By the end of 2025, AT&T had successfully extended its fiber footprint to cover over 70% of the city, enabling symmetrical upload and download speeds reaching up to 5 Gbps for a significant portion of residents.

In 2026, budget-conscious consumers in Corona Del Mar have several compelling options, with T-Mobile 5G Home Internet emerging as a leading contender for affordability. Its flat monthly rate of $50, inclusive of taxes and fees, offers significant value for its speed tier, especially when compared to traditional cable or DSL plans. This pricing strategy is a direct result of T-Mobile’s aggressive market penetration goals for its home internet service.

Spectrum also provides a competitive entry-level plan at $49.99 per month, which, while offering slightly lower speeds than some premium tiers, is notable for its lack of a long-term contract, a trend that providers are increasingly adopting in 2026 to attract and retain customers amidst fierce competition. While AT&T’s DSL plans can be economical, their speeds are significantly lower than those offered by 5G Home Internet or cable, making them a less attractive option for most users in 2026.
