Access the SIM Card with an Android Application?

Question

I wonder if it's possible to access to the SIM card with an Android Application

You need to ask much more specific questions. What is it about the SIM card that you want to access? — CommonsWare, Mar 03 '10 at 18:11

You can get the IMEI like this (but is it what you want ?), just an exemple :

mTelephonyMgr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String imei = mTelephonyMgr.getDeviceId();

Likewise, you have

String getSimCountryIso():

Returns the ISO country code equivalent for the SIM provider's country code.

String getSimOperator(): Returns the MCC+MNC (mobile country code + mobile network code) of the provider of the SIM.

String getSimOperatorName(): Returns the Service Provider Name (SPN).

String getSimSerialNumber(): Returns the serial number of the SIM, if applicable.

int getSimState(): Returns a constant indicating the state of the device SIM card.

String getSubscriberId(): Returns the unique subscriber ID, for example, the IMSI for a GSM phone.

For more, take a look at this page

and don't forget to add the correct permission in the manifest (getDeviceId() => Requires Permission: READ_PHONE_STATE)

IMEI is associated with the phone device, not the SIM card. – Martin Paljak Mar 08 '10 at 08:47
But Can I send APDU command to the SIM Card to communicate with a javacard application? – Adrien Mar 11 '10 at 13:01
This is an SmartCard Communication Framework, which doesn't let you change the telephonenumber. – sweisgerber.dev Jul 26 '12 at 08:17

Without SmartCardAPI from SEEK(Secure Element Evaluation Kit) its never possible. In majority Android phones available in market SmartCardAPI is not implemented. So either you build your own Android after integrating the SmartCardAPI code or wait for some decent phone with this feature to come out. You can find the patch file for implementation here.

SIM card access is only possible for system applications:

Low level access to the SIM card is not available to third-party apps. The OS handles all communications with the SIM card including access to personal information (contacts) on the SIM card memory. Applications also cannot access AT commands, as these are managed exclusively by the Radio Interface Layer (RIL). The RIL provides no high level APIs for these commands.

SEEK is most useful one,but majority Android phones are not support that.So,maybe we can assess SIM card by some other method like read SMS(in SIM card).
