I want to observe network changes from 4G to 5G use the following code:
if (@available(iOS 12.0, *)) {
[[NSNotificationCenter defaultCenter] addObserverForName:CTServiceRadioAccessTechnologyDidChangeNotification object:nil queue:nil usingBlock:^(NSNotification * _Nonnull note) {
}];
}
When I switch my phone's network from 4G to 5G, it do not work。but when I switch my network between 3G and 4G, it did work.
when I switch network to 5G,
I run CTTelephonyNetworkInfo.new.serviceCurrentRadioAccessTechnology ,it did return CTRadioAccessTechnologyNR which is 5G。
Question
is there a bug on CTServiceRadioAccessTechnologyDidChangeNotification when net changes between 4G and 5G?
is there a way to know network changes between 4G and 5G? Exclude polling。

How to Get CellID, MCC, MNC, LAC, and Network in iOS 13 from Objective c?
Post not yet marked as solved
I work for one of the networks. I am able to successful download the eSIM in iPhone for iOS 13.*.
Where I was taken to unknown state (CTCellularPlanProvisioningAddPlanResult) in iOS 14.0 always also it prompt the os screen to install eSIM("Set up Mobile Plan")
Please let me know why it take to unknown state always and why OS screen popup ?, please let me know if any configuration needed specific for iOS 14.x
Also attached the configuration & prototype code for your reference
hud.show(animated: true)
let plan = CTCellularPlanProvisioning()
self.request = CTCellularPlanProvisioningRequest()
self.request?.address = "" // SMDP Address
self.request?.matchingID = "" // Acitvation code.
if let validRequest = self.request {
weak var weakSelf = self
plan.addPlan(with: validRequest) {[weak self] result in
self?.hud.hide(animated: true)
switch result {
case .success:
weakSelf?.alertMessageToUser(title: "Hurray !...", message: "ESIM Downloaded Successfully")
print("Successful")
case .fail:
print("ESIM Download failed, contact your carrier")
case .unknown:
print("Unknown details, contact your carrier")
@unknown default:
print("Unknown details, CONTACT CARRIER")
}
}
}

All right, so I have an app that requires reading the data from the SIM card. More precisely I need the Carrier name, MCC, MNC, ISO Country code and current Radio Access Technology (Okay this does not directly come from the SIM card but it is linked). It works perfectly on every phone, but I realized (after testing) that I'm in trouble with the newest iPhones that have an eSIM set up. I have no idea how to tell my app to read the data of the physical SIM card instead of the eSIM.I tried to search a bit on the Web about that but I found absolutely nothing...The code I use:let telephonyInfo: CTTelephonyNetworkInfo = CTTelephonyNetworkInfo()
carrierNetwork = telephonyInfo.serviceCurrentRadioAccessTechnology?.first?.value ?? "null"
carrierNetwork = carrierNetwork.replacingOccurrences(of: "CTRadioAccessTechnology", with: "", options: NSString.CompareOptions.literal, range: nil)
let carrier = telephonyInfo.serviceSubscriberCellularProviders?.first?.value // actually here originally I tried to use ?.values.first, but the result is the same
let countryCode = carrier?.mobileCountryCode ?? "null"
let mobileNetworkName = carrier?.mobileNetworkCode ?? "null"
let carrierName = carrier?.carrierName ?? "null"
let isoCountrycode = carrier?.isoCountryCode?.uppercased() ?? "null"
/* so the problem is that the values I get are the ones from the eSIM when it is set up. If it is not, then I get the values I want. Apparently, when the physical SIM card line is set as primary, it works. But I need that code to systematically use the physical SIM data. */Example:I expect [physical SIM card]: Carrier name: Free, MCC: 208, MNC: 15, ISO Country Code: fr, CTRadioAccessTechnology: WCDMA.But instead, I get [eSIM]: Carrier name: Swisscom, MCC: 228, MNC: 01, ISO Country Code: ch, CTRadioAccessTechnology: LTE.EDIT: If you know how I can read both, that's also fine to me, my goal is to detect if the user uses a Free Mobile [208 15] SIM card.Thank you in advance,

Hi,I know this question has been asked before and it all ends up in the same "no-can-do" answer but I'm in the need to ask it myself to get evidence for the company I work for.I'm building an app (iOS with Swift) to keep track of my own cellphone usage to then compare it with my mobile plan, for that I need to get the duration and date of each call made from that phone. The only way to get that information that I could think of is by checking the phone's call history.Is there a way to get the phone's call history or log?Is there an iOS version in which this is or was allowed?Is there any public API to get this information form?Is there any way to get permission from Apple or some kind of entitlement to allow us to get it?According to some co-workers you could get that using CTCallCenter (CoreTelephony) but API Reference says it's deprecated (https://developer.apple.com/reference/coretelephony/ctcallcenter)I would really appreciate any information or facts provided.Cheers.

my IOS version is 9.0, Now i want to get the unique value of the Device, i think of using IMEI, but i did some tests, i always cannot get the IMEI of the device,could you tell me other ways to know unique value of the device?
