About CSL/1O1O in Hong Kong
CSL/1O1O 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 CSL/1O1O 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.
CSL/1O1O mobile top-up · FAQ
Can I top up CSL/1O1O 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 CSL/1O1O line in Hong Kong gets credited within minutes of your deposit confirming on chain.
How fast does the CSL/1O1O credit land?
Carrier-side, CSL/1O1O 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 CSL/1O1O 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 CSL/1O1O or Hong Kong account?
No. We talk to CSL/1O1O on the back end with the phone number alone. No MyCSL/1O1O portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will CSL/1O1O or the recipient see I paid in crypto?
No. CSL/1O1O 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.
