Will The Network Automatically Update The Time On My SGH-A637 Phone?
Yes, the phone uses NITZ (Network Initiated Time Zone) integrated into the handset's software and will automatically update, if enabled, the time and date while inside the AT&T digital network. If you roam outside of the AT&T Service Area, or turn on the phone in an analog roaming area, you will need to set the time manually.
To change the automatic update settings follow the steps below:
Tip: Automatic updates of time and date do not change the time you have set for alarm settings or calendar memos
Note: Changes may not take effect until the handset is power cycled (turned off then turned on again)
