can I travel to Europe and buy a SIM from a local carrier and use that in my Nokia Lumia 1520 phone?

[WPCentral Question]

Hello from a non tech savvy girl,
I am currently in the US and looking to purchase the Lumia 1520. I see that there are unlocked gsm AT&T phones (I currently am using at&t go phone no contract plan) and international versions of the phone.

I found a phone for sale that says this in the specs:

Cellular Band: LTE 700 / 850 / 1700 / 1900 / 2600
GSM 850 / 900 / 1800 / 1900
WCDMA 850 / 900 / 1900 / 2100

I am wanting to be able to use it both here in the US on AT&T gophone no contract plan and in Europe/other parts of the world with a local sim.
Will that be possible?

Gratitude~

According to https://en.wikipedia.org/wiki/AT&T_Mobility this phone should work on AT&T with 4G LTE. Basically, it should work with any wireless operator that uses these frequencies for their network. Check on their website for the details.
