Digi, the Romania-linked telecoms operator, is proceeding with a stock market listing while holding the top position in mobile number portability in its market, attracting more than 100,000 lines per month from rival providers. However, the company is beginning to feel competitive pressure as aggressive promotional offers from competitors have started to erode its own customer base. The debut marks a significant milestone for Digi's expansion ambitions, though sustaining its growth rate may prove challenging in an increasingly contested market.
