Where to Buy a PrePaid SIM?

[JeffreyVB]

Can anyone recommend a reputable dealer with a good deal on a T-Mobile Prepaid SIM? Found a 100min SIM card for $20 online. Does this sound like a decent deal? Will it work in a Berry (for voice only, of course).

Sounds like they're just dressing up one of the normal prepaid packages. Walk into any corporate store and you can buy a prepaid SIM card and activation kit for $10. The SIM card will automatically come with $3.34 worth of airtime on it. The plan they're using costs $1 a day on days the phone is used. You get free calling to anyone on TMO, free calls to anyone in the US after 7 pm, and any other calls are $.10 per minute. With their package, you're just buying an additional $10 airtime card.
