CTM prepaid (e.g. Chill card)
Number-keeping SIM- Network
- CTM
- Price
- Top-up vouchers of MOP$50 / MOP$100; some cards’ data packs don’t expire
- Keeping the number
- CTM (official): a top-up automatically extends the card’s validity; once expired, the balance and remaining usage aren’t refunded. The official page doesn’t state days per top-up — a local guide says a minimum MOP$50 top-up adds about six months.
- ID check
- CTM (official): ID must be shown to register when buying; since 21 November 2025 Macau ID holders can register at most six prepaid cards. A local guide lists accepted IDs: Macau or Hong Kong ID, mainland Chinese ID, passports and other entry documents
- SMS & calls
- Chinese guides: in mainland China, enable roaming and manually select China Mobile or China Unicom, then follow the guide’s activation steps; check SMS charges with CTM
Pros
- About MOP$50 every six months keeps it
- Mainland Chinese ID accepted
Watch out
- Balance is forfeited and the number reclaimed on expiry — don’t forget to top up
- Days added per top-up aren’t clearly stated officially
