Backup Internet is always handy. Hence why I don't have 3G with the same DSL provider.
My backup 3G connection is with telecom, and the problem didn't affect that.Just didn't want to use it too much due to data costs. But I guess it is ok for just email. But don't think I can tether my desktop to my S3 phones 3g connection, as the desktop isn't wifi, at least I haven't tried to do it. Possibly it can be done via the USB cable.
