To update a Verizon phone, the star symbol followed by the number 228 should be dialed from a Verizon phone. When prompted, choose the second option, after which the phone will begin to update and the call will end. The actual update can take up to two minutes, but will not cost the caller any airtime minutes.
Verizon phones are equipped to update when the person who is using the phone changes location. The phone may change towers that the signal is drawn from, and the phone may begin to go into a roaming mode when it is too far from the home tower. Roaming can cost the user more money, but a phone that has not switched to a roaming mode may not be functioning properly. By updating the phone, the user will be able to get the best signal possible, whether it is roaming or within a home tower's range.
Users who are having trouble with the signal on their phone will often be asked to first update the phone to ensure that the problem is not coming from a poor signal. Once it has been updated for optimal service, a phone will work to its best capabilities.
