The best part about this service is that it's free! I have used other services like O2, Vodafone etc but none of them are as good or cheap compared to BRIOINFOTEL which offers great value for money with no hidden costs at all!! There isn't anything in particular i dislike so far however if you're looking into using one then try out brioinfotele first because they offer excellent customer support when needed unlike some providers who only reply after hours/days later. If your business requires internet access anywhere around Europe than use BIroinfothelll rather its very affordable. !
