I stupidly made the decision to move our business phones to EE away from Three based on their supposed coverage,
With Three, most places I went always has 3G as a minimum and patchy 4G coverage, consistent speeds 8-10Mbps and for an overseas call centre pretty good.
With EE I find I'm dropping back to edge 2G quite frequently, business Supoport staff are total garbage, the 4G coverage is better agreed but the speeds are some times non existent.
My commute along the A1 every morning I could stream Spotify with Three, with EE I lose signal completely for a five mile stretch and this is a fairly busy stretch around Cambridgeshire.
Massively regretting the decision now.
