📱 Carrier Info

⚠️ IMPORTANT iOS 16.0+ NOTICE: Apple has deprecated CTCarrier starting with iOS 16.0. This means that most carrier-specific information (carrier name, country codes, network codes, etc.) will return nil or generic values on iOS 16.0 and later versions. This is an Apple platform limitation, not a plugin issue. See the iOS Limitations section for more details.

Carrier Info gets networkType, networkGeneration, mobileCountryCode, mobileCountryCode, e.t.c from both android and ios devices. It's a port from this js project and an improvement on the existing flt_telephony_info package.

iOS Features

Available on All iOS Versions

SIM Detection

• isSIMInserted: Boolean indicating if a SIM card is inserted and active
• networkStatus: Real-time network connectivity information
• carrierRadioAccessTechnologyTypeList: Current radio technology (2G, 3G, 4G, 5G)

Network Status

"networkStatus": {
  "hasCellularData": true,        // Cellular data available
  "activeServices": 1,            // Number of active cellular services
  "technologies": ["LTE"]         // Current radio access technologies
}

Subscriber Information (iOS 16.0+)

"subscriberInfo": {
  "subscriberCount": 1,                           // Number of subscribers (dual SIM)
  "subscriberIdentifiers": ["subscriber_id"],     // Subscriber identifiers
  "carrierTokens": ["token"]                      // Carrier authentication tokens
}

Cellular Plan Information

"cellularPlanInfo": {
  "supportsEmbeddedSIM": true     // eSIM support detection
}

iOS Version Detection

Use the _ios_version_info field to detect capabilities:

final iosInfo = await CarrierInfo.getIosInfo();
final versionInfo = iosInfo?.toMap()['_ios_version_info'] as Map<String, dynamic>?;
final isDeprecated = versionInfo?['ctcarrier_deprecated'] as bool? ?? false;

if (isDeprecated) {
  // Handle iOS 16.0+ limitations
  print('SIM Inserted: ${iosInfo?.isSIMInserted}');
  print('Network Status: ${iosInfo?.networkStatus?.hasCellularData}');
  print('Radio Tech: ${iosInfo?.carrierRadioAccessTechnologyTypeList}');
} else {
  // Full carrier information available
  print('Carrier: ${iosInfo?.carrierData?.first.carrierName}');
  print('MCC: ${iosInfo?.carrierData?.first.mobileCountryCode}');
}

iOS Limitations

CTCarrier Deprecation (iOS 16.0+)

Starting with iOS 16.0, Apple has deprecated the CTCarrier class and related APIs for privacy and security reasons. This affects the following information:

❌ No longer available on iOS 16.0+:

• Carrier name (carrierName)
• Mobile country code (mobileCountryCode)
• Mobile network code (mobileNetworkCode)
• ISO country code (isoCountryCode)
• VOIP allowance (carrierAllowsVOIP)

✅ Still available on iOS 16.0+:

• SIM insertion detection (isSIMInserted)
• Radio access technology types (carrierRadioAccessTechnologyTypeList)
• Network status (networkStatus)
• Subscriber information (subscriberInfo)
• Cellular plan information (cellularPlanInfo)

Recommendations

1. Check iOS version: Use the _ios_version_info field to determine if you're running on iOS 16.0+ and handle the limitations accordingly.

2. Use available features: Focus on features that work across all iOS versions:

   // These work on all iOS versions
   final simInserted = iosInfo?.isSIMInserted ?? false;
   final hasData = iosInfo?.networkStatus?.hasCellularData ?? false;
   final radioTech = iosInfo?.carrierRadioAccessTechnologyTypeList ?? [];
   

3. Graceful degradation: Design your app to work without carrier-specific information on newer iOS versions.

4. Alternative approaches: Consider using network-based detection or user input for carrier information when needed.

5. Android alternative: For apps that require detailed carrier information, consider using the Android implementation which still provides full functionality.

New iOS Models

The plugin now includes enhanced models for iOS data:

• IosCarrierData: Main container with all carrier information
• CarrierData: Individual carrier information (nullable fields for iOS 16.0+)
• SubscriberInfo: Subscriber and carrier token information
• CellularPlanInfo: Cellular plan provisioning information
• NetworkStatus: Real-time network connectivity status

Permissions

You should add permissions that are required to your android manifest:

  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  <uses-permission android:name="android.permission.READ_BASIC_PHONE_STATE" />
  <uses-permission android:name="android.permission.READ_PHONE_STATE" />

  <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />

✨ 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 around it and it's super complex.
