Chile SMS Features and Restrictions


South America is a growing mobile messaging market, but one with many challenges. Chile is one of the major South American destinations and various filters are in place to filter and block SMS. In order to resolve this growing problem, Vonage uses adaptive routing to maximize successful delivery.

Sender ID

All Sender IDs are changed to a random numeric sender.


Adult Content

No adult content is allowed.

Political Content

No political content is allowed.


Usually direct suppliers or local aggregators do support Unicode in Chile.
Some Numeric Sender IDs offered by Vonage's 2-way service do not support Unicode.

Other Features or Restrictions

Delivery Receipts

Handset delivery reports are supported, but they are frequently delayed and are therefore not a good measure of message delivery latency.

Destination Number Formatting

All mobile numbers are required to have a digit (9) added in front of the number (behind the country code). When Vonage receives a message for this country, this digit will be added to the destination number automatically to ensure delivery.

Example: Vonage receives a message for 564756XXXXX, Vonage adds the digit 9 after the country code and sends to the operator with the destination as follows: 5694756XXXXX.

Termination with Response Functionality

Must initiate an MT first in order for MO to work.
