I have not been able to make a call using Siri since I got my iPhone 5s. I have tried tinkering with the settings but the problem still persists. The error message is I can’t call X using that number. Helpful tips and suggestions are appreciated
Your problem may be this:1.if your using iCloud, tap settings > iCloud and toggle on Contacts if it is off.
if this does not solve your problem, tap settings > general > Siri and turn Siri off then back on.
Also make sure that Settings > General > Siri > My Info where your contact is selected.
