A phone card usually refers to a kind of charge card, something you pay with. A SIM-card is what gives a cell phone its number, it's identity.

SIM cards do not always work for any cell phone, as most wireless providers lock their phones to their specific network. Putting a SIM card into a cell phone locked to a different company usually triggers a service provider lock. Usually, the only way to get around this is getting the unlock code from the wireless provider it was originally used with, which they may not allow. In addition, some cell phones, usually CDMA, do not even have a slot for a SIM card.

GSM stands for Global System for Mobile Communications. This type of telephone service enables anybody to access cellphone networks anywhere in the world. If you are travelling, all you need is to buy a chip called SIM card that works in the country that you're going, put it inside the card slot in your cellphone and you will be able to use your cellphone in that country.

Yes, SIM cards can be reused for other phone plans, whether they are on the same network or not. If you are changing network provider, you will need to request the NAC or network access code from your current provider.

Yes , i phone 4 want micro sim ,Because there are now several countries where the iPhone 4 is sold unlocked, everyone can choose the best network and tariff for their needs while not tying themselves down to a long contract. There is no doubt that this is the way phones should be sold, however, buying the iPhone 4 in this way has a distinct problem all of its own: the micro-SIM card.

If you are talking about the iPhone, then no. The unlocked iPhone will ONLY be able to run on GSM networks, such as AT&T, in the US. It will not run on CDMA craaiers, such as Verizon or Sprint. This goes for all 3 2012 current iPhone models: iPohne 3GS, iPhone 4, and iPhone 4S. It may also apply to other phones ( e.g. the nexus line of phones, and the htc one S/X

The cut mark on the corner is to avoid the misalignment of the contacts of SIM card and mobile phone cardholder pins. Pin number 1 of the SIM card to make the contact with the corresponding pin of the mobile phone. The cut mark serve as a guide for proper placement of card in mobile phones.

HI,

This is the good Query. If we enable the service to Transfer money from One

sim to another sim within Same Network or between different Networks, it will

be so helpful under many circumstances. For this service some charge will be taken. but the process is under processing, we may expect it soon from various

competitors in the market. Hope to get it soon.

yea i have gotten several phones from att and used the same sim card for all of them, and kept the same phone number.

Because in the US all GSM devices (ones that require a SIM card) are SIM locked to their respective carrier (AT&T or T-mobile). Before you can use your SIM in another carrier's device you must get the SIM Unlock Code (some call it a Subsidy Unlock Code) from the service provider that the device was manufactured for and then they will also give you the instructions for inputting the code into your device.
