockchain, the eSIM appears in the app and the QR code is emailed to you. HelloSIM does not promise a specific number of minutes for confirmation, so pay before you travel, not at the gate.
Closing the app does not cancel a payment you have already sent. When you come back, the eSIM is in the app once the payment is confirmed, and you can install it from there over Wi-Fi. Validity starts when the eSIM first connects to a network at your destination, not on the day you buy it, so installing it a few days early is fine.
What if my crypto payment in the app goes wrong?
- The request expired. A payment request stays open for 1 hour. Never send to an expired request; start a new one from checkout in the app.
- You sent too little. An underpayment can leave the payment incomplete. Contact HelloSIM support with the transaction ID.
- You used a different network. That can also leave the payment incomplete. Contact support with the transaction ID.
Blockchain transfers cannot be recalled, and all sales are final once an order is paid, so check the plan, the amount and the network before you send.
What you need to pay with crypto in the app
- The HelloSIM app on an iPhone or Android phone that supports eSIM and is carrier-unlocked
- A wallet or exchange app with a supported coin, plus enough for the network fee
- An email address to receive the QR code
- Wi-Fi to install the eSIM
Stay connected with crypto from your phone
Paying in the app takes the same care as anywhere else: the right coin, the right network, the exact amount and the one-hour window. Get those right and the eSIM shows up in the app, ready to install before you leave.
