If your phone isn't working with Twitter, the first step is making sure it's verified.

You generate your verification code when you add your phone to your settings page. If you refresh the page and the code is still there after sending it to Twitter, your phone is not verified. If verification is not successful, make sure your phone is compatible with Twitter. A simple test before contacting your provider is sending HELP to Twitter to see if you get a reply. If you do, your phone works!

For US, Canadian, and Indian residents: if you don't receive a reply from the HELP command, check with your provider to make sure that texting to short codes, particularly 40404, 21212, and/or 5566511, is enabled.

(Hint: send something like "weather, san francisco" to Google's short code, 46645, to see if your phone works with other short codes.)

Some phone companies don't support messaging to short codes. The following carriers are not supporting messaging to Twitter's short codes:

-Cellular One
-Metro PCS
-Cincinnati Bell
-Cricket

If you contact a provider that does not support Twitter that you don't see listed here, contact support@twitter.com and we'll trade you a t shirt for the heads up.

For international residents: if you don't receive a reply from the HELP command, check with your provider to make sure that you can send SMS messages to +44 762 4801423. If you do receive a reply from HELP but your phone is still not verified, there is most likely an error in the format of the phone number (such as a missing country code, extra zero, etc.) Try removing your number and re-adding to generate a new code, and send again.

If you've tried everything above and still can't verify your phone, send your Twitter username and associated email address with the following information to Twitter Support for investigation:

1. Country, city:
2. Mobile Number:
3. Mobile Provider/Carrier:
4. Date/Timestamp of last attempted message sent to Twitter (if you don't have one, send HELP and use the info from the latest message.)

For those who cannot use Twitter via SMS, you can use your mobile web browser to access m.twitter.com. Alternatively, try signing up for email updates with Twittermail.com, or use one of the many 3rd party applications listed here:
