About KT in South Korea

KT is one of the 3 prepaid networks operating in South Korea, with the dial code +82. Refills are denominated in KRW and settle on the carrier under 60 seconds after our payment confirms on chain.

You don't need a KT account, the South Korea MyCarrier app, a local bank or any in-store kiosk — just the phone number and the crypto. The credit shows up on the SIM exactly the same way as if you'd topped it up at a corner store.

KT mobile top-up · FAQ

Can I top up KT with Bitcoin?

Yes. Pay in Bitcoin (BTC), Monero (XMR), Ethereum (ETH), USDT (TRC/ERC/SOL), Litecoin (LTC), Bitcoin Cash (BCH), Solana (SOL), Dogecoin (DOGE), Dash (DASH), Tron (TRX) or BNB. The KT line in South Korea gets credited within minutes of your deposit confirming on chain.

How fast does the KT credit land?

Carrier-side, KT typically posts the credit within 30 seconds of our settlement message. End-to-end (you click pay → SIM has credit) it's usually 1-3 minutes on fast chains (LTC, TRX, SOL), up to 10 minutes on slower ones (BTC).

What's the cheapest crypto for a KT refill?

For small refills (under $50 USD-equivalent), USDT-TRC20, Tron (TRX), Litecoin (LTC) or Solana (SOL) keep network fees to single cents. Bitcoin works fine but BTC fees can be disproportionate for small top-ups — pick a cheaper chain instead.

Do I need a KT or South Korea account?

No. We talk to KT on the back end with the phone number alone. No MyKT portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.

Will KT or the recipient see I paid in crypto?

No. KT sees a routine top-up at the local face value (KRW). The recipient sees the new balance on their SIM. Neither sees the funding source, your email, or any other payment metadata. From the SIM's side it's identical to a corner-store refill.
