Our app is payment related app & we are doing device binding. So, based on sim detection we have implemented feature for device binding. If sim is not present in device then, we have to show alert to the user for "No sim found". As per current deprecation in CTCareer, We are always getting static details for sim card, so we are not able to detect, either sim is there or not in device. Is there any solution to detect sim is there or not in device?

In the Apple's documentation link below, it says CTCarrier is deprecated. Does this mean this class wouldn't work on iOS 16.0+ or iOS 17+. Notice, in the web page, it says "iOS 4.0 - 16.0 Deprecated." This makes me wonder if this API wouldn't work on iOS 17+ Any help is appreciated.

Hello, I work for a USA cell phone carrier and we have our own SIM cards. We'd like to add a carrier bundle so we can have our carrier settings predefined in iOS devices. Could someone explain what the process is? Thanks

Hi I'm developing a full-duplex iPhone voice chat application and I'd like to intercept bluetooth headset button events to perform certain actions in my app while maintaining a full-duplex audio. I'm using the MediaPlay to intercept remote bluetooth AVRCP MPRemoteCommandEvent play/pause events as well setting AVAudioSession to use the BluetoothA2DP category, however, when I do this, I can't seem to use the bluetooth microphone as an audio input. Specifically, when I query AVAudioSession for available inputs, bluetooth is not returned. I'm guessing this is because A2DP is a half-duplex protocol, but my understanding is that AVRCP events are only available with A2DP. The other bluetooth profile choice is HSP (AVAudioSession category Bluetooth), which works for full-duplex audio, but does not appear to provide a way to intercept the various AT commands from this profile unless I'm in an actual telephone call. For example, when I use HSP and press a button on my headset, I see in the logs the AT+CHUP command being sent from the headset to the phone. Two questions: Is there a way to use a bluetooth microphone while using A2DP for output at the same time? If the above can't be done, is there a way to intercept the HSP AT control commands from a headset without being in a telephone call? Thanks.

I am working for an MVNE/MVNA In September 2022, I filed an eSIM Access Entitlement request through the Apple Developer Portal. I didn't receive any feedback from Apple, and we can't see access given as yet. how do I follow up with this? Who do I contact? We have a customer going live in 2 weeks and we need this enabled. We have reached out to our partner carrier and they have not heard anything either. Thank you

b4 IOS 17 can detect sim card swap with 'CTTelephonyNetworkInfo' but after update IOS 17 can not use this library is there anyway to dectecting swapping the sim?

Hi Everyone, I am working on an app where I need to determine if a call whether incoming or outgoing is a normal (cellular) call or VOIP call? And yes, if we can identify if it's a VOIP call, can we also identify the name of the app used for the call?

Hi, I am using the below code CXCallObserver *callObserver = [[CXCallObserver alloc] init]; for(CXCall* call in callObserver.calls) { if(call != nil) { } } Is there a way we can determine if it is a voip or call or not.

I think it is about time iCloud Backup should be extended to enable Cellular Data be enabled for it's data Use. My Understanding has been those from Africa and other less highly technological places have had it difficult in backing up their phones on iCloud due to the exclusive request for Wi-Fi. At these places Cellular data is mostly the source of readily source for for all internet connectivity's. So I think there should be a conscious effort to allow iCloud Backups through Cellular Data.

Hi, We have an app passing digits once connected to the PBX. We are simply dialing (***) ***-xxxx, yyy. After upgrading to Rls 16.4 PBX is no longer correctly decoding "yyy" digits represented by DTMF. If we press digits manually it works correctly, which leads us to conclude, Rls 16.4 sends to short DTMF. Upgrade to 16.4.1 didn't fix that bug. Peter

Hi to everyone, I'm trying to implement on my app the process to install eSIMs directly from my app. We have been authorized by Apple to use the CoreTelephony framework, and I've already implemented the functions but I need to compile first the the CarrierDescriptors Key in the info.plist file. CarrierDescriptors <dict> <key>MCC</key> <string>’mnc value’</string> <key>MNC</key> <string>’mnc value’</string> </dict> </array> Now the point is, that we are just a reseller of eSIMs, so we are not the real carrier, and so we don't have our MCC or MNC values. So what could or should we write there? Our providers should give us those data based on the carriers who provides them the eSIMs? Thanks a lot for any help or advice!
