A working phone number is necessary if a website or app you sign up for needs to verify your identity via text message. You don’t need any of these apps if your phone can already receive messages. Still, they’re a must-have if sharing your primary number is a privacy concern, or if you have a tablet or other device that doesn’t support texting.
Free SMS Verification Text Phone Number | No Phone Number Required
TextNow is one of the most popular texting apps, with over 100 million users. It offers two services: one replaces your existing mobile provider (you get a SIM card) and the other is a second phone number for calls and texts. The second option is what you want, because that's all you need to do to receive verification codes.
Your new phone number can be in your local area code, or choose a different number. Signing up is easy because you can use your existing Google or Facebook account.
The app lets you choose a background for conversations, enable timestamps, set a passcode, export conversations, set a ringtone for each recipient, and add a shortcut to a conversation on the home screen. Since phone calls are also supported, you can set up your own voicemail if you want to receive calls in addition to text messages.
