Re: Oh well
My roaming in France on 3mobile didn't work. Called their support number from my wife's Voda but no matter how many times I selected the required network it failed to connect. So no calls or data plus nearly an hour of holiday wasted.
The second I drove into Switzerland *BING* text message "Welcome to Switzerland, feel at home with no data charges". Same for Italy and then later Austria. I switched roaming off while driving through Germany and Belgium, and the gremlins must have been evicted by the time I got back to France as it worked perfectly.
For anyone who regularly visits any of the covered countries it's a real plus. I'd go SIM only next time though - they're not the fastest to get updates out to their locked handsets.
