@Ockie -We have been assured by a Vodacom Eclo staff that the company is working on the issue.
QUOTE- Vodacom remains committed to supporting new and innovative ways of messaging, including RCS. While some Android devices already support RCS, Vodacom and Google are in discussions and are yet to sign an agreement governing some of the terms to support customers. Vodacom is also engaging other global suppliers to support both Android & iOS, to drive RCS adoption in the future. -UNQUOTE.
Remember that connection by Vodacom Mobile Data is the problem.
