Can you use a tracfone sim in iphone 2g?

Unfortunately, you cannot. Tracfone disables any unlocking of any of their SIM cards of any kind on any network, and you may or may not be penalized if you try. I suggest you unlock the Iphone 2G with T-Mobile, if you want lower-price service. I've heard THAT unlocking process is possible.


Is it possible to use a non-iPhone ATT SIM card with the iPhone 2g-- If so where is the card slot?

No. You have to jailbreak it. You can go on youtube on how to do that. Seach up blackra1n. It takes about 5 seconds. Go to the blackra1n app and then download sn0w. Then your iphone can be used with any carrier. The slot for the iphone is on the top between the lock and headphone jack. Use a small paper clip to open it. Hope this helped. Check out my youtube channel. Search up austinwangg on youtube.

What is the difference between 2g and 3g sims?

A regular SIM card comes with 32KB of onSIM memory which was sufficient to manipulate data on 2G network. but a 3G SIM card has 128KB of onSIM memory which is beneficial to handle high speed dat access just like more cache memory helps in faster processing. Otherwise there is no other difference between a 2G and a 3G SIM card.
