Hi. My name is Jorge, and I’am actuallyu working at Sayme Corp, Cantabria (Spain)
We have a Business Opportunity, with a Hong-Kong Client, and we want to do
some test on Narrow Band IoT Network, specificly with 3 HK. 3 Hong Kong is operated by [Hutchison Telecommunications Hong Kong], a subsidiary of [CK Hutchison].

Why do you need it? Correct APN should be sufficient.
All the best:
you can see it in online databases as https://www.mcc-mnc.com/
but i recommend to read it from your SIM Card using a modem and a couple of AT commands or with an Android smartphone and an app.
sometimes M2M SIM Cards are different as consumer SIMs, for example Global SIM with MCC=901.
In my devices I implement a small database with MCCMNC to APN pairs. At power-up, i read the MCCMNC from SIM card and look for the potential APNs to use.
To build the db and keep it updated I use android sources at:
