Voip sim card setup and use guide

The vivi® voip sim is a revolutionary new convergence technology that blends your mobile phone service and voip telephone system.

Voip sim cards work natively in a mobile phone and do not require the use of software, wifi or mobile data to carry the calls.  Calls to and from the voip sim are seamlessly passed from the mobile operator (o2) to our network.  Calls are handled directly by vivi®, and enabled with our standard telephone system features and benefits.

vivi® voip sim cards behave as extensions of your vivi® voip telephone system, enabling services including –

  • call recording

  • remote call monitoring (calls on the sim can be remotely monitored by an administrator on your system)

  • call transfer

  • call hold

  • conference call

  • pause call recording

  • free calls between the sim card and other extensions on the phone system

  • call internal phone extension numbers directly.

  • display your business telephone number as the outbound caller ID, instead of a mobile phone number.

One Bill

Why complicate life with bills from multiple suppliers?  vivi® voip sim cards appear on your monthly vivi® invoice, just like the rest of your voip phones, eliminating the need for bills from other mobile phone companies.

Getting set up

  1. Insert your new voip sim card in to any unlocked mobile phone that uses either the full sized or micro sim card slot.  

  2. Turn on your handset and wait for the network to register.  Your are ready to make and receive calls.
