We are using Adaptive Routing throughout Hong Kong which will ensure several routes are constantly being tested and the optimum one will be used for your traffic.
- For ChinaUnicomHK (45407) and ChinaMobileHK (45412):
- All senders will be replaced by local Hong Kong numbers to ensure delivery, as alpha sender IDs are often problematic for 1sim2numbers subscribers.
- For CSL (45400) , Hutchison (45404) , SmarTone (45406) and PCCW (45416):
- Dynamic alpha senders within 3-11 characters length are supported,
- Non-alpha senders are replaced by local Hong Kong numbers or “SMS” as an alpha SenderID to deliver.
There are no additional content restrictions beyond those in our Acceptable Use Policy
Concatenated SMS are supported on all Hong Kong networks.
Other features/restrictions of note:
Reliable delivery receipts are supported on all Hong Kong networks.
