.....the forum members will be better able to assist you. If it has no SIM card slot, I suspect it is a Verizon, Sprint, or Alltel device (unless it is from an international carrier). If you can turn the phone on, you might be able to determine the model # from the settings icon on the phone. Good luck.
Thanks to those who have already provided me with some answers to previous questions.
I have three more questions. My wife has just acquired a Motorola Razr flip phone, V3, pink, used.
Question 1: The battery in the phone is bad, and will need to be replaced. What is the difference between the BR50 battery, and the BC50 battery. They look physically the same. eBay sites say that either will fit the V3 phone. (I have a good BC50 battery).
Question 2: How do we tell the model of the phone, i.e: V3i, V3e, V3m, etc? Can't find the designation on this phone. (The model might determine the battery number?)
Question 3: How do we know which carrier is used for this particular phone, Verizon or AT&T?
This phone does have a place for a sim (micro SD) card. Most sim cards I have found on-line also have an adapter with them. What's the adapter for?
