Phone and Home Internet in the United States: Compare Plans Before You Sign
A low advertised monthly price does not answer every question about a phone or home-internet plan. Before signing up, check whether your device works on the network, what the plan includes, and what you will pay when an introductory price ends. The Federal Communications Commission (FCC) provides tools for comparing offers and checking bills.
1. An unlocked phone is not always compatible
The FCC distinguishes unlocking from technical compatibility. Unlocking removes software restrictions that tie a phone to a provider, but it does not guarantee that the device supports another network’s technology or frequencies. Locking can affect physical SIM cards and eSIMs. Before buying a phone or activating a plan, ask the provider whether your particular device is compatible and whether it is locked.

2. Compare prepaid and postpaid terms
According to the FCC, prepaid plans charge before service is provided and typically do not require a credit check. Postpaid plans bill after service and often require a credit check for a new account; they may include a contract and an early-termination fee. A discounted phone may remain locked while installments or other conditions apply. Read the provider’s current unlocking and device-financing terms rather than assuming that every company follows the same schedule.

3. Read the broadband label
The FCC’s broadband-label page says providers of standalone fixed and mobile broadband plans must display labels at points of sale, online and in stores. Look for the price, introductory rate, data allowance and speed information, and the links to privacy and network-management policies. The page notes that the FCC approved changes to label rules in July 2026; use the label displayed with the current offer rather than relying on an old sample. Keep the offer and contract so you can compare them with your bill.

4. Check the bill and question unknown charges
The FCC advises checking whether you recognize every company and service on the bill and whether charges match the offer. Ask about data limits, roaming and international-call charges before using them. If a charge is unclear, ask the company to explain it; if it is incorrect, request its removal. If the provider does not settle the problem, the FCC’s consumer guidance explains complaint options. Bills in another language are not guaranteed: ask your provider whether your preferred language is available.
