@ahmad Saad, Ah, I see that you are working with R2018a. geoscatter() was introduced in R2018b, that's why it won't work for you.
In that case, use geobubble -
latitude_data= [15 -10 30];
longitude_data= [25 -10 -5];
geobubble(latitude_data, longitude_data, 5, 'BubbleColorList', [1 0 0], ...
'LegendVisible', 'off');
%specify limits
geolimits([-30 45],[-20 50])

@Dyuman Joshi
thanks again.
yes, it works.
however, i get the error:'Undefined function or variable 'geobasemap'."
it gives a grey background

Once again, geobasemap() was introduced in R2018b.
I somehow forgot to check for that before (It's getting late here haha). And I realised that and updated my above comment, just after you commented.
Unfortunately, you will have to work with gray and white.
