T-Mobile in USA is currently testing the 4G HSPA+ Service on iPhone. The news emerged yesterday when one user reported that he saw 3G connectivity on his iPhone near the Moscone West convention center where Apple is going to hold Worldwide Developers Conference next week.
Users of T-Mobile in USA are restricted to slow EDGE networks which are of no good in todays requirement. It was already known that T-Mobile will be offering the 3G connectivity for users in 2012 and the coverage roll-out be nationwide.
T-Mobile didn’t deny the news and stated a response as below
While upgrading coverage inside the West side of the Moscone Center, T-Mobile has also deployed 4G HSPA+ service in the 1900 MHz band to test the live network on a small scale.
As part of the company’s previously announced $4 billion network modernization effort, T-Mobile plans to launch 4G HSPA+ service in the 1900 MHz band in a large number of markets by the end of the year, which will make our 4G network compatible with a broader range of devices, including the iPhone.
T-Mobile doesn’t offer iPhone in the USA and is currently only one of the four major cellular operators who doesn’t it. This is due to the incompatible current frequency of the operator.
