If you wipe the device and didn't turn Wifi on, you have the old versions of all factory installed apps. Once you turn on WiFi, all of them will update.

Note that surrogacy is illegal in many countries of Europe (sorry for the German page, I couldn't find the image in English Wikipedia).

Oops, sorry, I misread your question.

Did you check the wiki entry?

If it doesn't matter if it's a few seconds too late or too soon an ATtiny 85 is good. If you need more accuracy you probably need an additional RTC.

Maybe the LOLIN C3 Pico?

So you have these boards already? Or could you just get other boards with an ESP32 and LiPo charger? Because many already have a printed or ceramic antenna built-in.

Is this not the same ESP32 with an antenna? Although I don't know how the nRF52840 from your question comes into play here. Don't you normally use an ESP or an NRF, and not both at the same place (with the exception of a gateway maybe)?

I'm not sure, but I think these USSD/GSM codes still work nowadays.

Maybe you are talking about CGI scripts? With CGI scripts the web server will start a new process for each request. PHP can run as php-cgi, but nowadays mod_php and php-fpm are more common. CGI scripts can also be shell scripts or compiled programs.

So you delete your cookies and then complain that you have to login again and again?
