My iPad will not send to a number that works on my iPhone ?
i text to a number several times a day on my iPhone 5. I can't get the latest iPad to text to this number which is an iPhone 4.
All my other contacts text fine on the iPad, just not this.
it isn't blocked in my iPhone messages.
howapple - hello
Is your iPad connected to your iPhone using continuity?
If not - then connect it
iPads cannot send SMS messages unless they are connected to a SMS capable iPhone - they can send iMessage over WiFi
