Xfinity, Quantum Fiber, and T-Mobile are the best internet service providers in Boulder, Colorado. Xfinity’s coverage ranges across the entire People’s Republic of Boulder, and its superfast cable internet plans are a great option for medium-large households with lots of devices. But if you’re a Qualcomm or IBM worker with a home office, then you’ll probably want to upgrade to CenturyLink-owned Quantum Fiber, which offers unmatched performance in areas like Old North Boulder and South Boulder. Meanwhile, CU Boulder students on the Hill and other budget-conscious customers should check out T-Mobile 5G Home Internet.
