EE

✓ Legit
✓ 6 ! 4 ✗ 0
EE is the UK's largest mobile network by subscriber count and a fully legitimate, Ofcom-regulated telecoms provider owned by BT Group. It operates at scale with strong coverage credentials, but it consistently attracts high volumes of complaints around billing errors, customer service quality, and exit charges. Consumers should go in with eyes open — EE is not a scam, but it's not a frictionless experience either.

O2 is one of the UK's largest and most established mobile networks, fully regulated by Ofcom and backed by parent company Telefónica. It serves tens of millions of customers and offers strong consumer protections including clear contract terms and a published complaints process. Coverage gaps in rural areas and mixed customer service reviews are the main watch-outs, but there are no serious legitimacy concerns.
