I am temporarily using an android phone while my iphone is being replaced. I am not receiving text messages to the android. I think i have to deregister imessage from my desk top. Will I have to re-register imessage when I receive my new iphone.
You need to de-register iMessage for now, you can activate iMessage once the iPhone is available for use.
Use an Android device and follow the GIF
Insert the same SIM into an Android . You may deregister iMessage online
Watch the GIF below. Here I have used another iPhone for the demo but for you, it may your choice. Android or iPhone device.
