I got a new Iphone XR on January 5, 2019. I was able to text the two people for 3 days. I have not been able to text or contact them since January 7. I have contacted your tech department 3 times regarding this issue.The techs have had me reset my network settings and sync some other information but all that did not work. It has been a pain not able to resolve this problem. Please help me with this issue!!
