rome and have a live umi USA stock in my company's T-Mobile, the phone works but does not connect to the 4G LTE network. What can I do to solve this problem.??????
The USA T-Mobile uses 700/1700/1900 MHz LTE frequencies but UMI Rome supports only 800/1800/2600 MHz. So, unfortunately you'll never be able to connect to a 4G network in America.
