A carrier lookup for a Hong Kong number reads the number's format first and then its carrier record.
This is the path one lookup takes. A number can be written correctly and still sit with no carrier name on record, so the result says when the network lists none.

A Hong Kong mobile number has 8 digits after +852 and starts with 5, 6 or 9, so any other length is not a valid mobile.
These lengths come from the numbering data for Hong Kong. Hong Kong has no area codes and no leading 0, so a number reads the same at home and abroad. A few smaller mobile ranges start with 4, 7 or 8.
| Number type | Starts with at home | Digits after +852 | Written at home |
|---|---|---|---|
| Mobile | 5, 6 or 9 | 8 | 5123 4567 |
| Landline | 2 or 3 | 8 | 2XXX XXXX |
Three common mistakes make a Hong Kong number fail the check, and each one is quick to fix.
Repeating +852 adds digits.
Write +852 5123 4567 once, with the country code at the front.
Typing too few or too many digits makes a number invalid.
A mobile number has 8 digits after +852. With 7 or 9 it cannot be a valid mobile, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The lookup reads a number by the rules of the country selected above, so keep Hong Kong selected for a +852 number. Paste a number with its + and country code and the country is read from the number itself.

Can the first digits of a Hong Kong number tell me its carrier?
No. The digits help show whether a number is a mobile, since a mobile has 8 digits after +852, starting 5, 6 or 9, but they do not name a carrier. The carrier lookup shows the network a number is on now.

Not in the free result. The carrier lookup shows the ported flag for US and Canada numbers only. The free HLR lookup for Hong Kong has a Ported row for a mobile number, and it reads Yes, No or Unknown.
Why does the carrier come back as Not available?
Some numbers, landlines among them, come back with no carrier name because the network does not list one. The line type and the country still show.

No. It names the network and the line type. The free HLR lookup asks the network whether a mobile number is switched on and reachable right now.
