Questions people ask
The three that come up most. The full list lives on the FAQ page.
Every letter, number, space and punctuation mark in the text you send. A sentence of forty letters and spaces is forty characters. Only the text that is actually spoken counts.
Reading stops until the next month begins, and then your 10,000 characters are back. Nothing is charged and nothing is deleted. To keep going inside the same month, you buy credit.
The free 10,000 are a monthly allowance, so they reset every month instead of piling up. Credit you paid for is different: it never expires, and it stays on your account until you spend it.
