HSDPA 850 / 900 / 2100 & CDMA; TD-SCDMA are supported. Will my phone work with Data and Calls?

Without Band 4, you will not get LTE data.

For an LTE-compatible phone configured with LTE network preference:

• Calls: The device must absolutely support the frequency HSPA 850 MHz or 1900 MHz
• Mobile data: The device must support the dual-frequency 1700/2100 MHz (also called AWS or band 4) or 700 MHz

For a phone that only allows 3G or HSPA preferred:

• Calls and / or mobile data: The phone must support the 1700/2100 MHz frequency (also called AWS)

Cheers :)

Will it work with 3G internet though?

Thanks!

It wont be reliable only one frequency supported!

I don't think it will work with 3G data either, since it doesn't have 1700/200 in 3G either.

Yep I agree with Allison!

You must have 1700 to be able to fully use your phone in this network.
