★☆☆☆☆Jason R. Patrick3/26/2026
You can‘t pay with credit card only through App store

That is totally unacceptable

★★★★★JayzSuperMac2/26/2026
Just like calling down the street

The call was clearer than some that I make to folks in country, let alone in the same city. Very pleased with the billing rate and quality of call I experienced calling Ireland.
