This issue can happen if you use your new iD SIM card and phone, before switching the number you’re keeping to iD Mobile, @Colbartram.
Nowadays the Google Messages app, by default uses the Google RCS “Chat features” service, which results in Google linking the handset device identity to the initial mobile number.
Another way of resetting the number, used by Google RCS “Chat features”, is as follows:
- Turn OFF RCS chats (“Chat features”) in the Google Messages app.
- Turn OFF the handset and carefully remove the iD SIM card.
- Check the iD SIM card is OK (clean and undamaged)
- Reinsert the iD SIM card.
- Turn ON the handset.
- Turn ON RCS chats
Thanks for the insights andewhite. I wasn't aware I could have left switching the SIM until after iD told me they had done the switch. Indeed, I thought it would mess things up if I hadn't got the SIM installed ready! Hopefully others will find your recommendations about the RCS stuff.
Normally, it wouldn’t matter @Colbartram.
However, Apple’s iMessage service and Google’s Messages app (that uses the Google RCS service), requires linking the handset device identity with mobile number of the SIM card in device.
If the mobile number of any given registered device identity (handset) changes, sometimes Apple / Google don’t detect the number change and incorrectly tag iMessages / RCS messages with the pre-change mobile number.
Hi @Colbartram
Glad to see the above helped, thanks for the tip here @andewhite.
