No, a micro-SD card is a memory device, all it does is make the memory on your phone/ device larger. A SIM card is an individual device that has information such as your number, and contract details linked to it.
that is computeresting sim
No it's the handset that is a primary device
No it does not, that device is a CDMA device and only GSM devices use SIM cards.
As long as it is a GSM device and not a Nextel iDEN device then it will work as long as the device has been unlocked.
The function of a SIM card is relatively simple. It's not a super advanced item that controls your phone, rather, it is basically nothing more than a storage device for information useable by yourself and your cellular carrier. It has limited memory to save this information. And this 'storage device' is also the reason you can use someone elses phone, put your SIM card into it and have all of your phone numbers and information about your account on their phone. This is of course unless their cellular provider has SIM-locked their phones. Anyways, long story short SIM-Card = storage device.
A sim card has memory, depending on your specific one, from 32k to 128k. Sim cards are very small, a little over the size of a fingernail. Most sim cards come already made into your device and are mostly removable.
That means either your sim card is defective and it will not load the service or it means that the device is defective. Take it to the store and have them look at it
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.
Yes, It does , because it works on many different phone carriers...
