Peru SMS Features and Restrictions

Sender ID

Telfonica/Movistar (71606): Sender ID on all messages will be generally changed to a local number to ensure delivery.

Nextel (71607): Generally Sender ID is dynamic, but some Sender IDs will be overwritten to ensure delivery.

Claro (71610): Claro is filtering alphanumeric and national numeric Sender IDs. All SMS sent with those Sender IDs will not be delivered. It is recommended to use a numeric Sender ID with the international number format to reduce the risk of being filtered.

Only messages in English and Latin characters are supported.

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