As this thread intends, I'm going to give some feedback on this service. I've been using the device as a secondary sim in my mobile device. Works great at home, unfortunately not at my work in Bryanston

. Surprisingly according to their online map I should have spotty coverage at home and full coverage in Bryanston.
What's strange though, there is no coverage on my cellphone elsewhere around that part of Bryanston despite it being covered according to the website map. I don't know, maybe their map is incorrect or some other signal is interfering (doubtful).
I'm back to using my primary sim data full time as a result, oh well.
