I am using MFMessageComposeViewController to send text message via my App. But I have a problem when we remove the SIM and try to send message. Is there any delegate available to track whether the message will be sent / not?
You can use the CTTelephonyNetworkInfo class of the core telephony framework to gather information about the SIM card. Use the subscriberCellularProviderDidUpdateNotifier method to get notified about SIM card changes:
A block object that is dispatched on
the default priority global dispatch
queue when the user’s cellular
provider information changes. This
occurs, for example, if a user swaps
the device’s SIM card with one from
another provider, while your
application is running.

Android - Huawei with HMS push plugin, HmsPushEvent.onRemoteMessageReceived this event was not triggered when app is in killed state. This event only getting called while app is in foreground and background state. Can you please tell which event will be called when app is in killed state.
Push Kit supports two types of messages: notification messages and data messages. After a device receives a data message, the device transfers it to your app instead of directly displaying the message. Your app then parses the message and triggers the corresponding action. Push Kit only functions as a channel, and the delivery of data messages depends on the resident status of your app. However, notification messages can still be delivered even if your app is not launched.
For the sake of saving power and not disturbing users, your app will not be launched by Push Kit after being stopped, and no data messages can be delivered to your app. In this case, you can determine whether to use notification messages based on your services.
To allow users to open a specified page of your app after they tap a notification message, proceed as follows:
Generate Intent parameters
Set intent in the message body on your app server
Register the Activity class to be started in the AndroidManifest.xml file of the app
Receive data in the customized Activity class

Alternatively, you can set high-priority data messages to forcibly launch your stopped app to receive and process the messages. To do so, you need to apply for special permission by referring to the related description in FAQs.
I am developing an app in swift in which when a customer places a order we have to notify the vendor about the order. So is it possible to call the vendor mobile through some api with a pre recorded message. More importantly will this app be accepted by the app store.
On iOS it is not possible to use the user's phone. You would have to use an API like https://www.twilio.com.
Use pushkit with local notification to notify user about incoming call in foreground , background or terminated state.
Then there are many supporting platform to join in VoIP call.

I am developing SIP and VoIP based iOS application and requirement is that the application should be continuously running even in background also.I am using pjsip lib.
I know that to run the iOS application in bacground,we need this
Set UIBackgroundModes key in Info.plist with voip value
Created a handler that I passed to setKeepAliveTimeout:handler: for
keeping the connection alive
But I just want that if my application is running in background can I receive UDP packets over (RTP/RTCP),while I am keeping UDP port always open.
I have already gone through the posts:
iPhone VOIP in background
VoIP socket on iOS - no notifications received
But,I have not getting clear idea that can we get UDP packet continuously even the app is in background or foreground.
So that if there is any data is coming to iOS client app , the app should be able to notify the user.
Please give suggestions.
In order to run VoIP app at the background and register on a server one should use TCP on iOS. When something happens you can fire local notification.
I think you can set local notifications when the app is running in background and indicate the user of an incoming call through the notification. When the user enters the application you can show the incoming call.
In the below link, check
Background Execution and Multitasking and also Scheduling the Delivery of Local Notifications
IE since you have set the UIBackgroundModes key in Your Info.plist, your app will support long running tasks. So in the applicationDidEnterBackground method add a method which creates a UILocalNotification when there's a call. UILocalNotifications notifies the user with an alert message and a tone of your choice. So once the user is notified and user enters the app, the app will come to foreground where you can add the method for him to receive the call.
In the alert body of the LocalNotification you can send the caller's information to the user.
EDIT : Check out the answer of Paul Richter in this link, where he says
VOIP mode gives you the ability to have code running to notify you of a call coming in
but you're not going to be able to record audio from the background. If you look at how
Voip apps work, when a call comes in a Local Notification is sent informing the user
that a call is coming in. The User then must accept the call which will bring the
application to the foreground at which point from the audio side of things you can
activate your session and proceed with the phone call.
Although not completely related to the library you are using, he has given a decent explaination of the process.
Hope this helps.
Currently I am developing an authentication module for my application. The user provides his phone number and a SMS with some pin code is send to him.
The user enters the code and if it is valid his phone number is authenticated. Maybe you know WhatsApp, it does quite the same when you run the app first time.
However if the user puts a new sim card in his phone he should authenticate it again.
I want to know how to determine if phone number has changed. I read in some other question that it is not possible to determine the phone number itself. But e.g. WhatsApp recognizes that there is another phone number.
Any ideas?
Update 2
One (not the best) way it's detecting carrier changing. Here you can see how to get carrier's name. Save it at first launch and do compare on next launches.
Update 3
I'd recommend to you look at Core Telephony Network reference and especially at CTTelephonyNetworkInfo reference
subscriberCellularProviderDidUpdateNotifier allow you respond on events such like:
... when the user’s cellular provider information changes. This occurs, for example, if a user
swaps the device’s SIM card with one
from another provider, while your
application is running
I want to use this function applicationWillResignActive perform some tasks.
before the application shuts down due to incoming call, message or user close it manually.
Can i send an email message/in app sms using this function ? Will those tasks would be performed or the application would immediately quit due to the above mentioned interrupts.
Thank you all.

Before sending email or sms on iOS you have to display standard UI to user (either MFMailComposeViewController or MFMessageComposeViewController), but you can't present any new UI when application is going to resign active state, so the answer is no - those tasks cannot be performed
