hello, I work for a telecommunications company specializing in signal quality and field testing. We need to collect radio signal level measurements and L3 traces with iPhones. Since the chipset in the latest models is Qualcomm, we believe there is a possibility of using QXDM, but we're not sure how to proceed.

Hi, Need information on the Esim entitlement, we are planning to get the Esim Entitlement for our App, as part of the same when we try to submit there is field "Carrier Partner Team ID" while trying to submit request, we have reached out to our carrier on the same, meanwhile would like to understand what the field is refers for. Regards, Sunil Reddy.

Hi, I'm developing a feature for a carrier company, I have to find out whether the iPhone is sim-free (unlocked). How can it be done programmatically? I tried to look at the CTCarrier class but it seems to be deprecated and we cannot count on the information it provides. What would be the right APIs/Classes to use for it? Thanks in advance

Hi. I would like my App to be notified when the phone rings. No, not CallKit-CallKit is for VoIP and does not cover Cellular connections (as of 2/26/24) but, thanks. To continue.. I understand ages-ago there was a Telephony Kit or Framework but, has been discontinued. Has it been replaced with something else? I would like something that seems very simple:a) when the phone rings my App is notified, b) when it stops ringing (combine all possibilities; sent to voicemail, user cancels, user answers) my App is notified. Yes, I understand UserNotifications can make things run but, as I understand it this feature is for the App to schedule notifications, not receive them? If you know of something in UserNotifications that I can leverage I would appreciate your input. Lacking other possibilities I find myself wondering about Siri integration. Siri is notified about system events and generates notifications based upon these events. Is there some way to place my App downstream from Siri and receive system notifications? Thanks everyone.

In order to get more accurate compass data it seems that iOS devices with a simcard installed can provide better results. To distinguish between data delivered I would like to retrieve a status telling me if there is a simcard available and connected to the mobile network or not. All recommendations are pointing to the deprecated CoreTelephony functions which are obsolete since I am working with iOS17 devices. Is there a way to check if the device uses a simcard or not?

Hello! Firstly, I am submitting an entitlement request to access the E-sim configuration for the iOS application. While filling out the form, I encountered an issue with providing carrier information. The form is designed for a single carrier, but I have five carriers. Should I list all of them? Secondly, I have come across numerous discussions online regarding the time it takes to process such requests. Could you please provide me with an estimated timeframe for completion? Our customer is interested in completing the feature within a month. Thanks

Hello everyone! Since iOS 17.4, it's now easier to set up an eSIM from a browser/email or with a link. We can now longpress the QR code to get the option to add an eSIM. Is it still required to have that private entitlement to enable the same functionality in-app but not in a browser? Seems odd. I can store QR codes on Imgur to install eSIM but can't do the same with my native app by CTCellularPlanProvisioning.addPlan method. Redirecting users to the browser seems like a workaround, but it creates a noticeable discrepancy in usability. I might have overlooked some SDK updates or new methods. Are there any new approaches to enable in-app eSIM setup with the latest update? Secondly, in the "Other eSIM activation methods" section of this page, a special link is mentioned, but I couldn't find any examples or resources for that. Thanks

Hello, I am trying to develop an app , using Flutter. My app has its own database which it contains the customer info such as name, address and phone number. I need to get the caller's phone number then I use the phone number and search in my database and if the phone# exist in our DB , I extract customer info and show it on pop up screen. How can I get the phone number of the person who is calling? i tried this, it didnt work: let networkInfo = CTTelephonyNetworkInfo() guard let carrier = networkInfo.serviceSubscriberCellularProviders?.first?.value else { return nil } return carrier.mobileNetworkCode Is there any way to get caller's number while he/she is calling? Thanks P.

I have an application that needs to make a USSD call, but on some devices the * and # don't work on the dialer, on others it does. if let phoneNumber = ussdNumberTextfield.text { let encoded = "telprompt:\(phoneNumber)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)! if let url = URL(string: encoded) { if application.canOpenURL(url){ DispatchQueue.main.async { self.application.open(url, options: [:]) { success in } } } } }

I need to obtain the user's EID within my app. We are a mobile network operator and have also applied for Apple's eSIM development. Does Apple provide a certified developer access to an API for obtaining EID? I understand that there is no public API available, but I'm unsure if approved operators can access EID. If so, how can I apply for this private API?

Hi, we are a Carrier company (Utility provider) and working on a feature to display real-time Wifi Signal strength of customer devices (connected to Router Gateway) to help customers identify low and high signal areas, and possibly install extenders to improve signal strength at weak points. This feature requires NEHotspotHelper entitlement approval to access signalStrength property. We went through this Apple documentation too and we're open to other recommendations from Apple https://developer.apple.com/forums/thread/721067 . Since we currently don't have direct point of contact with Apple to discuss this requirement, hence wanted to check it here. Kindly advise. Thanks !

Hello, I am developing a private internal Flutter app for our customer, which will not be published on the Apple Store. One of the key features of this app is to collect RF strength metrics to share user experience with the network. For Android, we successfully implemented the required functionality and are able to collect the following metrics: Signal strength level (0-4) Signal strength in dBm RSSI RSRQ Cell ID Location Area Code Carrier name Mobile country code Mobile network code Radio access technology Connection status Duplex mode However, for iOS, we are facing challenges with CoreTelephony, which is not returning the necessary data. We are aware that CoreTelephony is deprecated and are looking for alternatives. We noticed that a lot of the information we need is available via FTMInternal-4. Is there a way to access this data for a private app? Are there any other recommended approaches or frameworks that can be used to gather cellular network information on iOS for an app that won't be distributed via the Apple Store? my swift code import Foundation import CoreTelephony class RfSignalStrengthImpl: RfSignalStrengthApi { func getCellularSignalStrength(completion: @escaping (Result<CellularSignalStrength, Error>) -> Void) { let networkInfo = CTTelephonyNetworkInfo() guard let carrier = networkInfo.serviceSubscriberCellularProviders?.values.first else { completion(.failure(NSError(domain: "com.xxxx.yyyy", code: 0, userInfo: [NSLocalizedDescriptionKey: "Carrier not found"]))) return } let carrierName = carrier.carrierName ?? "Unknown" let mobileCountryCode = carrier.mobileCountryCode ?? "Unknown" let mobileNetworkCode = carrier.mobileNetworkCode ?? "Unknown" let radioAccessTechnology = networkInfo.serviceCurrentRadioAccessTechnology?.values.first ?? "Unknown" var connectionStatus = "Unknown" ... ... } Thank you for your assistance.
