Receiving a text when overseas in South Africa

[GrahamR_1560849]

I seem to have a recurring issue with this service or lack of it. I am suppose to get free text to SA - they don’t work I tried the not do help desk made adjustments to the iPhone still no joy.  Is it simply pointless and should I try an alternative sim operator

@GrahamR_1560849 I wonder whether the problem may lie with the network that you are connecting to in S. Africa. Perhaps you have a poor signal. This is not down to Smarty.

I suggest doing manual network search on your phone and try each in turn.
