Say i buy a phone card for $25, i use all the minutes in a month, i buy another card, do i get a new number also? Or can i use the old one that i had?

You use the old one. Your phone number is tied to the SIM card.

And what company does 711 use for their service of providing networks on these cards?

It looks like Rogers'.

Say someone leaves a voice mail on my cell….how much do i pay to check it from my cell? and can i go home and diall some number and check it for free on my home phone?

The same rate applies, 25 cents per minute. You can check it free from a landline.

And what kind of are code numbers do you recieve? im in the GTA area…so 647??
Thanks in advance

416 and 647.

7-11 Speakout and Petrocan Mobility are both run by Ztar, who buys airtime from Rogers and uses their towers and network.
