Hi MRFGUY,

R-UIM:
Overview:
The Removable User Identity Module (R-UIM) system solution contains user information and data features on a removable smart card about the size of a postage stamp. Once personal data is stored on the R-UIM, it can be removed and reinserted in a new device, transferring all the personal data to the new device without programming.

The R-UIM is a dual-mode solution that can store both GSM provisioning and CDMA provisioning on a single card. CDMA subscribers can insert the dual-mode R-UIM card into a GSM phone and instantly have all of their subscription data available in a GSM network. When used with a GSM handset, the R-UIM operates like a GSM 11.11 Subscriber Identity Module (SIM). For international travelers, the R-UIM allows roaming across CDMA and GSM networks with the same multimode terminal.

Benefits:

* Enables users to program personal information once and roam between CDMA and GSM networks with a multimode device
* Eliminates the need for consumers to program phones, PDAs and other wireless devices with the same personal information multiple times
* Provides operators with state-of-the-art security for applications like mobile banking and commerce

Key Functionality:

* IS-820 standard
* Support for all standard CDMA authentication protocols
* Storage capacities from 300 bytes to 32 kilobytes

cheers...
