This is normally transmitted by the network, but can be overidden to display a different tag. This is done by creating a tag for a personal/residential zone in the phone, and setting this zone to have the same settings as your normal carrier. So when the phone identifies the network system it believes it is in the personal/residential zone and displays the tag you have programmed. 1) Enter programming mode of the phone by keying *3001#12345# 2) Find out the ID of your operator by entering the NAM1 menu. Note the Home System ID setting. (16387 on Rogers AT&T in Calgary) 3) Scroll to and enter PSID/RSID lists (menu 7) 4) Select P/RSID 1 5) Scroll to PSID/RSID and change the setting to 1 6) Scroll to Connected system ID and change the setting to the ID of your system (eg 16387) 7) Scroll to Alpha Tag and enter the message you would like displayed. Scroll to Operator code (SOC) and enter coed for your provider such as 2050 for Rogers or 2049 for AT&T 9) Scroll to Country code and enter 302 for Rogers or 310 for AT&T 10) Power cycle your phone and hopefully your message will be displayed Note: This has only been tested in Calgary on the Rogers AT&T network so may not work on other networks. *3001#12345# Programming Menu: NAMs, Fieldtest, Serial Number, P/RSIDs *#639# Program Phone Number *#92772689# Warranty Information, Serial Number, Life Timer, Build Date, Programmed Date (editable once only) *#9999# Display Software Version Known Versions v 06.08 , 22/06/00 NSW-4 v 06.09 , 07/07/00 NSW-4 Nokia 8820 / 8860 *3001#12345# gives access to NAM1 and 2, sw version, security, alpha tags and heaps of other stuff.
