I live in San Francisco but work in Pleasanton. I noticed Sprint's LTE has been turned on in some areas (possibly for testing). Anyways, for those interested here's recent results from Pleasanton, CA:
So I had my battery out of my phone for something last night and I noticed that my Sprint S4 has a sim card. None of my previous other Sprint phones had a sim card. I'm guessing this is for the 4G LTE? Does the Sprint S4 have CDMA and GSM radios in it?
According to Sprint’s Chief Executive Officer Dan Hesse, the company has reached a milestone of over 1 million LTE devices sold. Sprint offers some great LTE devices such as the Samsung Galaxy S III and HTC EVO 4G LTE.
