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, you can use a 2G Airtel SIM in a 3G Airtel dongle without unlocking it, as most 3G dongles are backward compatible with 2G networks. However, the dongle will only provide 2G speeds and services, as it will operate according to the capabilities of the SIM card. Ensure that the dongle is compatible with the frequency bands used by the 2G network in your area.
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.
To convert a BSNL 3G SIM to a 2G SIM, you need to visit a nearby BSNL customer service center or retailer. Bring your ID proof and the existing 3G SIM card. Request the conversion to a 2G SIM, and they will provide you with a new SIM that supports 2G services. There might be a nominal fee for the new SIM, and activation could take some time.
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.
