(1) install an APP (iOS and Android) called Huawei HiLink.
(2) insert a SIM (any SIM will do) in the Huawei hotspot, turn the hotspot on.
(3) Use your phone to connect to Huawei's WiFi (Settings..WiFi..)
(4) invoke HiLink.
(5) follow the graphics instructions below.
Note for Hong Kong use:
For most Hong Kong carriers, you need to dial a special code to activate data. Huawei E5776s-32 cannot do dialing, hence Mobile Hotspot is a bad choice for Hong Kong CSL or PCCW, however, Mobile Hotspot can still be used with great pain in Hong Kong, but only after some excessive geeky tweaking.
