OTP not received from bank , how to fixed

Also having this problem with NHS login. I need to reorder my prescription but can’t log on.

It has now been confirmed by NHS helpline that there was a network fault that caused this problem. It seems that service providers are either unaware of faults when queried or are unwilling to admit to them. In either case, the responsibility for solving the problems is thrown back at the customer with complex diagnostic tests and resets that risk losing various settings on the phone. I wish providers would take more care to investigate the cause of problems before assuming that the fault lies with the customer. There does seem to be a recurring issue with the connection between business messaging systems and phone provider networks (as was shown when Three failed to convey the government’s emergency signal test). No doubt there is a lot of finger-pointing going on which does nothing to help consumers.
