If you have an older i Phone, you won’t see the update pop up. But i Phone 7 owners began complaining late last month and well into October about the device randomly dropping its LTE signal or showing a "No Service" icon when attempting to use Google Maps or Waze.

It's important to note that the only cell towers and cell sites that Sprint has been building since the Nextel merger have been relocation sites.So toggling the "Enable LTE" function to "Data Only" in the settings panel seemed to temporarily solve the issue, according to .There is also the possibility that the issue stems from a fundamental flaw with how the i Phone 7 using i OS 10 interacts with any CDMA-based network, which includes those of Verizon, Sprint, US Cellular and numerous other international carriers.
