What kind of senders can be used and what usage limits do senders have?

The origin of a message is the sender field. When messages are sent from LabsMobile platform a different sender can be chosen for each sending whether you send it from the application WebSMS or from API.

The maximum length of the sender is 11 characters and only standard letters and numbers ([a-zA-z0-9]) are permitted. If the sender is only numeric then the maximum length permitted is 16 digits.

However, customization or change of the sender is only available for some countries due to restrictions and usage limits of the telephone operators. In countries where this benefits are restricted messages will be received through a fixed or a random number that can be a Shortcode number or in international format. Countries with these restrictions can be checked on the Services and credits by country section and also on the sending forms alert.
