People often want to send text messages to friends and family without their number showing up on the acquaintance's phone, but it's not always obvious how to accomplish this task. There are a number of websites and applications that can help.
From the Web
Text messages can be sent anonymously and for free by downloading an app or using a website, as long as you know the mobile phone provider of the person you are trying to text. For example, if your friend uses 02, you could visit AnonTxt.com, choose 02 as the provider and send a text message. You can leave the "from" field empty to make it anonymous!
Free anonymous text websites
Some free text messaging websites allow for anonymous texts to be sent. Examples include Pinger, TextPlus and TextNow. These websites allow you to send text messages to any mobile phone without displaying your mobile phone number.
Send anonymous texts from your iPhone
If you have an iPhone, you can send anonymous text messages from your mobile phone using an iPhone application. One application that allows users to send messages anonymously is SMSveil. After purchasing this application, iPhone users can send unlimited anonymous text messages.
