Workz also offers a range of SIM based applications such as:
This application allows subscribers to hold two or more subscriptions (and two or more numbers) on a single one SIM Card. In the instance where a subscriber has two separate numbers; e.g. one for personal use and one for business use, they can operate both numbers from the same SIM Card. The Multi-IMSI also allows prepaid/postpaid swapping features on a single SIM card.
The IMEI Tracker app enables network operators to push device configuration settings such as APN, MMS and WAP to handsets immediately meaning customers can enjoy services without having to make calls to the operator or go through complex settings menus.
As currently most 2G SIM cards support up to 254 ADN (Abbreviated Dialling Number) entries, this limits the number of contact numbers that can be stored inside the SIM card. Extended Phonebook allows the subscriber to store more than 254 contacts on the SIM card through an easy to use menu structure and several features like SMS, call etc.
Password Manager is a secure password management application embedded in the SIM that can help subscribers securely store confidential information such as passwords and PINs. Using the most secure encryption algorithms the user can securely store credit card information, bank routing numbers and other data on the SIM card. The in-built security features in the SIM help protect the data stored which can only be accessed via a master PIN.
This application notifies the MVNO when the subscriber is roaming on another network.
