Sure. As long as your iPhone model has the SIM Card slot. Just make sure your LG uses Micro SIM Cards, or else you just have to cut your SIM Card to fit.
Yes, you will have access to all the features. It doesn't matter what SIM card is in your phone because the phone needs a SIM card, given to you by a carrier, that is supported by the phone to operate. Just put the SIM card in the HTC Wildfire and put it in the iPhone.
From iPhone 4 and beyond you can use simple software to unlock your phone. The 3GS is not able to unlock your phone unless you buy a special SIM card or take it to a different carrier
If your SIM card is not working in your iPhone 3G, you should check with the dealer you got the phone from. It may need to be unlocked for use with a different carrier.
An Apple iPhone 3GS can be purcased unlocked without a SIM card and used with a local carrier's SIM card. Once purchased it is as simple as inserting a SIM card from the carrier of your choice.
Well... if you have an unlocked iPhone, you can ditch roaming charges and grab a quick SIM card for Fido Mobile or something. Just slip it into your phone and begin using that carrier.
Another cellphone carrier would require literally taking your phone apart and inserting a SIM card of some sort, which would not be easy at all.
If your iPhone is unlocked, then yes, all carriers will work. But if it is locked to a certain carrier, then you will have to unlock it using a jailbreak.
No. Each carrier has allowed cell phones for their carrier. If you have a GSM carrier though, you can buy an unlocked phone to use on that carrier even if the carrier doesn't support the phone. All you do is move your sim card.
No
Some people buy a pre-paid SIM card for the mobile phones and it works in another country. Is it possible to insert a SIM card in any smartphone such as iPhone, HTC, Samsung, etc? There are phone companies selling the pre-paid model which comes with the phone and the pre-paid SIM card. I want to use the existing smartphone like iPhone with it. Is it possible that I simply purchase the cheapest model if the shops don't sell SIMs only and insert the card into the regular phone?
The answer to this questions varies by the specific hardware and carrier's involved, but generally would be rather difficult to accomplish for an average consumer. Ask the new carrier if they would be able and willing to activate the existing air card on their network - the existing card may not even be technically compatible with the new carrier's network.
