There are T-mobile locations shown around here.
I'd be more impressed by the Sitefinder if it didn't have me living about 50 yards from a non-existent four miles by three-quarters of a mile lake, and not have the names of 3 of the nearest 4 villages in the wrong places. Zoom out and the name of a part of one suddenly becomes the name of the cluster
But I found out why 3 coverage improved here so much, going from 3g only about 200 yards away to full strength on the meter - they've added theirs to the T-mobile 3g site just over half a mile away
And Sitefinder doesn't explain why O2 took away their nearest 3g site about a year ago, and it was never on the map anyway
I was very kindly placing data onto the Google Map when I found this on the Ofcom site...it actually shows T-Mobile data!
I found T-mobile information! Success.
Dan, could you add a T-Mobile logo to the map?
