I have a pic of the cell somewhere if I can find it.
Yeah, mast originally had it's coverage skewed towards the call Centre and even though you can clearly see it from the A38 there was only a whiff of signal for maybe a 100 metre stretch. You had to turn off and get closer to get a signal.
Now (for anyone who knows where the Tesco store is) it almost covers down to Lee Mill and nearly to the brow of the hill before you drop down into Plymouth. About a mile.
Speed test last week was still about 12 Meg so will be interesting to see if it is better now. May still be on reduced spectrum though I guess, Causing the slowness.
Haven't noticed any more coverage though. Took my children to the Cinema there on Saturday and still 3G in the city.
My friend has reported 4G twice and sent screen shots. (He's nowhere near the Plympton cell by the way. He's up near Derriford Hospital and when he had signal it was 4 bars or so). Was only turned on briefly though so they must have been testing.
Also I went to another company I deal with nearer home and a guy who works there just casually told me that he had enjoyed using 4G in Plymouth a few days earlier.
It has been on and off a few times.
