With a $75 or $100 card you get a 20% bonus. So that's 20% more minutes, 20% more texts, etc etc.

Actually it's 25% more, e.g. $125 credit on a $100 top-up, so you get 25% more texts, etc.

Or you can look at it like all the costs are lowered by 20% - per minute rate is 20cents, monthly fee is 80cents, texts are 4cents, etc.

If you're going to use at least $75 in airtime/texts/whatever per year, then get a $75 or $100 card if you can.

Please also note the chart on the home page of this site, under the heading "Summary of "effective rates"

i only use my phone for text, so i guess buying the $75/$100 airtime card won't help me much since it only lowers the min rate, not the text rate?

ALL SpeakOut airtime refills last 365 days. They tried to introduce a top-up voucher that cost $15 and had an expiry date of 30 days, but that was cancelled before it really got going (thanks to the outcry brought on by users of this site)

I have found unfortunately 7-Eleven clerks can be clueless. I talked to a clerk at a 7-Eleven once, and he said he was unaware of SpeakOut!

Rest assured, no matter what denomination of top-up you buy, they all last 365 days.

Your voucher should say right on it "$25/$50/$75/$100 expire 365 days after activation.

Rates

Talk for as little as 20¢/minute; text for 5¢. And with SpeakOut, your time is yours, good for a full 365 days, and any unused time rolls over when you buy more. Airtime can be purchased in 4 denominations. Check 'em out.

but i just called the don mills 7-11 and they said the $25 airtime they sold was 365 day expiry. which is should be right?

it's my first time to buy airtime, i started using speakout with a sim that already had mins on it.
