SMS Character Counter

SMS messages can have no more than 160 characters

On some wireless carriers, due to a programming convention called percent-encoding, certain symbols require more than one character when used. For example, the symbol “&” will display as one character when viewed on a mobile device, but actually requires the use of three characters to implement. The character counter below takes these factors into account—feel free to use it when building messages for your next campaign.

Other symbols in this category include:

@ # $ % & [ ] ; : , ? + = /

Hi, your description says that the & should count for 3 characters, but the counter only counts it as 1. Also, where can I find more information about symbols and their character counts? Everywhere else I’ve looked online and on my iPhone, these symbols count as one character. Thanks- Brooke
