I’ve had them pestering to upgrade to 4G. They have phoned about 5 times, and always beginning with “We want to check you phone is displaying EE as the network provider…”. They then take you through security and start with the selling.
I last one to phone said he was checking the coverage when I lived, and confirmed I could, would I like to go ahead? I was sat at my computer and I know I haven’t got a hope in hell of getting 4G, so I got him to wait while I called up the coverage checker. It clearly shows I can’t get 4G. He started mumbling and then said his computer was restarting. He had basically blatantly lied to try to get a sale. What a scumbag. It’s a shame, as I want to upgrade, but as a point of principal, they can ram it.
