Sri Lanka SMS Features and Restrictions

Sender ID

Mobitel (MCCMNC:41301): Dynamic alpha Sender IDs are supported. Numeric and generic Sender IDs are not allowed towards Mobitel.

Dialog (MCCMNC:41302): Numeric and generic Sender IDs are not allowed towards Dialog. Registration of alpha Sender IDs is possible to avoid your messages being filtered by the operator. Contact your account manager for more details if your SMS volume exceeds 10k per month.

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 are not allowed towards them.


There are no additional content restrictions beyond those in our Acceptable Use Policy.
