Updating cell towers
This service is available at any time, day or night.
After your phone updates -- or if you have to do it manually -- you will enjoy a longer battery life with fewer dropped calls.
However, if your phone is 4G and has a SIM card, updating your roaming towers in this way can do more damage than good to your SIM card.
If you own a Verizon 4G device, the update of the nearest towers is an automatic process, and you do not need to take any action to keep your phone updated.

However, you can manually force an update if you feel the automatic process has failed.
Some signs that your phone needs to be updated are a larger number of dropped calls and a drain on your battery. Your phone will automatically update to the nearest towers.
