Prepaid Mobiles

i am looking for a card with a low connection fee and also a low rate per minute. the problem is i need to call multiple counties over seas. can anyone recommend one, THANKS!

right now i have the lg white rumour,
can i transfer my phones plan so i can have the blackberry curve?
hope that makes sensee! thanks everyonee!

I need to know this for the following networks:
At&t
Sprint
Verizon
T-Mobile
Tracfone
Net-10
Pay-go (Boost Mobile)
And all other network providers that anyone knows of. I’m looking for a prepaid phone.

what phones can i use if I use cricket wireless? Do i have to specifically buy phones from cricket or can I buy prepaid phones from other companies like t-mobile, net 10 etc and use the cricket plan?

And also, there is a $25 deal for unlimited for cricket per month. Does that only last one month or like… forever?

Thanks
how do i know what phones are CDMA?

I just broke the display on my T-mobile prepaid cell and need to replace it. However, I just don’t like any of the prepaid phones T-mobile is offering at present. Can I buy a new prepaid phone from a different carrier and use my old SIM card with it?

Lets say, i bought a phone SGH-E360 (Samsung)
I wanted optus prepaid.. Do I HAVE to use their prepaid phones or can I just purchase the sim and insert it into my mobile?
-My phone is NOT on their prepaid phone list-

someone told me that if you have a virgin mobile or verizion prepaid phone, you can have it turned on by metro pcs, though it’s not a metro phone. could that be true?
thanks wireless guy! but if i no longer have service with sprint (under contract) and i still have a phone from them (which they tell you its useless), could i still have it activated with metro? i also have a tracphone that i don’t use, what about that one. Also, the person who told me that has a virgin mobile phone and she said she got it turned on with metro.
