Hello all,
I recently bought HTC U11 on craigslist and the seller told me that he has absolutely no problem using it on GSM networks. I searched for its IMEI number and it showed that the one I bought is 2PZC100 model. Will it work well with AT&T? imei.info website shows that it has the following LTE-FDD frequencies: 700, 800, 850, 900, 1800, 2100, 2600. Any help is appreciated.

Thanks.

The 2PZC100 is the international unlocked version. It should support 3 out of the 4 LTE bands AT&T uses (2, 4, 17):

Thank you very much. How much of a deal is that its missing three bands? Can I still get LTE mostly everywhere in USA with the 3 available bands? How do I know which band is deployed where? Thanks.

Actually, this information might be more current: https://forums.att.com/t5/Phone-Devi...8/td-p/5359265

Since the phone supports Bands 12 and 17, it shouldn't be an issue, since these are AT&T's backbone. The only band the phone is missing is 30, which doesn't seem very important in terms of coverage.

Thank you very much. Looks like the phone is also missing frequencies. Does it matter that its missing 2100, 1700, and 1900 frequencies?

Are you talking about for UMTS (3G)? I think all carriers in the US use only 850 and 1900 MHz for 3G, which the phone supports, so it's fine.

I was looking at device compatibility on frequencycheck website you shared in the first post. According to it, my device is missing LTE B2 (1900 PCS) and LTE B30 (2300 WCS). But it has LTE B4 (1700/2100 AWS 1) and LTE B17 (700 bc)

The Phonearena.com link I shared above says the device supports LTE band 2. It doesn't support band 30, but as I mentioned before, band 30 doesn't seem to be a very prominent one for AT&T. 12 or 17 are the mainstays for AT&T which the phone supports.
