SapphireIMEI

If you are rolling out your application on Smartphone or Pocket PC phone edition devices, you may wish to record the device’s International Mobile Equipment Identifier (IEMI) or International Mobile Subscriber Identity (IMSI) numbers. These numbers can be used to track what device and SIM card are being used by which user. It can also be used to ensure that the data on the device is kept unique by using the number as a device prefix within your data. The Sapphire IMEI Utility allows both the IMEI and IMSI numbers to be read from SmartPhone and Windows Mobile devices. You can download the latest demo version to see a fully working demo which you can reuse within your application as you see fit. This can be found on the download pages. The demo versions are fully functional and simply contain a popup message from time to time. These are ideal if you are selling your application to the client where you can be confident the application will work in practice and not just theory.

Sample Code

Implementation couldn’t be easier, simply declare the DLL function as a function within your application and call it as though you wrote it yourself. Here’s a sample demo to how to retrieve the device’s IMEI number within VB.NET.

Public Function IMEI(ByVal lDeviceID As Integer) As String

  Dim sIMEIStore As String

  Dim hInstance As Integer

  sIMEIStore = Space(100)

  sIMEI(sIMEIStore, hInstance, lDeviceID, SapphireIMEILicence)

  IMEI = StripString(sIMEIStore)

End Function

Dim sIMEI As String

Dim lDeviceID As Integer

For lDeviceID = 0 To 10

  lblDeviceID.Text = "Device ID is " & lDeviceID

  lblDeviceID.Update()

  sIMEI = IMEI(lDeviceID)

  If Len(sIMEI) >= 15 Then

    sIMEI = Mid(sIMEI, 1, 15)

    lblIMEI.Text = "IMEI Number is " & sIMEI

    lblIMEI.Update()

    Exit For

  End If

Next lDeviceID
