One Crna Gora

One Crna Gora is a Montenegro-based carrier headquartered in Podgorica and part of Hungary’s 4iG Group since December 2021. Its services combine prepaid and postpaid mobile plans with mobile internet, fixed connectivity, and digital tools for households and businesses. The company says it has operated in the local market for nearly three decades.

For individual customers, the catalog includes voice and data plans, top-ups, roaming, and eSIM. The Moj One app lets customers manage a line, check or activate services, and pay bills from a phone. Because plans and promotions change, the company’s website is the place to compare current terms before choosing a plan or device.

The business division adds connectivity and information technology solutions, including fixed internet, Microsoft 365, business messaging, fleet monitoring, and machine-to-machine services. The Biznis portal brings together account administration, expense tracking, and service management. Corporate customers have a dedicated contact channel separate from consumer support.

Customer service runs through contact centers, chat, digital channels, and retail locations. The 1700 line is available around the clock, and the company lists its corporate address on Džordža Vašingtona Boulevard. Its offering spans everyday communications and business systems, while coverage and terms depend on the customer’s address and chosen plan.
