Pixel 9A issues

Located in Australia.

Have had a 9A for about 3 weeks now. Changed from an OPPO because the OPPO didn't support ASHA (advanced Streaming for Hearing Aids).

So far the experience has been pretty favourable, EXCEPT it keeps dropping its mobile network connection(s).

I've tried resetting the connection through Settings multiple times to no avail.

I am now having to reboot the phone every couple of hours. I have dual SIMs (one eSIM and one regularly micro card) on different providers (Telstra and Optus).

The phone just randomly (and regularly) drops one or both networks and needs to be rebooted to reconnect (and going to Aeroplane Mode and back doesn't work).

Because its random its very difficult to convince the shop there and issue, even though a search of the Net indicates Pixels have had this problem since at least the Pixel 6.

Has anyone else had this problem? If so, is there a fix?

Cheers!
