[Q] Use Sim from a LTE AT&T S4 with international S4? - Galaxy S 4 Q&A, Help & Troubleshooting

I have the USA version AT&T galaxy S4 with an At&T sim...
also have the Octa core international Galaxy S4 on the way.
Wondering if one can swap the sim cards back and forth
without any sort of disruption?
Thanks so much.

if the Octa versions unlocked, yes you can swap but you will not get LTE speeds.

In theory, there shoult not be any problem. But what T-Mo are you talking about?
you want to use a TMo SIM, or want to know if you SIM will connect in roaming?
You did not provide a lot of details...
you can check frequencies here: http://en.wikipedia.org/wiki/List_of_LTE_networks
Also, you must have a LTE aware SIM.
Thanks,
just wanted to make sure that my phone can use LTE/4G offered by T-Mo USA because it is from Korea/China

Been thinking about replacing my Note 2 N7100. It does not work on ATT 4G LTE
Which unlocked international Note 4s are best for AT&T with regard to LTE Bands in the US. or do I have top buy the AT&T variant for reliable LTE?

But will they technically work in the US? I don;t want to pay $800 for a bootloader locked up Note 4. When I can buy an international version for the same money
