Can’t send SMS to my sons phone!
Bit of background - my son has an iPhone 7, I have a iPhone 12. We are on family sharing and I use Screen Time to put restrictions on his phone - for specific apps only - and a downtime for screen time. He is on a data & calls plan and when he reaches around 100% he switches mobile data off and just uses wifi - because every percent over costs him money.
Now, all of a sudden I can’t SMS him at all when he doesn’t have acces to mobile data. I need to be able to reach him when his data is off and he doesn’t have wifi.
My husband can - iPhone 12 and my parents can - Android, it’s just me.
On both our phones we have iMessage, convert to SMS and MMS switched on. Send/Receive is on with each phone numbers ticked and they are in proper area code format. The messages eventually come through when he gets home and his wifi connects, or when he picks up wifi somewhere.
Why cant I reach him and everyone else can?? I’m at my wits end…
I’ve tried switching things on and off, restarting phones and sending a text using MMS to his iCloud ID email - still no.
can anyone help.
Thank you
iPhone 12, iOS 15
