How crucial is running Android before Sailfish install?
The Post Office tells me that after a long wait my Xperia X will arrive today, and it's my plan to immediately back it up, upgrade Android if necessary over wifi, do the things necessary, and install SFOS on it. In looking at the instructions, I was a little alarmed to find this:
"IMPORTANT – Do not skip this step
"Use your Xperia X some time with Android OS. Check that phone calls can be made and received, that you can browse the Internet with a mobile data connection (turn WLAN off) and that the camera works. You might also want to check the touch display, loudspeaker and microphone.. Use the same SIM card as will be used with Sailfish X."
Is this solely to determine that the phone works, or does something else happen without which Sailfish OS won't properly install? The whole purpose of the exercise, for me, is to avoid running Android with the SIM card installed, so as to minimize the data that are harvested. It is my plan to put in the SIM card only after I've installed SFOS, Yalp (for the ProtonMail application, alas) and set up my VPN. But that gets confounded if I have to go around making calls on Android before I can do any of it.
So how important is "IMPORTANT"?
I'm writing this as a comment rather than an answer because I'm not sure if this info is still valid. But: Back in the days when I installes SFOS on My Xperia X it was important at least to update Android to the latest version. I remember that because it took ages. Only the most recent version of Android for the Xperia supported the easy route of installation recommended by Jolla. If this is still the case you'll have to keep it switched on and "use" it at least on Wifi for a while.

Don't know why, but there can be a problem with some simcards. Other users have same problems, so maybe you should search for this threads and have a look, before running into trouble when not having inserted SIM during initial Anroid startup.
