You sometimes can type the phone number into a computational search engine (e. g. , WolframAlpha) to bring up information about the carrier. If you don’t know which of these five carriers the phone uses, you’ll need to send a message to all five of them.

If you don’t have such an email, you’ll first need to create a new email address for the purposes of texting without showing a number. You can also use an anonymous email service.

Some phones will block automatically any text received from an email address.

If you don’t want to use your own email address, you can use an anonymous email service, or you can create a new Gmail account for free.

The text message will contain your IP address. If you are concerned about your privacy, you may want to use a VPN.

Open the Google Play Store (Android) or the App Store (iPhone). Tap the Search tab (iPhone only). Enter “TextNow” in the search bar. Tap TextNow in the search results Tap Install or GET.

On Android, you’ll instead tap the pencil-shaped icon in the lower-right side of the screen.

On Android, tap the blue paper plane-shaped icon instead of Send. After sending the text, you may be prompted to add contacts or enable notifications if you haven’t already done so.
