The family is changing carriers and all 3 lines will be on iPhone 5s. The older phones are of 2 types, a Samsung smartphone and 2 older Nokia non-smartphones. What is the best/easiest way to transfer contacts? With the current carrier, I have the option of downloading the contacts from our acct. website, in .csv or .vcf formats, and I have already done that. Will either of those read into the iPhone (maybe from desktop computer via bluetooth?) and establish a usable contacts list? Or is there a better way? The new carrier (Verizon) tells me they "may be able" to transfer the contacts if we bring the older phones to a store. But I would prefer to have another option available.
