Buy an eSIM with Solana: Pay with SOL or USDT on Solana

You can buy a HelloSIM travel eSIM with Solana by choosing "Pay with crypto" at checkout and selecting SOL on the payment page. If you prefer to pay in a stablecoin, USDT on the Solana network is accepted as well.

Solana wallets are built around quick, small transfers, which suits a purchase like mobile data. Here is how the payment works, what is and is not accepted on Solana, and what to check before you approve the transaction.

How to buy an eSIM with SOL

1. 1Choose a plan for your destination on the HelloSIM website or in the app. Country, regional and global plans are all priced in euros.
2. 2At checkout, type in the email address that should receive the eSIM and select "Pay with crypto".
3. 3On the secure payment page, pick SOL. The euro total is converted into SOL at that moment.
4. 4Scan the QR code with your Solana wallet, or copy the address and the amount into it.
5. 5Approve the transfer for exactly the amount shown.
6. 6As soon as the payment is confirmed on the blockchain, the eSIM appears in your account or the app and its QR code is emailed to you.

Stablecoins on Solana: what is accepted

USDT on Solana is on the list, so if you keep Tether in a Solana wallet you can pay with it directly. Select USDT on the payment page and then Solana as the network.

USDC is a different story. At the time of writing, USDC is listed on Ethereum, Polygon, BNB Smart Chain, Arbitrum and Avalanche, and Solana is not among them. The payment page shows the current list and it can change, so check there first. If USDC on Solana is not offered, do not send it to an address meant for another coin or network. Pay with SOL or with USDT on Solana instead.

Whichever token you send, the Solana network fee is paid in SOL. A wallet with USDT and no SOL cannot complete a transfer, so keep a small SOL balance.

What to check before you approve the transaction

• The amount. Sending less than the amount shown can leave the payment incomplete. The network fee is yours to pay on top. If you overpay, the order still completes.
• Your SOL after the fee. Using a "max" button can leave the transfer short once the fee is taken. Enter the amount yourself.
• The network on exchange withdrawals. Exchanges sometimes offer SOL on more than one network. Choose Solana, to match the payment page.
• The address. Use the one on the page in front of you, and compare the first and last characters after pasting.
• The clock. A payment request stays open for 1 hour. If it expires, start again from checkout and never send to the expired request.

How fast is delivery when you pay with Solana?

HelloSIM issues the eSIM when the payment is confirmed on the blockchain. Solana is generally known for confirming transfers quickly and for low fees, which is a large part of its appeal for everyday payments. Even so, any network can slow down under heavy load, and HelloSIM does not promise a specific number of minutes.

If you are sending from an exchange, the exchange's own processing comes first, and that is often the longer wait. The practical advice is the same as for any coin: buy before you travel. The plan's validity starts when the eSIM first connects to a network at your destination, so an early purchase costs you nothing.

Using a wallet balance for repeat purchases

If you top up often or buy plans for several trips, you can add money to your HelloSIM wallet with SOL or USDT, starting at €1.00, and pay for eSIMs and top-ups from that balance instantly. That keeps the blockchain step to a single transfer and leaves later purchases free of any waiting.

Stay connected on arrival

The eSIM you get is data-only and runs alongside your main SIM, so you keep your usual number. You can install it over Wi-Fi any time after purchase, provided your phone supports eSIM and is carrier-unlocked. All sales are final, so confirm the destination and your phone's compatibility first.
