Updating cell phone towers
You can search for "Open Signal" in the i OS App Store directly or use the link below to jump right to it. Once you have Open Signal installed and open, you'll need to give it access to your location in the notification prompt.Open Signal uses your position to show you nearby cell towers.
The setting will likely be set to "Voice & Data." Cycle it to "Off," wait 30 seconds, and then cycle it back to the previous setting, either "Voice & Data" or "Data Only." Once your i Phone's LTE antenna reconnects, it will search out the antenna with the strongest signal and connect to it, likely a different one that you were initially having issues with.When a phone is connected to a cellular network, it continually checks the signal strength of nearby towers and communicates that information to the network.In theory, when a phone's connection to a cell tower drops below signal strength of a nearby one, the network should switch the phone to the new tower.The carrier updates are usually very small and make adjustments or improvements to carrier specific settings pertaining to the cell network, data, personal hotspot, voicemail, text messaging, or making calls.While you may see a carrier update pop up randomly on your i Phone, or a request to install one during a general i OS update, you can also manually check for these carrier updates on your own at any time.
