I'm switching my iPhone from T-Mobile to AT&T -- back-up advice?
I'm seeking back-up recommendations.
I'm switching my iPhone 6 cellular provider from T-Mobile to Consumer Cellular/AT&T.
I've already purchased a new Consumer Cellular/AT&T SIM card which is required by the new provider. Before I remove the current SIM card and while I'm still with T-Mobile, I want to make sure I'm backing up what's necessary. I've done iCloud backup of the text messages within my Messages app so I believe I'm okay there.
My big question is: How do I backup other Phone data, in particular, my Voicemail messages?
I discovered that I can air-drop Voicemail messages one-at-a-time to iTunes on my iMac, but that's a pretty tedious process. Is there a better way to do that?
Also, are there other back-up tasks which I should do? Any advice, links, or tutorials would be much appreciated.
Thanks very much.
