3G and 4G frequencies
I am travelling to Washington DC and New York from China.
My smartphone support:
Support HSDPA to 42Mbps
Support HSUPA to 5.76Mbps
Download DL: to 150Mbps Upload UL: to 50Mbps
Can I use my phone on the network of AT & T?
Especially the 3g and 4g network?
(Because my phone only support 1900MHz, not both 850Mhz & 1900MHz. I am very confused. )
Thank you very much.
