I set Up new iPhone 14 Pro, but cannot call or text
My old iphone SE 2020 is still working and I am able to call using it. I backed up its data to the cloud, and transferred it to my new iphone 14 pro (I think, actually, it transferred via Quick Start). So I can check Twitter and use apps on the new phone, but I cannot use the new phone to make phone calls or send texts. What is my next step? If anyone can link me to a step-by-step guide, I would be grateful. P.S. My plan is to reset my iphone SE 2020 to factory settings and give it to my husband so he can replace his Android.... Thanks!
