It’s the second most utilized mobile company in Europe. It was founded in 1985 by John Carrington and sold later in 2005 to Telefonica. O2 offers great coverage both in 2g and 3g, and added to this – the 4g increased its efficiency in the last period.  Although we review it positively, we suggest you do a coverage test in the area you are based before going for it. In spite of these pros, exactly as we stated for EE, this brand is much more expensive compare most of the rest. Especially nowadays when companies play with bundles and add-ons, this is a brand that keeps its prices. Here’s the best 2017 deal, selected by us for you:
