Sender ID

Dialog (MCCMNC:41302): Numeric Sender IDs are not allowed and non-registered Sender IDs will be overwritten to any generic Alpha Sender IDs.

Due to heavy filtering by the operators, we recommend registering your alpha Sender IDs and contents with us towards Dialog to improve delivery quality towards these networks. Please contact your account manager or support team for more details if you would like to register your traffic.

Airtel (MCCMNC: 41305): Non-Alpha Sender IDs will be overwritten to any generic Alpha Sender IDs.

Other networks: Sender IDs towards the rest of Sri Lanka networks are fully dynamic but subject to changes at operator sides.

It is recommended to send messages with alpha Sender IDs that reflect your brand name (Use sender = {your brand}) towards Sri Lanka. This is to prevent your messages from being filtered by the local operators due to Sender ID being too generic or number senders which are not allowed towards them.
