Why customers are leaving
Fiber and 5G home internet keep spreading into Xfinity markets. The day before Comcast reported, AT&T said it added a record 442,000 fiber and 327,000 fixed wireless internet connections in the same quarter. Comcast cited intense competition, aggressive fiber promotions in some markets, and more customers reaching the end of legacy promotional prices. Those factors increased churn during the quarter.
What it means for Xfinity customers
- Review your current terms. Comcast did not announce a change to existing Xfinity internet plans as part of these customer figures.
- Ask for a retention offer. Ask what you would pay after your current promotion ends and whether any retention offer is available.
- Compare first. If fiber or 5G home internet is at your address, get the price in writing before you switch, and check equipment return rules.
Xfinity vs. the main alternatives
