Premium number is a 1900 or 1902 number that has a 'tariff' attached and you will be charged the amount set for this service. These tariffs can be 'timed' (per minute), or they can be 'fixed' (per call)
We don’t set the costs for calling these numbers, but rather the owner or provider of these numbers does and on-passes these costs to us and then to our customer.
Premium calling is not available on SpinTel Phone (VoIP)
For mobile, you can enable this feature by following the steps below:
3. Select the mobile service (from the list on the left menu if you have more than one) and click on Configure.
4. Enable Outgoing Calls to International & Premium Numbers and click Update at the bottom page to save the changes.
On the other hand, Premium SMS is used for messaging that charges a premium price to the end user per sent SMS
The most known use cases for premium SMS is when the numbers are used for charity or voting activities, when you want to purchase content or services such as ringtones and games. For example, in case of a natural disaster, you can easily send an SMS message to a short code in order to donate funds to help people in need.
To enable premium SMS, as shown above go to My Account > Configure > SMS Option > Premium SMS
It can take 48 hours for the feature to be enabled.
