We can only send a text message to a mobile phone number (no Google voice or VOIP services). Supported carriers include Alltel, Appalachian Wireless, AT&T, Bluegrass Cellular, Boost Mobile, Cellcom, Cellular South, Centennial Wireless, Cincinnati Bell, GCI, Immix Wireless, Inland Cellular, IV Cellular, Nex-Tech Wireless, Nextel Communications, nTelos, Revol Wireless, Sprint PCS, T-Mobile, U.S. Cellular, United Wireless, Verizon Wireless, Virgin Mobile, and West Central Wireless. Additional carriers may or may not be supported.
If you have tried resending the message more than once and did not receive it, most often this is due to your mobile carrier not permitting us to send you a text message from our short-code (a special 5-digit number we use to send out SMS messages). Most wireless carriers allow their customers to block text messages from companies like ours, so this may be preventing our messages from getting through. Contact your mobile carrier to see if they are blocking the SMS message.
If you still need help confirming your phone number, feel free to contact us here at firstname.lastname@example.org and we can investigate why you did not receive a confirmation text message.
