I think that whether you can jump on the "voda rule" bandwagon depend on your location. I jumped on that very bandwagon myself (i never enter in to any more than the 30 day deals) thinking that voda rule - I geeked out on checking network operator maps for a while, which helped convince me that voda rule, however, when I put real world experience next to what their coverage maps suggest for my areas of working and living I am greatly disappointed. I use an iphone (currently) so my signal isn't as good as it could be anyway, but voda certainly dont help here. Voda customer services I never had a problem with, but for coverage here, for me its Three (believe it or not) and o2 - with O2 I get a 3G signal nearly everywhere I go (even when their map says I wont) those two networks arent without their own faults in other areas though.
