Application integration and data migration

Our team has an extensive positive track record of implementing multiple Telco projects and developing a diverse range of large-scale Telecom applications. We have developed a new robust and flexible, all-in-one Rating, Billing and centralized Product Catalog system that has replaced a legacy billing system for a leading telco provider with 7 million subscribers.

Included into scopes of the delivered projects, we have migrated the entirety of data on customers, resources, Product Catalogs, and services, and seamlessly integrated the new solution with the client's legacy Telecom systems (Ordering, Mediation, Fulfillment, and others).

Our case studies

The present-day continuous evolvement of wireless networks, global 4G coverage, the advent of 5G technologies and IoT, as well as the emerging global internet coverage projects all make it necessary for Telco providers and software vendors to keep pace with this rapid evolution.

SYTOSS stays on the cutting edge of the Telecom software development technologies, and we are always eager to fulfill your software needs in this area knowledgeably and with premium quality.
