       I use a Pixel 7a, which I think is a great phone. Does everything I want it to (but a bit better battery would be nice). I have one odd problem, wondering if it's just mine, or a common issue.I have a standard SIM and an eSIM, they are on different networks (Aldi/Telstra & Amaysim/Optus). Every so often, for no apparent reason, both lose mobile connectivity. Sometimes there might be weeks between it and sometimes it happens several times within an hour. I get the no signal with an exclamation mark on both. Generally, all that's required to rectify is to activate flight mode for 60s then deactivate and both SIMs come back online. Sometimes it needs me to restart my phone.Does anyone else have similar issues? Is there a fix?

       @the_rail_life That's the phone overheating and going into self protection mode where it shuts power off to some components (the radio portion) to reduce power (and therefore temperature).  Well known issue on Pixel phones (causes by an issue on the nexus series, where they got so hot the circuits around the CPU cracked due to thermal changes, bricking the phone).

       @MrAndrewD Interesting. The phone's rarely hot to touch, but I suppose that doesn't necessarily reflect what's happening inside Thanks for the info!

       @the_rail_life @MrAndrewD In areas where reception is poor, you will often notice a typical mobile phone getting very hot, as the RF amplifier raises its gain to maximum. More sophisticated phones may incorporate circuitry to stop this temperature rise, which can cause catastrophic battery failure if you're very unlucky.

       @publius @MrAndrewD Makes sense to switch off the cellular part in that case. Now I know it's to protect the phone, it makes it much less annoying!
