[wmardian]

Dear All,

I already try searching in this forum, and all solution told me to use phoneId to get the phone number. But it seem i can not use this solution.. maybe there is something wrong with my code..

Sub Button1_Click
   
    Dim ph As PhoneId
    Dim phoneNumber As String
   
    phoneNumber = ph.GetLine1Number
    Label1.Text = phoneNumber

Please find attached picture.. from my debug that show the value is just empty.

Your help will be very appreciated.
Thanks and Regards

have you added the following permission to you manifest file ?

android.permission.READ_PHONE_STATE

 

[Erel]

The permission should be added automatically unless the manifest file is set to be read-only.

Dear Erel,
I connect the IDE to my lenovo P780 with dual sim card.
But i also found another thread in this forum and they also have the same problem..

Thanks and Regards

GetLine1Number calls the native API to get the phone number. If the number is not available then it returns an empty string.

It is impossible to say why the number is considered not available in this case.

Dear Erel,
Many thanks.

Do you have any idea what i should do now? or is there another way to do this? my lenovo P780 loaded with kitkat...

Thanks and regards

Hi,
Could the phone number not been returned only because the SIM card does not know it ? Some operators won't write the phone number into the SIM card.

Hi lemonisdead,
if it is the case, then what should we do to get the number or the identity of the phone which always return valid value?

You dont need the telephone-number to identify a device... You can use the imei and/or SubscriberID...

Dear Don,
thanks for the idea.. anyway, why do they keep trying to find how to find the phoneID if they can use imei?

Thanks a lot..

a telephone-number is more worth. you cannot call the imei to send an offer-sms to this device for example....

 

[wmardian]

Dear Don,
We are still trying to find alternative to getDeviceID and getLine1Number because there are some device which do not return correct value using these method..

Wmardian, have you tried GetSimSerialNumber ? This should work if there is one inserted

Will back to you with the result..
