Sorry if I have not explained myself and am probably using incorrect terminology. When I joined EE a couple of years ago I bought an ee SIM card and a dongle. I put the SIM card into the dongle, which is only used at my caravan and is data only. Before I could connect any of my devices ie laptop,iPad, iPhone etc I had to go into the settings of each device and look at Wi-Fi, select the one that matched the info on the SIM card eg: 4GEE-Wi-Fi 4263-2.4GHz and then put in the password that came with the SIM card. Then my devices would connect. Fast forward 2 years. I have bought the Scancom EE SIM card, took the original sim out and put the Scancom one in. I have not needed to put in any sim details or a password. Every device is working! When I look ,in settings, on each device and look at what it is connecting to it still displays the old sim details. Now, the only thing I can think of, and you will tell by now I am far from expert, is that even though I have cancelled my old contract the 30 days you have to give is not up yet and so it has not actually been cancelled
