Yes the iphone 4 uses whats called a micro sim card it is smaller then the regular sim card out there. At www. phonetraderonline.com they can custom cut your existing sim card or provide you with a micro sim for your carrier.
just take the sim out and it works
no, you dont. you can jailbreak your iphone and run it on tmobile's network, if you have a tmobile sim card. but on tmobile, you cant have 3g speeds, only 2g.
You need one with a SIM Card slot. From there, find a GSM carrier, buy a SIM card and slip it in. (T-Mobile, AT&T, and every European carrier is GSM).
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.

yes but it is slow it is in 2g speed only but it is better than the cost of 3g plans
well im not really sure it unjailbroke it BUT it still works on my ATT sim but im not sure if its supposed to work on the iphone or not since its not a normal ATT sim card with a normal rate its not an iphone plan but it still works on it i dunno bout bootloader
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.
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.
haw we can convert 3g sim to 2g
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.
