Why am I unable to receive my fathers text messages from his iPhone?

AC Question

Samsung/Iphone

I have been having problems where I don't receive my dad's texts and he has a Iphone 6 and I have a samsung Galaxy j5. But it has been doing it for at least 3 of my old phones too : this one, an LG and a Motorola. We are trying to find the problem but don't get why it doesn't work cause we checked everything and no one blocked anything but it steel doesn't work.

PS : My dad has a english sim card and I have a french sim card.
