It’s easy to find the SMS address for most providers, but NET 10 seems to be a little different. Because Net10 service is provided over several different networks, in order to send an email text message, you first have to find out which network the recipient’s phone uses.
For example, a NET10 prepaid phone using the AT&T network would use the following format to send an email/text:
email@example.com (please be sure to substitute the correct area code and phone number).
However, if you find that the above doesn’t work, then maybe the Net10 recipient isn’t on the AT&T network. To find out which network the recipient is on, go to the Mobile Carrier White Pages Lookup and in the “Select a Carrier” option click “Other.”
Once you’ve selected “Other,” insert the area code and number for the NET10 user, click “Find” and the website will display the proper network SMS address under the “In Network” section. Now all you have to do is send the email (make sure to keep it short because SMS can only accept 160 characters).
UPDATE: Since writing this post, the carrier lookup option mentioned above is no longer free. They’re now charging $2.99 per month for unlimited lookups or $1.99 per lookup. Try using Telcodata or FoneFinder instead. They’re still free.
