About 3 HK in Hong Kong
3 HK is one of the 4 prepaid networks operating in Hong Kong, with the dial code +852. Refills are denominated in HKD and settle on the carrier under 60 seconds after our payment confirms on chain.
You don't need a 3 HK account, the Hong Kong 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.
3 HK mobile top-up · FAQ
Can I top up 3 HK 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 3 HK line in Hong Kong gets credited within minutes of your deposit confirming on chain.
How fast does the 3 HK credit land?
Carrier-side, 3 HK 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 3 HK 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 3 HK or Hong Kong account?
No. We talk to 3 HK on the back end with the phone number alone. No My3 HK portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will 3 HK or the recipient see I paid in crypto?
No. 3 HK sees a routine top-up at the local face value (HKD). 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.
