I haven't had a mobile signal at home for the last 10 days and today I received a message saying I would get another update in 7 days if the problem hasn't been fixed before. There is a signal half a mile down the road which is frustrating.
I want to divert calls when there is no signal and there seems to be a code ** 21 * phone number # SEND which should do this. I'm probably missing something but can't work out where to send this code!
Can anyone point me in the right direction please?
My phone is a Xiaomi A2 Lite on the current Android version.
