Knocked Three on the head now, too unreliable from Feb onwards.
Interesting, I wonder if the improved performance meant some people in your area used it a lot more. Three suffered years ago with overuse from their original "unlimited" price plan, the One Plan, and eventually had to force people off it.
Now all the networks offer an unlimited plan, they shouldn't have all the "download the internet" brigade flocking to Three, but maybe its price dependent.
Doubt it, got a text saying the network is being improved, then later that day and the next day another to say network issues. From that day onwards the service was a joke, and to put the cherry on the cake it prevented me from getting CA across band 20 & 3 from then as presumably my two local masts has different equipment was now not compatible. Just to confirm on day 3 they sent a text saying your network has been improved blah blah blah, nope, you’ve just made it worse.
