Polygon na network wey anybody wey dey use Ethereum-style wallet don sabi, and e dey give you one network with three ways to pay. This guide dey cover wetin concern Polygon specifically: which coin to choose, why the address format dey make network mistakes easy, and why stablecoin payment for Polygon still need small POL.
Which Polygon coins you fit use buy eSIM?
Three options for the payment page dey run for Polygon:
- Polygon (POL): the network own coin. POL don replace MATIC, so some old wallet screens and exchange menus fit still dey show the old name.
- Tether (USDT) for Polygon: one of the eight networks wey HelloSIM dey accept for USDT.
- USD Coin (USDC) for Polygon: one of the five networks wey HelloSIM dey accept for USDC.
The payment page dey always show the current list of coins and networks, and e fit change. Pick any of the three wey you don get for Polygon already; to first move money from another network go just add more steps.
POL or stablecoin: which one you go send?
Every plan price dey for euros, and the payment page dey convert the euro price to the coin wey you choose for the moment wey you pay. Dem design USDT and USDC to follow the US dollar, so e easy to guess their figure before you start. For POL, the figure depend on POL rate for that moment. For every case, send the number wey the page show, no be the one wey you calculate yourself.
The real difference na the fee. When you send POL from your own wallet, the network fee go comot as POL from the same balance. When you send USDT or USDC for Polygon from your own wallet, dem still dey pay the fee with POL, so the wallet need small POL balance plus the stablecoin. If you no get am, the transfer no go even fit send.

Why Polygon network mistakes dey happen so easily
Polygon addresses dey start with 0x, exactly like addresses for Ethereum, BNB Smart Chain, Arbitrum and Avalanche. Wallet or exchange go accept the payment address for any of those networks without complain, because e look correct for all of dem. Na why you must check the network with purpose: transfer for different network from the one wey dem show fit leave the payment incomplete, and blockchain transfers no fit reverse once you don send am.
Three habits dey stop most wahala:
- For browser or mobile wallet, check say the network selector dey show Polygon before you paste the address.
- For exchange, select Polygon for the withdrawal network list, even if dem don preselect another network.
- If your POL or stablecoin dey for Ethereum, no send am from there go payment request wey dem create for Polygon.
Two kinds of USDC for Polygon
Polygon wallets dey sometimes show two USDC balances: native USDC and one older bridged version, wey dem dey often label USDC.e. Dem be separate tokens. If you no sure which one you get, ask HelloSIM support before you start payment request, no be after you don send the transfer.
Fees, amounts and the one-hour window
Na the sender dey pay network fees, on top of the amount wey dem show. When you dey pay from exchange, check whether dem dey remove the withdrawal fee from the amount wey you type. If dem dey remove am, wetin reach go less than wetin dem request, and if you send less than the amount wey dem show, the payment fit stay incomplete. If you overpay, the order still go complete.
The minimum for any crypto payment na €1.00. Payment request dey stay open for 1 hour; if e expire, start new one from checkout and no ever send go the one wey don expire.
