CALLUP to Showcase at CommunicAsia New Version of the Company’s Remote Management System for SIM Cards

Rosh Haayin, Israel, May 15,
2017. CALLUP, a provider of Value Added Services (VAS) and Mobile Device
Management (MDM) solutions for the telecom industry, will showcase at
CommunicAsia 2017 (Singapore, May
23-25, 2017) an enhanced version
of SIM OTA, the company’s remote management system for SIM cards. The system
allows cellular operators to manage files and applets on subscribers’ SIM
cards. This enables remote life cycle management of the card from its
activation by a new user, through upgrades and updates, until the card is
canceled. SIM OTA has been installed by major cellular operators in Europe,
Latin America, Asia and Israel. The new version, SIM OTA 4.0, will be displayed
at CALLUP’s booth (the Israeli pavilion 1E2-01).

SIM OTA 4.0 supports
all standard files of the SIM card’s IP Multimedia Services Identity Module
(ISIM). In addition, the new version includes an advanced, new GUI-configurable
general OTA script that fits many cellular operators, for the activation and
swap of SIM cards. The product’s GUI has additional and improved
functionalities, with more options for SIM profile editing, card editing,
scenario and script editing and more. 

The required disk space for transaction log has been reduced and more secured
daily/weekly report subscription mechanisms have been added. The automatic report subscription system enables the operator’s executives
and technical professionals to subscribe to system reports and receive them
directly to their email.

Using SIM OTA, operators can create dynamic distribution lists based on various
criteria, such as file types and actual content. The distribution lists enable
the operators to update specific groups of cards according to the pre-defined
parameters. This feature has been improved in the new version and includes more
criteria.

“SIM OTA has become popular among mobile operators worldwide, saving them time
and money, while improving the service to customers who do not have to arrive
at service stations,” said Alon Roth, CALLUP’s CEO. “Our engineering and
technical experts developed creative solutions to address the needs and
challenges of mobile operators worldwide, and the new version is further
evidence of our commitment to excellence and technological innovation.”

SIM OTA is based on CALLUP’s MDM+ platform, used for mobile device management.
In addition to secured Remote File and Applet Management, SIM OTA includes advanced
features such as Steering of Roaming (making it possible to determine which
mobile operator will be automatically selected by the subscriber’s phone during
roaming, according to priorities based on agreements between the cellular
operators), Location Tracking and Welcome SMS (sending an SMS to subscribers on
joining a particular mobile operator while roaming). 

The SIM OTA platform includes support for 4G cards. It supports the LTE
standard and enables operators to send control commands to SIM cards using
applications programming interface (API). The system can remotely update any
file in the card’s file system that has permission for remote change, such as a
file used to identify the card, a file containing SMS parameters, a file
containing SMS parameters, network selection file and others.  

The system will automatically repeat the update process on SIM cards that could
not accept the original update due to various reasons, such as devices that
were turned off or subscribers who were in roaming.
