Provide 24/7 support to subscribers #
Your customer support for a subscriber who needs to suspend their phone service and blacklist their handset should be 24/7/365.
Out of hours support to subscribers can be provided by a well-trained third party. The Gamma Portal has a screen called “Mobile Support – Third Party Service Search”, for which a login can be set up, and this will ensure that the third party can only carry out a suspend service / blacklist handset, and not make any other changes to a subscribers phone service.
Lost Handsets – Not Blacklisting Handset #
The following support should be available to a subscriber as 24/7 support.
In some cases your customer may lose their handset and want to bar their service but not bar (Blacklist) their handset. This is normally when a customer leaves their handset on a bus/ train or if they think they will have a good chance of finding it again. Once a handset is blacklisted it takes a minumim of 48 hours to lift. By barring the service only, the customer will be able to use it as soon as possible once they have the handset back in their possession.
To Bar the service only please follow the steps below:
- Select Mobile Number within Service Management screen
- Select Suspend Service
To Unbar the service only please follow the steps below:
