iPhone 5S - Modell A1530 vs A1457

Hi out there!

What about the difference between the two models in the headline? - If the A1457 is supported in my country, concerning LTE, does the A1530 also work, as it's got the sames LTE-bands and some extra bands?

Thanks for helping out! :-)

To make sure: I could buy it from Asia, but want to use it with LTE in Europe...

Thanks! :-)

Btw: Is there a difference between "TDD-LTE" and "normal" LTE ... ?
