Remote Management System for eSIMs for Both Smartphones and IoT Devices
Rosh Haayin, Israel, July 12, 2017. CALLUP, a provider of Value Added
Services (VAS) and Mobile Device Management (MDM) solutions for the telecom
industry, today announced eSIM OTA, a remote management system for eSIMs
(embedded SIMs) for both smartphones and IoT (Internet of Things) devices. eSIM
OTA is an enhancement of CALLUP’s SIM OTA, the company’s existing remote
management system for removable SIM cards. SIM OTA has been installed by major
cellular operators in Europe, Latin America, Asia and Israel.
eSIM OTA allows cellular operators to upload their SIM profile and to issue
control commands to supporting devices and eSIMs embedded in smartphones
and IoT devices. This enables remote life cycle management of the eSIM from its
activation by a new user, through upgrades and updates, until the eSIM is
“So far, eSIMs have been used mainly in IoT devices, but today smartphone
manufacturers are starting to replace the traditional SIM cards in some models
of smartphones with eSIMs. It is expected that in the coming years more and
more smartphone models will use eSIMs,” said Alon Roth, CALLUP’s CEO. “The new
eSIM OTA system reflects our commitment to innovation, enabling mobile
operators to implement up-to-date technologies. In addition to eSIM OTA, we
will continue to provide our existing SIM OTA system, to enable mobile
operators to manage all the removable SIM cards used by their subscribers.”
All the features of CALLUP’s IoT Engine are also included in eSIM OTA, and can
remotely manage the entire life cycle of eSIMs embedded not only in
smartphones, but also in various devices, such as smart meters, home
appliances, in-vehicle systems and personal devices.
eSIM OTA supports the GSMA standard for subscription management, and
all standard files of the eSIM IP Multimedia Services Identity Module (ISIM).
In addition, it includes an advanced GUI-configurable general OTA script
that fits many cellular operators, for the activation and swap of eSIMs. The
product’s GUI includes a variety of functionalities, such as eSIM profile
editing, card editing, scenario and script editing and more.
eSIM OTA’s automatic report subscription system enables the operator’s
executives and technical professionals to subscribe to system reports and
receive them directly to their email.
Like SIM OTA, eSIM OTA is also based on CALLUP’s MDM+ platform, used for mobile
device management. In addition to secured Remote File and Applet Management,
eSIM 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
The system will automatically repeat the update process on eSIMs 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.
