I love my Blackberry Keyone and want to stay with it, but I have just discovered that exactly the same SIM is massively slower in the Keyone than in the P20.
I ran a speed test in identical conditions (sat in same chair, five minutes apart) and the P20 had an average top speed of 26 meg download whereas the Blackberry Keyone was 10 meg download.
Any thoughts would be much appreciated.
