Its very easy to get a us phone number for personal use, let me show you below;
Google Voice (https://voice.google.com) lets you choose a free U.S.-based phone number. You can then make and receive calls within the U.S. and Canada for free online or through an existing land-line or mobile phone, and send and receive text messages for free online or through the Android or iOS mobile clients.
Apart from free calls and text messages in the U.S. and Canada, you can also make inexpensive international calls.
In addition, you can call your own Google Voice number from a public phone or a friend’s phone, and after entering your PIN, you can listen to your voicemail and make calls using your Google Voice number. Another feature I like is that it automatically transcribes your voicemail messages using Google text-to-speech technology, and then sends them to you as a text message.
You can block individual callers, set up custom settings for groups of callers (for example, family members, friends, work associates, etc.), and screen calls before answering.
Just like with older physical answering machines, you can send a call to voicemail, listen as they begin to leave a message, and pick up the phone at any time. When you’re on a Google Voice call, you can record the entire call and have it transcribed automatically, and then listen to it and read the transcription on the Google Voice website.
There are other free VOIP services, and other free telephone services out there, but Google Voice is the one I’ve had the most positive experience with.
