Xamarin iOS - Check if mobile data connection is available - objective-c

Question

I would like to check if mobile data is available (the app has access, it's switched on in settings, aeroplane mode isn't on and there is a valid connection).
I want to know this even when an active wifi connection is established. So I can't use any get the current connection as it won't be the current one, WiFi would be.
I have tried looking into NWPath and NWPathMonitor but got a bit confused by it all.
Thanks, if I need to add any more information just drop a comment and I will update this or reply to you.

Answer 1

Since you have a Tag with Xamarin, just use the API from Essentials. For the connectivity-checker see the docs.
Here is a pretty perfekt blogpost from "James Montemagno"
A sneak preview of the Post:
var current = Connectivity.NetworkAccess;
switch(current)
{
case NetworkAccess.Internet:
// Connected to internet
break;
case NetworkAccess.Local:
// Only local network access
break;
case NetworkAccess.ConstrainedInternet:
// Connected, but limited internet access such as behind a network login page
break;
case NetworkAccess.None:
// No internet available
break;
case NetworkAccess.Unknown:
// Internet access is unknown
break;
}
Edit due to the comment from #Samuel James:
Maybe this helps?
Check what type of activ connection (according docs from Mircosoft):
var profiles = Connectivity.ConnectionProfiles;
if (profiles.Contains(ConnectionProfile.Cellular))
{
// Active mobile/cellular data connection.
}
public enum ConnectionProfile
{
/// <summary>Other unknown type of connection.</summary>
Unknown,
/// <summary>The bluetooth data connection.</summary>
Bluetooth,
/// <summary>The mobile/cellular data connection.</summary>
Cellular,
/// <summary>The ethernet data connection.</summary>
Ethernet,
/// <summary>The WiFi data connection.</summary>
WiFi
}

Answer 2

See my answer here ,we can use CoreTelephony framework to get what the specific type of cellular is .
Try the following code
public ConnectivityTest()
{
// Register for connectivity changes, be sure to unsubscribe when finished
Connectivity.ConnectivityChanged += Connectivity_ConnectivityChanged;
}
string result;
void Connectivity_ConnectivityChanged(object sender, ConnectivityChangedEventArgs e)
{
var access = e.NetworkAccess;
var profiles = e.ConnectionProfiles;
if (Connectivity.NetworkAccess != NetworkAccess.Internet)
{
result = "NoNetworkAccess";
}
else if (profiles.Contains(ConnectionProfile.Cellular))
{
CTTelephonyNetworkInfo networkInfo = new CTTelephonyNetworkInfo();
string carrierTypeName = networkInfo.ServiceCurrentRadioAccessTechnology.Values[0];
if (carrierTypeName == null) result = "unknown";
else if (carrierTypeName == CTRadioAccessTechnology.GPRS ||
carrierTypeName == CTRadioAccessTechnology.Edge ||
carrierTypeName == CTRadioAccessTechnology.CDMA1x)
result = "2G";
else if (carrierTypeName == CTRadioAccessTechnology.WCDMA ||
carrierTypeName == CTRadioAccessTechnology.HSDPA ||
carrierTypeName == CTRadioAccessTechnology.HSUPA ||
carrierTypeName == CTRadioAccessTechnology.CDMAEVDORev0 ||
carrierTypeName == CTRadioAccessTechnology.CDMAEVDORevA ||
carrierTypeName == CTRadioAccessTechnology.CDMAEVDORevB ||
carrierTypeName == CTRadioAccessTechnology.EHRPD)
result = "3G";
else if (carrierTypeName == CTRadioAccessTechnology.LTE)
result = "4G";
else result = "5G";
}
}
