What is the maximum size of a linked message?

You can type a linked message of unlimited length, but if there is a lot to say, it is better to choose an alternative way of communication – a call or an e-mail.  

The number of parts in a message are calculated as follows:
2 text messages = 160 characters + 146 characters
3 text messages = 160 characters + 146 characters + 153 characters

Please note! The maximum message length and the way it is sent may depend on the phone model and its settings. For example, on some Samsung phones, a long text message may automatically be converted to an MMS once it exceeds a certain length.
