With a free USA virtual mobile number, you have the power to receive SMS verification codes and call at all times from anywhere in the world. No matter whether you are settled abroad, travel often or work remotely, you can always enjoy your virtual presence in the United States.

Google Voice changed that by actually taking over your phone’s calls and texts and making them smarter, but it requires you to have a U.S. number.

Twilio is an open PaaS platform for cloud services. It’s turned voice calls and SMS messages into an API that you can easily integrate with another app. Although Twilio is aiming at developers, for us who aren’t developers—especially those who live abroad. It’s an easy way to get a phone number in dozens of countries, make calls on the cheap to almost anywhere, automate text messages

Since Twilio provides free trial money for trial accounts to buy U.S. phone numbers, we can use Twilio to call and SMS messages, especially receive verification SMS online.

Creating a new Twilio account will get a $15.50 trial credit, which can be used to buy a U.S. phone number to receive and send text messages. Twilio will deduct a US number monthly fee of $1 and a fee for sending and receiving text messages from the trial fee.

Basically, numbers cost $1/month. Trial money can be used for 1 year.

If you need to keep the number later, you need to add credit to Twilio, with a minimum deposit of $20 from PayPal.

First, sign up for your free Twilio trial account. The signup process includes verifying your personal phone number: this is a security measure that is mandatory before you can try Twilio. If you upgrade to a paid user, you will not have this restriction on the need to verify before sending text messages.

For example, here I got the number 216-508-7135. Click choose this number if you like it. If you don’t like it, click Cancel. Then go back to the previous step and click Get a Trial Number to get a new number.

Of course, you can also choose other numbers outside the United States. Click the image below to search for a different number to get other country numbers.

The monthly fee for other country numbers is 1 to 15 US dollars. The key is that the free trial fee cannot be used to pay for the number of countries outside the United States.

If you don’t use your phone number for more than 30 days, Twillio will remove it from your trial project. If you decide to return, you can always pick a new phone number.

3. How to release a Twilio phone number

Twilio only allow one Twilio phone number per trial project. If you select a number or choose your own and decide that you’d like a different phone number, you must first release your current number, then pick a new number from the Buy a Number page.

To release your current Twilio phone number:

  • Go to the Manage Numbers page.
  • Click on the number you would like to release.
  • Click on the link at the bottom of the screen that reads Release this Number:

4. Check whether the number is a mobile number

US phone numbers are divided into mobile phone numbers and fixed numbers, both of which are 10 digits in format. We can use the freecarrierlookup.com website to find out if a US number is mobile or fixed. Query the Twillio number, it can be seen that is wireless is y, indicating that it is the mobile phone number. Number Carrier: Twilio/Inteliquent (SMS-Sybase) (MMS-SVR)

5. Inquiry number fraud score

I use the US number lookup tool realphonevalidation.com to look up Twillio’s fraud score (the higher the score, the lower the quality of the number). The Twillio number here scored 645 points, same as Knowroaming, Piranha Mobile, not high quality.

You cannot send SMS messages from your personal phone number with Twilio, whether on a paid or a trial plan. You can always send messages from Twilio numbers.

Sending from a Twilio number to a US number requires registration of brand and advertising information, so there is no registered brand information, so even if the sending to a US number is successful, the SMS cannot be received.

In addition, when the recipient’s number is added to China or the United Kingdom, the text message cannot be sent successfully. The reason is that sending to this area is not supported for free users

8. Elastic SIP Trunking

When you sign up for Twilio, you will get a free telephone number and a free trunk. You can fully configure this SIP Trunk for testing and placing actual calls to and from your business. Twilio Trial accounts can take full advantage of SIP Trunking services for testing, there are a few restrictions that apply only to trial accounts. Keep these in mind as you develop:

Trial Accounts have a maximum of:

  • 1 unique SIP trunk
  • 1 origination phone number
  • 1 Trunking termination call per second (CPS)
  • 4 concurrent calls

9. Trial Account restrictions and limitations

The processes for sending messages, making phone calls, and setting up an Elastic SIP Trunk are the same for a trial account as a full paid account. However, there are some restrictions and limitations imposed while you are in trial mode.
If your Twilio needs to expand, or you need to accomplish something that isn’t available to your trial account, you’ll need to upgrade your trial account to a full paid account. All you need to do to upgrade is provide payment information — your credit card details or Paypal account — on the billing page.

Twilio’s 1-year free US number to receive text messages is a great resource.
