Text messaging (SMS) is a two-way mobile messaging service. You can use your phone to send and receive short text and email messages. Text messaging allows you to send messages to T-Mobile and non-T-Mobile customers who have text-capable devices.
You can send messages to any email address. You can also have email sent to your device via text message. Each mobile number has its own email address in this format: firstname.lastname@example.org
Messages are limited to 160 characters. If a message exceeds 160 characters, it's automatically converted to a picture message (MMS).
T-Mobile doesn't keep copies of text messages, and we can't retrieve deleted or missed text messages. Some email services allow for text messages to be forwarded to your email, so check with your email provider to see if this is a service they offer.
Some plans include a monthly allotment of messages (text, picture, video, and IM). If messages aren’t included in your plan, you can find messaging rates by logging into My T-Mobile and visiting the PLAN section. For Pay in Advance (Prepaid) accounts, rates can be found on the Prepaid additional services page.
