China 106 SMS
Domestic standard 106 SMSDirect routes into China Mobile, Unicom and Telecom for one-time passwords, order notifications and marketing alike, submitted from the console or triggered over the API.
Fixtures and campaigns come with a window. Only a stable route guarantees that the message arrives while the window is still open.
The growth bottlenecks these platforms run into around acquisition and retention.
Ordinary advertising channels restrict this subject matter heavily, leaving few ways to reach anyone.
Campaign details do not land, and both participation and conversion fall short.
A wobbling route makes an entire batch miss kick-off or the opening window.
Without a sustained way to reach people, new users rarely settle into active ones.
Acquisition, promotion, top-ups and win-back — the full operating cycle.
