模板要先加白名单。
China SMS Template Whitelisting
Chinese mobile networks have very strict regulations about the time of day
and content that can be sent in messages to handsets on their networks.
Messages are often randomly selected for manual review, causing delays and
possibly a disruption of service. Customers regularly sending messages to
China should submit SMS templates of their anticipated message content for
whitelisting with local operators.
Messaging Limitations
Due to the tight regulations in China, there are a number of limitations to
be aware of:
All messages - even those based on whitelisted templates - will have a “
signature” added to the beginning or end of each message. | w*******g
发帖数: 9 | 2 Calling Limitations to China
Due to strict spam monitoring and regulations on communications terminating
to China, calls with short durations (under 3 minutes) have a high chance of
being blocked. This is a universal behavior for all international traffic
terminating to China, and is not something unique to Twilio’s platform.
To remain compliant with these regulations, access to China has been removed
from the Geo-Permissions page. Going forward, enabling calls to China will
require vetting before access is granted.
Enabling Voice Calls to China
If your calls have an average duration of over three minutes and you are
interested in sending traffic to China, your use-case must be qualified to
meet the following guidelines:
No calls allowed with a duration shorter than 3 minutes
No unsolicited marketing calls
No high volume of repeated calls from the same origination (From) Number
within a rolling hour
No calls allowed from invalid, modified, spoofed or restricted origination (
From) Numbers
Calls must be sent from an international, non-China number when making calls
to China
Please reach out to your Technical Account Manager or contact our Sales team
to discuss further. |
