About text messaging.
A text message is also known as an SMS (short messaging service). You can send a written message up to 160 characters from your own phone to another mobile or landline.
Your phone is automatically set up for sending and receiving text messages.
You can send text messages to other mobile phones or landlines. Some landline phones display text messages as they would on a mobile phone, but for those that don't we convert your text message into a voice message so that it can be listened to.
In some situations your device may convert a text message into an MMS (multimedia messaging service). These are charged outside of any text allowance you might have. Find out more about text message charges.
To find out how to send a text message, go to our device support and select your phone.
