Whether you are pulling a practical joke or trying to keep something a surprise, your phone number always gives you away. But luckily, there are a couple of techniques to send texts with a different phone number. Keeping your number a mystery can both add excitement and humor to an otherwise ordinary text.
Get a Google Voice number. Google Voice allows you to choose a local number that can tie all your different numbers, such as landline and cell phones, together. You can text from your computer or from your phone if your carrier has a Google Voice app. The number that appears as the return number will be your Google Voice number. A Google Voice number is free and only requires a Google account.
Send a text from the recipient's cell phone provider websites. Some phone carrier websites like, Verizon and Cricket, allow you to send a text message to one of their subscribers from their website. If you don't know their cell phone provider, you can search the number on the carrier's website or run a search with a reverse number directory, like 411.com (see Resources). Sending a text from the carrier's website requires a valid phone number, so make sure the number you use actually exists.
Mask your number. Many novelty websites, like Fake Message and Spooftel (see Resources), exist where you can change or "spoof" your number. These websites charge either a membership fee or require a purchase of credits to send a message, and some of the sites have released iPhone apps for greater accessibility. As of September 2010, Fake Message allows for a single free text in its trial membership.
