as the title says.
i'm on vodafone at the mo, but it turns out the 30p call/14p text rate is pretty shtty (i just got the sim/phone to have for emergencies, only been using it a lot lately due to family health issues). the other issue is the credit expires if you don't use it, which has caught me out in the past. been to a couple of review sites and there seems the usual flood of positive and negative for everything so i thought i'd ask here instead of trawling through tons of other sht.
i'm looking for decent coverage, rates and preferably non-expiring credit. be using phone and text, internetting will be extremely doubtful, overseas usage not an issue unless i get back to the USA in the future - the way money is, that don't seem likely :-D
