Any Issues With Using Unlocked Telstra (Australia) Phone on AT&T MVNO in US?

[PianoJazz]

I bought an unlocked white Lumia 920 through Best Buy's website. I'm running on an AT&T MVNO (Pure TalkUSA). I was surprised to see that the phone was from Telstra in Australia. (There's no branding on the face of the phone, but part of the bootup sequence includes a screen with a big "T"; and some documentation in the box and About Phone confirm that it was originally meant for Telstra.)

Am I going to have any issues with this? So far there have been two problems:

1. I had to switch the region from the US to Australia to get a Nokia app update to download and install (Extras + Info, or Care, I think). (I then switched back to US.)
2. I cannot send MMS messages, nor do I receive the attached file of an incoming MMS message. Instead I get the "Get media content now" link, which does nothing. It seems this is a widespread problem, so I'll need to read up on it.

The only other thing is that the phone uses Australian spellings (e.g. "favourites"), even after I switched to US English. This doesn't bother me, but I was surprised the spelling didn't change to match the language change.

I just received this phone last week, so I still have time to return it and try again. Should I? What's everyone's experience with something similar to this?

Thanks.

For the MMS, you can try the Nokia Access Point app. That has helped people get the proper APN when they are using unlocked devices.

Thank you. Turns out, I already did have Nokia Access Point. MMS is now working. I deleted the APN entry I was using and started over.

As to using in the US a phone originally intended for Australia, are there any other concerns I should be aware of?

Thanks.

No they all the same . If you too concerned flash AT&T rom cheers,

Thanks, desitunez. I'll try to be a little more relaxed about this. I'm brand new to the Windows Phone world, in case that wasn't arleady obvious.

In the Android world I'm very proficient at installing new ROMs and kernels. So, if I were to flash a different ROM on the Lumia 920, I'm sure I could handle it. How would I get started? That is, where are the ROMs available? and is there one for an international version of a phone? (I thought that's what I was getting.)

Thanks.

If you have LTE access then try to do a speed test to make sure you're getting the full speeds. Our Aussie networks might work on different bands, although most phones here are quad-band anyway.

Good advice, schludadub. Thanks!
