looking for prepaid cell plan

Hi, i was thinking about a pre-paid service plan, cuz i would use my cell very rare. Which plans has longer time of use, i mean if i pay $30 for a card, which company gives me longest time to use this 30$? I have unlocked cellphone. Livin' in new jersey

Sti mobile is good for pre-pay. i think staples sells thier stuff. $0.10 per day + mins. .05- texts 1 min -$.10. If you have good sprint coverage, you should have good stimobile coverage.
some of the phones are free. very limited selection. don't know if you could use your unlocked phone.
STi Mobile

Looks like STi Mobile operates on the Sprint network which uses CDMA. Couldn't use an unlocked GSM phone with them.

When looking for a prepaid mobile phone

consider these following
1)price of the card
2)time of expiry of the card
3)call charges

These are the two most important factors in deciding the choice of prepaid cell plan

do you mean 3 most important? lol

I bet you're just supposed to pick two out of the three and run with them.

Yes spum you are right not all are important these are thne main factors that should be considered

Liberty Wireless Prepaid Plans are pretty good.
