At the moment our SIMS are limited to one package per SIM, however we would definitely like to offer some sharing options in the future. Let's hope we can get that right for you and other clients who have asked for this :)
For the moment at least, you can use our Free SIMS to have multiple devices with their own Mobile Data and maybe purchase small packages (like 250MB for just R29pm) and then topup when you need to on which device is running out of data. Our ClientZone gives you the awesome ability to rename each SIM with a custom name, so you don't need to remember complex details. We'll also send you email or test alerts if any of your data SIMS are close to running out of data.
