Important TIPS on Sender Identification

All Regular Vodatext Account Users have the option to set up their Sender Identification (Name/Number) only once. So, please use caution before you choose your Sender Name/Number. Once configured, requests for change of Sender Identification shall not be entertained, unless it is deemed as really genuine case by Vodatext

Some Networks/Operators do not grant the facility of a Dynamic Sender Identification, meaning each Sender Identification has to be specially approved by them before a message, bearing that Sender Identification, can be transmitted through their Network. This has been implemented to counter spam to a certain extent.

All API/SMPP Account Users, who have the option to dynamically change the Sender Identification, are requested to please get the list of all possible Sender Names/Numbers approved before they start sending out messages. Else, there could be a possibility of messages not being delivered.


The Sender Identification is not a guaranteed feature and may be changed by Vodatext or its Service Providers' Networks with/without notice to suit the requirement of the various technologies/ networks/ regulatory bodies etc.
