Selecting a Preferred GSM Carrier:
In some cases you may be prompted to select a carrier. When first entering a country with GSM service and turning your phone on, it will search for a network and after a short time, will display the networks that are available locally. Choosing the local Verizon Wireless preferred network ensures you the best carrier services possible.
