How to Set Up Two Phone Numbers on One Cell Phone

1. Create a Google account. Having a Google account allows you to request a Google Voice account. There is usually a waiting list before receiving a Google Voice phone number, but you must have a Google account before requesting a Google Voice phone number.
2. Set up Voice options. Once you receive your invitation to join Google Voice, you will need to decide what you want Google to do when your Voice number receives a call. Under the 'Settings' menu, you can add the phones to which you would like your Google Voice calls forwarded. Adding a cell phone to this list will enable Google Voice to send incoming Voice calls directly to your cell phone.
3. Set up your phone options. Google Voice has several options under the 'Settings' menu, including using Google as your voice mail. With this option, Google Voice will record all your voice messages, transcribe them and either email or text the transcript to your phone.
4. Share your Google Voice number. If you want to use one number for personal and the other for business, having a Google Voice number and your original cell number both ring your one cell phone allows you to keep business and personal calls separate. To set this feature up on your phone, make your Google number a contact in your phone. If possible, assign a special ring tone for your Google number contact. With some phones, you can also assign a caller ID picture that will appear whenever calls from a certain number reach your phone.
