MVNOs have historically excelled at attracting customers—but struggled to keep them. Churn remains one of the most significant drains on profitability. Customers often jump ship for slightly cheaper deals, leaving MVNOs in a constant cycle of acquisition and loss. In the early growth phase, this wasn’t fatal, but in today’s saturated market, loyalty is everything. The mistake many MVNOs make is treating customers as disposable rather than building long-term trust. True sustainability comes from retention: rewards programs, value-added services, and customer-first digital experiences. Without loyalty, every gain is temporary. The honeymoon period is over because customers no longer commit—they browse, compare, and switch. MVNOs must break this cycle.
