it goes in a phone
The best review for the 3G SIM card is the AT&T 3G SIM card. The newest 3G Wireless SIM card is the best and only costs $7.85. There is also a AT&T SIM card for $3.85.
You only need a SIM card if you've got a 3G version, and wish to subscribe to a 3G service. You do not need a SIM card at all for the wi-fi version, and if you had a 3G version but did not want a 3G subscription, you do not need a SIM card and it will function exactly like a wi-fi PSVita.
Yes You do need a sim Card
Yes, you can use a Flight 2 SIM card in an iPhone 3G, provided the SIM card is compatible with the network frequencies supported by the iPhone. The iPhone 3G is unlocked or locked to a network that supports the SIM card. Ensure that the SIM card is properly activated and configured for use in the device.
Its a SIM card that is used for 3g network.
You will have to contact Airtel to convert your 2G phone to 3G. The same sim card can be used for both 2G and 3G, so you will not need to change to a new card.

any sim card except 3g sim cards they will not work properly
Yes, a 2G SIM card is generally compatible with a 3G USB modem, as 3G modems are designed to support multiple generations of mobile technology, including 2G. However, the connection speed and performance will be limited to 2G capabilities since the SIM card does not support higher speeds. To fully utilize the benefits of a 3G modem, a 3G-compatible SIM card is recommended.
The i9 I bought does not support att 3g sim card. It would have been nice to know this before buying. They advertise that the phone works with any carriers, yeah right as long as you have an old sim card for att.the i9 phone does not support 3g serivce, meaning the web moves at a slower speed, but that doesn't mean you need an old sim card. i have a new at&t sim card that is 3g, & it works fine in this phone.
Yes
Of course, the iPhone 3G and/or the original iPhone will take any normal sim card; the 3G iPhone will take the 3G sim as well.
