I'm using KeepGo as a backup internet connection if my main line goes down. I initially intended to use local mobile provider but KeepGo was interesting because there was no monthly fee (I don't want to pay for something I don't use - or use only occasionally). Installation itself was kind of troubled: I was using Teltonika RUTX09 mobile router. It took me more than an hour to configure it, for some reason mobile link connected and then dropped connection. Message log showed that I was banned from the network - no idea why. Anyways, after some time (I just left it running) it started working normally with all three providers that are available in my area. Connection speed is something I was expecting to be better. I'm currently getting ~10-15/6-10 on all three mobile providers. Local card (A1 network, HoT) gives me ~50-100/10-15 on the same network. Upload is something that I can live with for a backup link (if it stays that way), but download could be better. All in all - it works, but it's not exactly what I was hoping for.
