Why can't I activate 'call waiting' on my mobile?

The solution may be to set your mobile to 3G, activate 'call waiting', and then set the mobile back to 4G again.

'Call waiting' allows you to switch between two calls if someone calls you while you're already on the phone.

If you need to use this function on your mobile, it's important that you activate it both on Myfone.dk and on your mobile phone.

On some phones, it's not possible to activate 'call waiting' on 4G. Instead, you need to set the mobile to 3G before you can activate it. Once you've done that, you can set the mobile back to 4G, and 'call waiting' will still work.
