Ester Solutions develop and supply vendor independent open standards platforms and software for SIM cards, including SIM applets and applications for SIM files access and management at Points of Sale. Founded in 2005 by Russian experts in SIM technologies, Ester Solutions proposes mobile operators systems and services, heavily adapted to Customers’ requirements and needs. We updated over 8,0 millions different SIM-cards "over-the-air" by means of "ESSO OTA": from loading SIM applet "Roaming Management" to SPN update, SMSC number change, PLMN and FPLMN files update etc. Working with the largest mobile operators in East Europe, such as Mobile TeleSystems, Vympelcom and Megafon, Ester Solutions developed and supplied variety of high class platforms such as "ESSO OTA", "ESSO Personal SIM", "RAMSN", as well as SIM cards applications "Roaming Management", "ESSO Personal SIM", "ESSO SIMbackup", all of which have registered rights of Ester Solutions in Russian Patent Authority.

Ester Solutions developed and successfully launched world unique, ÎÒÀ independent platform "RAMSN" (Remote Application Management Service Node) that enables Operator with unprecedented capacity to reuse memory of SIM cards on field. In response to end-user request, in mass campaign mode or in the Operator’s Point of Sale RAMSN enables load and delete heavy size SIM applets. Integrated with already existing OTA or supplied with ESSO OTA, RAMSN ensures successful individual and mass SIM applets download on millions of SIM cards. Already today, having sent empty SMS to the short number 000222, any Megafon Moscow subscriber may load or delete high scale SIM applets, such as HomeZone (Domashnya Zona) and Interactive Cellbroadcast (Kalejdoscope). Due to its "PosTool" client, designed for operations through PC and card readers, RAMSN allows Operators ordering SIM cards without SIM applets, leaving choice of service select (SIM applet) to the end-user. Either applet available in RAMSN system can be loaded onto new SIM card in the point of SIM card sale using Internet connection between PC with installed POStool and RAMSN in few minutes. RAMSN platform supports proprietary security algorithms used as protection for secure applet load. For instance, RAMSN supports DAP-algorithms and relevant DAP-keys created by Oberthur. RAMSN PC-based simulator named "Object Verification Simulation Tool" allows SIM vendors and independent applets developers perform complacency tests in their laboratories, required to check applet loads on different SIM-cards profiles. The outcome of OVST job is creation of universal files describing profiles, commands and applets, which Operator load into RAMSN. OVST usage experience has already been acquired by world known SIM vendors including Oberthur, Giesicke & Devrient, Sagem-Orga, as well as local vendors such as Sitronics Smart Technologies.

Company growth

Company future grounds on delivering already successful solutions to the new customers and markets, developing new platforms, active partnership with leading world system integrators, SIM client solution providers, SIM vendors and mobile handset applications developers.

Supported standards

Our software is based on Java and C++ technologies deploying open standards such as 3GPP, ETSI, Global Platform, OpenMobile Alliance. We extensively use Jboss as environment for ESSO OTA, Oracle TimesTen for replication redundancy in solutions with multimillions database and MySQL Cluster for smaller accounts thus providing flexibility in 3^rd party SW costs. Standard server hardware we use is SUN T2000.

Partners solutions

The main role also plays promotion, integration and after-sale maintenance of partners solutions devoted to mobile operators and mobile retail chains.
