+# 📱 Carrier Info
+
+Carrier Info gets networkType, networkGeneration, mobileCountryCode, mobileCountryCode, e.t.c from both android and ios devices. It's a port from this [js project](https://github.com/react-native-webrtc/react-native-carrier-info) and an improvement on the existing [flt_telephony_info  package](https://pub.dev/packages/flt_telephony_info).

+
+### allowsVOIP (iOS only)
+
+```dart
+ bool carrierInfo = await CarrierInfo.allowsVOIP; // Indicates if the carrier allows VoIP calls to be made on its network.
+```
+
+- If you configure a device for a carrier and then remove the SIM card, this property retains the Boolean value indicating the carrier’s policy regarding VoIP.
+- Always return `true` on Android.
+
+### carrierName
+
+```dart
+ String carrierInfo = await CarrierInfo.carrierName;  // The name of the user’s home cellular service provider.
+```
+
+- This string is provided by the carrier and formatted for presentation to the user. The value does not change if the user is roaming; it always represents the provider with whom the user has an account.
+- If you configure a device for a carrier and then remove the SIM card, this property retains the name of the carrier.
+- The value for this property is 'nil' if the device was never configured for a carrier.
+
+### isoCountryCode
+
+```dart
+String carrierInfo = await CarrierInfo.isoCountryCode;  // The ISO country code for the user’s cellular service provider.
+```
+
+- This property uses the ISO 3166-1 country code representation.
+- The value for this property is 'nil' if any of the following apply:
+  - The device is in Airplane mode.
+  - There is no SIM card in the device.
+  - The device is outside of cellular service range.
+
+### mobileCountryCode
+
+```dart
+String carrierInfo = await CarrierInfo.mobileCountryCode;  //The mobile country code (MCC) for the user’s cellular service provider.
+```
+
+- MCCs are defined by ITU-T Recommendation E.212, “List of Mobile Country or Geographical Area Codes.”
+- The value for this property is 'nil' if any of the following apply:
+  - There is no SIM card in the device.
+  - The device is outside of cellular service range.
+- The value may be 'nil' on hardware prior to iPhone 4S when in Airplane mode.
+
+### mobileNetworkCode
+
+```dart
+String carrierInfo = await CarrierInfo.mobileNetworkCode // The mobile network code (MNC) for the user’s cellular service provider.
+```
+
+- The value for this property is 'nil' if any of the following apply:
+  - There is no SIM card in the device.
+  - The device is outside of cellular service range.
+- The value may be 'nil' on hardware prior to iPhone 4S when in Airplane mode.
+
+### networkGeneration
+
+```dart
+String carrierInfo = await CarrierInfo.networkGeneration // 5G, 4G ... 2G
+```
+
+### radioType
+
+```dart
+String carrierInfo = await CarrierInfo.radioType // LTE, HSDPA, e.t.c
+```
+
+## ✨ Contribution
+
+ Lots of PR's would be needed to make this plugin standard, as for iOS there's a permanent limitation for getting the exact data usage, there's only one way arount it and it's super complex.
