Hi. Have tried to sign into my NS&I account but unable to because I need to use the # key to enable authorisation & it isn’t being recognised. Advisors at NS&I have informed me this is a common problem on iPhones & the cause is the “DTMS files”? on the network. Have now been locked out of my account - very annoyed!! Can you enlighten me? Thankyou

Dual tone multi frequency (DTMF) is a technology used with touch tone phones, best known to users as the sound made when pressing a number key. It signals the phone company that you want to make a call and sends a command to the switch.

If not working it's gonna be a phone fault.

Try rebooting phone, clearing cache from the dialer app or call from a landline.

#Key working on my O2 Android. Can't see it being an O2 problem with the network

This is not O2 and we are all customers here similar to yourself and cannot answer account type queries.

Could be an hidden iPhone 'feature' 😉
