Buy eSIM with Ethereum: Pay with ETH for Three Networks

HelloSIM dey accept ETH for travel eSIMs for three networks: Ethereum itself, Arbitrum and BNB Smart Chain. Choose “Pay with crypto” for checkout, select ETH and the network wey your funds dey really, and send the exact amount wey dem show; dem go issue the eSIM when the payment confirm for blockchain.

For anybody wey dey keep most of their funds for ETH, that cover the main wallet setups and the most common exchange withdrawal routes. The only decision wey you really need make na which of the three networks you go use.

Three ways to pay for eSIM with ETH

• Ethereum mainnet. The original network and the one wey every wallet and exchange support. Fees, wey dem dey call gas, dey move with demand and e fit be noticeable beside small purchase.
• Arbitrum. A layer-2 network wey dem build on top Ethereum. ETH na the coin wey you hold and na also the coin wey you dey use pay fees, and those fees dey generally lower than for mainnet.
• BNB Smart Chain. Here ETH dey exist as BEP-20 token, version wey many exchanges dey offer as withdrawal option. Dem dey pay fees for this network with BNB, no be ETH.

All three dey use the same style of address, wey start with 0x, and wallet go usually show the same address for you for each of dem. That one convenient, and na also why mistakes dey happen: nothing for the address itself dey tell you which network the transfer dey travel on.

ETH also dey exist for other layer-2 networks and sidechains. If the network wey hold your ETH no dey for the payment page, no send from am. The payment page dey show the current list, wey fit change.

Which ETH network you suppose choose?

Start from where your ETH dey already. To move funds from one network go another need extra transaction and extra fees, and e hardly make sense for purchase wey be the size of travel data plan.

• ETH for self-custody wallet for mainnet: pay for Ethereum and accept the gas fee, or use Arbitrum if you don get balance there already.
• ETH for Arbitrum: pay for Arbitrum. You don hold the coin wey you need for the fee already.
• ETH for exchange: look the withdrawal screen. Exchanges dey list fee for each network, so pick whichever of the three suit you and then select that same network for the payment page.
• BEP-20 ETH for wallet: pay for BNB Smart Chain and make sure say you get small BNB for the fee.

How to buy eSIM with Ethereum: the steps

1. 1Choose your plan for the HelloSIM website or for the app. Plans price dey for euros.
2. 2For checkout, put your email address and select “Pay with crypto”.
3. 3For the secure payment page, choose ETH and then the network: Ethereum, Arbitrum or BNB Smart Chain.
4. 4The page go change the euro price to ETH for that moment and give you address, QR code and the amount.
5. 5For your wallet, switch to the matching network before you paste the address. Put the exact amount and send.
6. 6When the payment confirm, dem go deliver the eSIM to your account or the app, and dem go send the QR code by email.

Gas fees and how to get the amount exactly right

The amount for the payment page na wetin must arrive. Na you go pay gas on top am, so your balance must cover both. Two situations dey catch people.

The first na the “send max” button. If your wallet empty the balance and take gas out of am, the amount wey go arrive fit lower than the amount wey dem request, and if you send less than the amount wey dem show, the payment fit stay incomplete. Type the amount in by hand. If you send small more than wetin dem request, the order still go complete.

The second na gas setting wey too low for current conditions for mainnet. Transaction wey dey wait long time to confirm go delay your eSIM, and the payment request dey open for only 1 hour. If e expire before you don send anything, start new request from checkout. Never send go expired one.

Stablecoins for the same networks

If you get stablecoins beside your ETH, dem accept dem too. You fit send USDT for Ethereum, Arbitrum and BNB Smart Chain among other networks, and USDC for the same three, plus Polygon and Avalanche. DAI dey for the list too. The same rules apply: exact amount, exact network. You still go need ETH, or BNB for BNB Smart Chain, to cover the fee.

Stay connected after the transaction confirm

eSIM wey you buy with ETH na standard HelloSIM eSIM: data-only, you go use am together with your main SIM, you fit install am over Wi-Fi any time after purchase, and the validity go start for first connection for your destination. All sales na final, so check say your phone support eSIM and e carrier-unlocked before you pay. Everything else, including the current coin list, dem explain am for HelloSIM “Pay with crypto” page.
