lost numbers

[Rob Petrie E395]

If you have Verizon (Not sure about other brands) your phone is backed up to thier system every night at midnight. Its called Backup Assistant. Its usually done automatically when they set up the phone. If so all you have to do is take your phone to the store and they can put it back to where it was before the data loss (does not matter if you have a sim card or not).
Hope this helps.
