I can’t receive messages from an iPhone

[Android Central Question]

I can send messages to my girlfriends iPhone and she receives them, we can both call each other. But, if she tries to text me back I never receive it and it doesn’t say delivered on her end. It’s a Samsung j7

Have you ever used this mobile number with an iPhone? If so, you may need to deregister from iMessage:

Also have her send you one message that has SMS checked.
