Couldn't find the answer by searching.....I had a 7520 that was destroyed due to water damage....my friend gave me his old 7520 and I thought I could just pop in the SIM card and voila! no such luck....my address book will not save contacts...what am I doing wrong?
Your contacts are not saved on the SIM card. They are stored on the BlackBerry itself. Hopefully you did a backup using the Desktop Manager Backup/Restore facility so you can restore your BB to your newer 7520.
