You probably take Vodafone's 4G network for granted when on home turf, only to be saddened by slower speeds when travelling further afield. Well, Vodafone wants to make sure you get full use of your phone's LTE radio while abroad, and after announcing a bunch of new countries where 4G roaming is supported a few months ago, it's added almost as many to that same list today. Of the 17 new countries that make up the now 40-strong list, Japan, Mexico and Saudi Arabia are arguably the most notable, though you can have a gander at the full roster after the break. As you may already know, Vodafone lets customers use their normal voice, text and data allowances abroad for either £3 per day in Europe, or £5 per day everywhere else. And if you're travelling to any of the newly added countries over the holiday period, consider today's news an early stocking-filler.
