Hi @fidelisakilan , @cscipher!

This is not due to the package, android versions or mobile devices. Actually, it's a network carrier issue.
You can identify this by going to settings > About Phone > Basic info (Phone number) and assure that you are not getting "Unknown Number" in the field. If you are getting "Unknown Number" then the package would return null, and the dialog will disappear.

Possible Solutions:

1. Eject your sim from android device and insert it into iPhone. Wait for few seconds for the sim info to get read by iPhone. Eject from iPhone and insert again in your android device. Hopefully, now you will be getting "" instead of "Unknown Number."

2. Some devices like HUAWEI, OPPO etc. has the ability to edit your sim numbers for "Phone Number Hint". You can do this by going to Network & internet > SIM card manager > Click on the pen (or any edit icon) > You can edit your number and save it.

3. Go to your Network Carrier Office.
