Guinea: SMS Guidelines
Dial Code: 224
Alphanumeric Sender IDs are supported.
For Network MTN (61104) Alphanumeric Sender IDs are only supported with registration. Without registration to this network, Alpha Senders will be overwritten to Generic Alpha Sender IDs or will NOT deliver.
The use of generic Alpha Sender IDs is not recommended. Alpha Senders should be directly related to the message content.
Please make sure to always refer to our Acceptable Use Policy for Messaging.
