UK communications regulator Ofcom has opened an investigation into Vodafone and EE for allegedly giving inaccurate data about mobile coverage areas.

The two investigations were opened on 1 October and both will examine "whether there are reasonable grounds for believing" that each operator "has failed to comply with its obligations under sections 135 and 136 of the Communications Act 2003".
