Unlock a phone

Many cell phone users remain confused on what it means to unlock a phone. Most commonly, this term is used to describe the process of removing restrictions placed on using a GSM cell phone by the manufacturer.

Bluetooth devices, wireless networks, and television signals also use this frequency band.

Unlocking can be done on GSM-based Treo phones such as the 650, 680, and 750. Unlocking does not apply to CDMA-based Treo phones such as the 700w.

Last edited by . Total of 11 comments in the discussion.

Cell phone cloning refers to the act of copying the identity of one mobile telephone to another. This is usually done to make fraudulent telephone calls. The bill for the calls go to the legitimate subscriber. This made cloning very popular in areas with large immigrant populations, where the cost to “call home” was very steep.

Cell phone cloning started with Motorola “bag” phones and reached its peak in the mid 90’s Read More
