I know how to identify the device model (STL100 - #) once the device is on but is there anyway to identify it by the numbers on the box?

I remember reading a thread about this, and unfortunately it isn't possible without checking the phone itself.

Edit: I guess the OP is talking about the STL100-# device number only. I meant the RFxxxxxx model number.

there should be the number on the box, and also under battery

Is there a.listing somewhere that shows what model can run on which US carrier?

RFG81UW "London": HSPA+ 850/900/1900/2100. Will work on AT&T's 3G/HSPA+ networks, and in some TMO markets that have 1900 MHz 3G/HSPA+. No LTE.

RFH121LW: LTE 800/900/1800/2600, HSPA+ 850/900/2100. Will not work on US networks.

RFK121LW "Lisbon": LTE 700/850/1700/1900, HSPA+ 800/850/1700/1900/2100: Will work on AT&T and TMO's 3G/HSPA+/LTE networks. Best model to have in North America.

RFF91LW: LTE 700/850/1700/1900 HSPA+ 800/850/1900/2100. Will work on AT&T and TMO LTE networks, and the same 3G/HSPA+ networks as the "London."

Great, thank you! Now where on the phone would you find the model numbers?

[Silverfern]

its under the battery, or on the box

[ralfyguy]

Thank you guys!

[raino]

its under the battery, or on the box

Both the STL100-# and RFxxxxx are on the box?

[Silverfern]

should be, at least for mine, the RFXXXXX should be printed, the STL100 should be in a sticker or something. you can determine which STL-100 it is by looking at the RF number
