It seems to work ok over a PPTP VPN for RDP purposes. Not sure if our remote end forces a different MTU or not. I remember someone doing some work on this to get Vodafone to not drop the connection. I haven't tried it past that much. I can whip an OTG keyboard/mouse into the thing and use it as an ssh terminal for the interesting bits with connectbot so don't need the tether facility. My ThinkPad has a 3G modem in it which I don't use any more - it was on Vodafone. GG are pretty good. They went down a couple of times in the last couple of years for a few hours but comms were pretty good about it. Never had any other problems with them. Data bandwidth and latency is pretty good on 3G (HSPA+). I've pulled a huge amount of data in a month without a problem. Calls are reliable and clear and you can crank up and down your free bits every month. To be honest I probably wouldn't ever hit another PAYG or contract provider again. I just buy SIM free handsets now on a whim, use them for a year, sell them if they're ok or repair them away if I break them at cost. Up £400-500 a year on my old O2 contract.
