If you use PTminder to send out automated SMS reminders to your clients, you can change the sending name/number that it comes from**. 

By default, this name is "Reminder", it is what the clients will see as the 'From Name' when they receive an SMS reminder on their mobile phone.

To change this Sender ID, for example to your own business name, head over to your 'Settings' then Notifications area, 'SMS Text Reminders':

** There are local restrictions depending on the country, so it's possible that your Sender ID may be overwritten to ensure the message is delivered. Maximum of either 11 characters or 15 digits is supported.
