Class TelephonyManager

java.lang.Object
- android.telephony.TelephonyManager

```
public class TelephonyManager
extends Object
```
Provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.
You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE).
Note that access to some telephony information is permission-protected. Your application cannot access the protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the the methods through which you access the protected information.

```
public void listen(PhoneStateListener listener,
          int events)
```
    Registers a listener object to receive notification of changes in specified telephony states.
    To register a listener, pass a PhoneStateListener and specify at least one telephony state of interest in the events argument. At registration, and when a specified telephony state changes, the telephony manager invokes the appropriate callback method on the listener object and passes the current (udpated) values.
    To unregister a listener, pass the listener object and set the events argument to LISTEN_NONE (0).
    
    Parameters:
    listener - The PhoneStateListener object to register (or unregister)
    events - The telephony state(s) of interest to the listener, as a bitwise-OR combination of PhoneStateListener LISTEN_ flags.

```
public boolean isVoiceCapable()
```
    Returns:
    true if the current device is "voice capable".
    "Voice capable" means that this device supports circuit-switched (i.e. voice) phone calls over the telephony network, and is allowed to display the in-call UI while a cellular voice call is active. This will be false on "data only" devices which can't make voice calls and don't support any in-call UI.
    Note: the meaning of this flag is subtly different from the PackageManager.FEATURE_TELEPHONY system feature, which is available on any device with a telephony radio, even if the device is data-only.
  - isSmsCapable
```
public boolean isSmsCapable()
```
    Returns:
    true if the current device supports sms service.
    If true, this means that the device supports both sending and receiving sms via the telephony network.
