Summarize the following:
Most carriers support call forwarding, but many impose a fee or require a one-time payment for activation. The easiest way to find out information about call forwarding is by calling your carrier directly. If call forwarding is disabled for your home phone, ask your carrier to enable it for you. Again, you may need to pay a fee or agree to a charge-per-minute rate before you can activate call forwarding. Most manuals have a section on call forwarding. Since home phones' settings vary more widely than the average smartphone, you should be aware of how your specific home phone operates in case there's an extra step or process that you have to complete before activating call forwarding. You can usually find a copy of the instruction manual on the phone manufacturer's website.
Check your carrier's policy on call forwarding. Activate call forwarding if necessary. Read your home phone's instruction manual.
