Anyone with same issue, please report with the following info. We need to have enough info if we want Sony to get any investigation started.
Please indicate if you have already exhausted the "maybe solution" mentioned in this post and if any of those fix your problem.

Yes, i've tried SIMs from different operators.
For the account reset by Singtel, that was the first thing they did before they changed my SIM card the first time round.
As for location-wise, it seems to happen everywhere and anytime, home; work; parks; roofs, even when i was using the phone. Just this morning when i was walking to the bus-stop while using an app to find the bus timings(which works perfectly on all my past Sony phones), it loads for the first ~15s then the signal just dissappears in an instant, like i literally blinked and it was gone then i had to restart my phone.

i would approach Sony Customer Service again and get them look into your issue again.
You swap a new unit, you reset your account with the operator, issue is not limited to a particular location/area..... its really challenging to identify the cause and only the manufacturer has the expertise and tools to find out what exactly cause the problem. Go to Sony again.
I have no more suggestion to offer. Sorry!

Sigh.. On the 4th repair, before they put in the request to replace the phone, they said their engineers couldn't find any faults thou...
But I will try asking again. Thanks for your assistance anyway!

Experiencing this as well. Sudden empty of phone signal. You're only choice was to restart the phone. No issues with wifi or other else, only this network signal. My xz1 is only about a month old. Havent try other operator or other simcard. Im using singtel. Im a sony fan since ericson. So i guess i just have to cope with it, restarting the unit everytime this happen.

I have the same issue dated 2019 06 11 with Singapore Singtel. After changing a new Singtel SIM card, the result is still the same. This does also happen to Singapore M1 sim however Z5 will request restart due to an operator like to optimizes the settings. Both signal strength is very low as the picture showed.
