"Number not available. Which number would you like to send the message with?"
[quick background]
I have 2 phones. Which one has one SIM card. One is for personal and the other for work purposes.
Both devices are linked on my iCloud account and both with iMessage on.
The work number SIM card phone is always at home and my personal one is always with me. (I don't want to carry two devices everyday).
I was used to receive the messages on both devices and when I receive messages on my work number, it was always easy to reply the messages back.
But now suddenly when I try to reply messages from my work phone through my personal phone the pop-up shows up "Number not available. Which number would you like to send the message with?"
I didn't change anything in the settings and it was working great before.
I really don't want to carry two devices everywhere I go.
Does anyone know how to solve this problem?
Thanks in advance.
