I have the monthly pre-paid plan (currently $18 / month) and a ZTE Cymbal2 flip-top phone.
When sending SMS text messages, sometimes a pair of numbers pops up on the phone, and the first of the pair starts counting down towards zero as I type, which I assume is some kind of limit on how much or how many characters or messages I am currently allowed to send.
What limits are there for sending SMS text for this plan and are these numbers somehow indicating that I am nearing one or other of these limits?
Cheers, John Lumby
