Spark and Mobiles

HI Can anyone assit. We use spark to message around the office but also want to message our drivers. What mobiles shoul we be looking at that work well with spark

Spark is not designed to run on mobiles. And if by any chance you’ll be able to run it on a mobile device (it needs java), it will need a lot of RAM, and so probably be very sluggish. I suggest to search for other jabber clients for mobiles.
