I’ve never had an iPhone.
All I do is make/take calls.
This one AT&T unit works just fine for me:

Was on a friend’s iphone plan for awhile.
They are quite smooth..and quite expensive,too.
Now i have a TracFone and pay $20/3 month. No data..no frills. More freedom :).
Use public wifi for maps,FR,weather and play a few people in Words W/Freinds.
Life is good.
