Can Old Nokia Phone Receive Calls from Unknown Number Without SIM Card? Operator Involvement?

Hello,
I am asking for your opinion on a rather strange issue ...
I use an old Nokia phone as an alarm clock. Somehow it is better in the morning to turn off the alarm clock "by heart" on the button than on the touch display. There is no SIM card in the phone. Three times the phone rang, there was a beep, and the display read that "unknown number" was calling. After picking up, silence in the loudspeaker. The first time, in the middle of the night, my heart almost stopped.

Is such a situation, even hypothetically, that the operator can make a call to such a telephone?

Network operator error or supernatural phenomena rather

There have been many such cases. If the history of the cell is unknown, it is best to get rid of it.

Operator error - it means that the phone, even without a SIM, is trying to "get along" with the nearest transmitters?
I would be rather calm about the origin of the phone - it has always belonged to me.

Yes it can. Without a SIM card, you can make calls to the emergency number.

Not so much trying, but getting along, if only for you to be able to call the emergency number. If possible, turn on airplane mode, then it will be completely disconnected from the network.

You can make calls from any phone without a sim card, but if the phone is without a card and shows an incoming call, it is rather a supernatural phenomenon, as someone wrote earlier.

Perhaps in some spiritistic forum it will be easier to find the answer :D

And seriously, I have not encountered something like this, but I think that theoretically a software / transmitter error is possible.

I also use an old phone as an alarm clock and this has not happened to me yet.
You can observe one interesting thing.
When I was using the phone normally, the battery lasted about 4 to 5 days.
Now, when the phone is an alarm clock, I can't remember the last time I charged it.
So the phone does not lose electricity to connect to the relay, and thus it is impossible to establish any connection.

There are also conspiracy theories on the Internet about eavesdropping on all of us and progressing surveillance, but I don't want to get paranoid.
I have read about strange cases where the phone rang and after answering you could hear the previous conversation. It's hard to say how much truth there is.

The phone rang 3 times throughout the last year so these weren't common incidents. Yesterday I turned on airplane mode as you suggested.
As for the battery, it's true - without a SIM card, you only need to charge the phone once a month.

Of course they eavesdrop and call the unruly ones to remind them, even if the phone has no card.

But it's not that way

They eavesdrop, record and track. I myself had a friend from Germany called and after a while I heard our previous conversation. But without a card, it's probably not, because if you do not have a number, if someone calls you.

They have no reason to eavesdrop on grays like us. Poland is not the USA.

The subscriber's number is in the SIM card with a unique ID, but the IMEI is also unique (its clone is visible in the network as a conflict).
It is this IMEI that allows you to make calls (emergency call).
Is it used in the second? Probably not.

Oh! You'd be surprised! My wife was talking (stationary) with my cousin from Germany and after finishing the conversation, she did not hang up immediately, and thinking that my cousin was talking something else, she listened to the whole ... well! ALMOST the entire conversation. I say "almost" because she only heard the cousin's lines !!!! Her statements seemed to be cut out ... I would like to add that the case took place after an incident (attack?) In Germany, and the cousin works in the industry related to this event.

A lot of truth, because I was shocked myself when I was disconnected from my interlocutor, and after a while the phone called me and I heard the recorded conversation that I had just made.

Another curiosity is my two-time conversation with my friend from Germany via WhatsApp.
During both conversations, someone seemed to be hitting the glass with a spoon every now and then.
The first time I told my friend to stop stirring the tea, he said it wasn't him, that he thought it was me tapping the glass. Immediately after these words, the knocking stopped.
After a few weeks, maybe a month, the story repeated itself, only that I immediately told my friend that the knocking was again and that they were listening to us again, and after these words the knocking stopped.

I once read that there are keywords like Islam, bomb, terrorist etc. followed by automatic recording of the conversation. The US forced it on the EU.
For a drink, I once used the word bomb during two conversations
then I heard a strange crackle in the smartphone's speaker. Or maybe I'm oversensitive

Too many movies, gentlemen

Better to use Signal App.

Or maybe it's notifications set in the calendar?

I don't use a calendar and I don't have any notifications.
This sound is normally like tapping a teaspoon against a glass after mixing the tea.

It happened to me 2-3 times that I received a notification from the network (not a text message) that I should contact a number. And it wasn't about a missed call. Anyone had something similar?
Ps.
A number from another network, of course, none of my friends.

With this calling to a phone without a sim, new phones have such an option, if someone steals you, you can normally locate him via GPS and even call him even though he does not have a sim card.

Modern GSM line wiretapping is not a parallel device connected to a fixed telephone line.
Such "something" is possible, but only in the analog line and was used a dozen or so years ago.
Now, wiretapping is a recording of a data stream and its simultaneous decoding, which makes it possible to hear a conversation, but not to interfere with the conversation.
It would be possible if this stream was interrupted, one of several hundred conversations was isolated according to ID, and your microphone with a spoon tapping against a glass mixed with this conversation and integrated it again with the stream.
It is a bit backbreaking and illogical; the eavesdropper does not want anyone to know that they are eavesdropping.

This phone is not the latest
As I read you, it turns out that some state services would have to deal with all this. As far as I know, the Americans in Germany near Manncheim have their European headquarters for data processing and analysis. I don't know if we have such a center in Poland.

Maybe not, but the mandatory registration of prepaid numbers resulted from the adoption of the anti-terrorist act. As nowadays, you do not need a sim card to make calls, but only a WiFi connection, the "State" probably does not necessarily monitor active phones, even those without a sim card, as they are seen by GSM antennas (unless someone turns on the airplane mode).

Or he will put the phone in a metal tin.

However, it seems to me that ordinary gray citizens are not eavesdropped.
What could they find out interesting?

Besides, how many people would have to listen to it, there are probably millions of calls a day on a national scale.

You would have to ask the guests what they put their BTs or they can connect to the camera only by IMEI.
Probably yes, because the card is only a carrier of the account balance and not the identification of the camera and BTS is actually connected with the IMEI and not with the card.

As for eavesdropping, every conversation and text message are recorded and stored, after all, it's not even secret, everyone knows about it, just like logging into bts.

You have a cell. We know where you've been.

A wiretapping like from movies, i.e. someone with a handset to his ear in the next room or a car on the pavement - this is actually direct surveillance, possible after obtaining a permit for it.
Practical wiretapping is a constant recording of the stream (approx. 9 kbps for one conversation), then (at any time, until it is deleted from the carrier) reading the conversation according to the data: date, time, telephone number.
Where are the sites containing such archives?
Most often in modern buildings without windows (server rooms).

Encrypted conversations (e.g. government telephones) cannot be heard (except for secret services) until they are declassified, and:

the encryption methods used guarantee that even if someone managed to intercept the data stream, its reading will take up to 50 years

That's right. I had such a case myself. My previous phone called me once in a while and you could listen to my wife's conversation for a few minutes. The text was always the same. Not only that, once I lent it to a friend, of course he inserted his SIM card and was very surprised when he called him and the text was the same again. And what do you say?
