I have poor coverage at home and I have tested 2 other locations within 2 miles of home on many occasions, with 3 different phone models . All locations are listed on the 3 coverage checker as excellent for 4g. Coverage is in fact non existent- you can’t make a phone call or a basic data operation like fetching an email. When I raised this with 3 they said the coverage is excellent because the coverage checker says so!! Does any authority check 3s claims or can 3 just lie about coverage with impunity?
The networks work on postcode are and not individual addresses. If you use the OFCOM checker they go down to the individual postal address. I checked various addresses in my postcode and mine was only 3g while others were 4g and 3 gave me a decent discount for the duration of my contract as they could not guarantee getting 4g to my property.
OFCOM make their API available for free but 3 choose not to use it. Why not?
