I a very unhappy T Mobile customer, I have had terrible reception issues with the 5S in various US cities, mainly Las Vegas and northern NJ. T Mobile has tried everything, new sim card, new iphone, and I still have dropped calls, outbound call failed with 3 bars of 4G 5 times in a row. The reception bounces back and forth from 4G-Edge-no service. 2-3 bars of LTE, it still drops calls. Other threads indicate I'm not alone with this issue. I'm ready to get the Samsung Galaxy 4 and get rid of the iPhone as I use this for work and this is far from acceptable.
Will this new 15.6 improve the reception with this phone on your network?
