Hey Thebolo, below are the possible causes
- The tablet was taken up on a contract agreement and the original owner has defaulted or breached the contract in one way or the other. This then led Vodacom to blacklist the device.
- The Vodafone Smart tab 3G was bought secondhand from a third party who got it through an unlawful way (that got the police officials involved) and hence its IMEI has been blacklisted.
- Lastly, one or more electronic network dependencies (on the tablet's PCB) may have sadly failed.
Resolving any of the three possible causes will either ways involve contacting Vodacom's Customer Service center.
