Cellular Phone Forum / Manufacturers / Nokia / October 2006Can I stop a mobile from transmitting/receiving …?
I have an old (Nokia 6610i) mobile that I want to give to my son to play some Java games on. Is there a way to stop the phone transmitting / receiving / trying to get on a network? Cheers Simon. PS the mobile is ‘expendable’! > I have an old (Nokia 6610i) mobile that I want to give to my son to play > some Java games on.

If it cannot locate a valid network, it *may* go into power save mode. More likely it'll ramp up the signal (this doesn't bother me) to find a network, running the battery down quicker (this does bother me).

More >likely it'll ramp up the signal (this doesn't bother me) to find a network, >running the battery down quicker (this does bother me). The handset will listen for the available networks. When it finds the home network for its sim card, it will try to register. It will be refused, and it will then give up. It won't retry at higher power: it knows when it is not welcome. If it does not find the home network, it will try the available networks in turn, trying to roam. Once rejected by each, it will remember than and not try that network again. It's almost certain to have done that months or years earlier, so it will know not to even try.

Not sure if I got this comment but this phone (as it does not support "off-line mode", would always be able to dial emergency calls if on and should not be given for small kids who don't understand this. OK if the guy is old enough. If given for a kid, at least one should take the phone antenna off, preferably short circuit the receiver (receiver is sufficient and safer but transmitter would be additional safety). All emergency calls get recorded, they know the phone IMEI, can use some of the SIM info (if SIM present) and may find you and you may even need to pay for the trouble caused for the emergency authorities. I would take it seriously! >>> >> I have an old (Nokia 6610i) mobile that I want to give to my son to >>> >> play [quoted text clipped - 32 lines] > > I would take it seriously!

No UK network would accept an emergency call. To be accurate, the phone would attempt to call the emergency number but it would never get connected (in UK) and then only marginally bothers the network, not at all the emergency centre.

I'd let the OP decide if this is sufficient for his/her kid, or if the kid should get a playstation or something else. Taking into account that the local networks would not support emergency calls for a phone without a valid SIM, it would be quite OK to use it without a SIM or with an invalid SIM (an invalid SIM would cause some signalling towards the network at each switch on, but this would be reasonable). Note that if you disable the receiver, the phone would never transmit anything. It will only transmit if it finds appropriate network info but could not do this if the receiver was disabled. However, the phone would consume less power if it can find a network and stay tuned on that, even if was there only for emergency calls (the phone does not know that the local network does not accept emergency calls and would still try to stay tuned on a cell where an emergency call attempt was possible). eagerb@gmail.com declared for all the world to hear... > I have an old (Nokia 6610i) mobile that I want to give to my son to play > some Java games on.

This thread has so many misconception's regarding how to stop the phone transmitting it is beyond belief! Unless it has an OFF LINE or FLIGHT mode the phone will continue to attempt to connect to a network, therefore TRANSMIT. Even if an inactive SIM is refused access to it's original network it will continue trying to register! Removing an antenna will NOT stop the phone from transmitting! It will actually increase power in attempt to connect to a network, it may not radiate the signal very well but it will still transmit. Sure 999, 112, 911 or any other Emergency number may be rejected by UK carriers but the phone still attempts to make such calls and therefore is transmitting. I certainly would not want a child playing with a mobile phone that is transmitting any signal at or above 900MHz, sure the jury is still out on the potential dangers but are you prepared to take that risk? The best option in my opinion is find an alternative *toy* for the child to play with. -- The views I present are that of my own and NOT of any organisation I may belong to. 73 de Simon, VK3XEM. <http://web.acma.gov.au/pls/radcom/client_search.client_lookup?pCLIENT_NO=157452> >> I have an old (Nokia 6610i) mobile that I want to give to my son to play >> some Java games on.

It would never increase its output power after a failure. And the phone would never even attempt to transmit anything before it has all the necessary system information from the network. Assuming its receiver is disabled (removing the antenna is not sufficient for that, close to the base the phone could still get the signal, I was talking about disabling the receiver, short circuit the receiver input or something similar), the phone would never transmit (on GSM). I leave it to each person to judge if the short signalling related transmission for an emergency call attempt has health issues for a child, the fact in the UK case is that there would not be a call, just a few messages sent on the signalling channel. The same at power on, once. This anyway is marginal compared to all the rest of the RF exposure at home or anywhere else. >Unless it has an OFF LINE or FLIGHT mode the phone will continue to >attempt to connect to a network, therefore TRANSMIT. If the handset has a sim card in it, it will transmit for a very brief time in an attempt to register. If refused because the sim ins no longer active, it will stop trying. It will possibly try each of the other available networks, but only once each,. >Even if an >inactive SIM is refused access to it's original network it will continue >trying to register! That's not correct, as far as I know. It would only retry if it had failed to get a response from the network. Once the network has said "No" it won't try again. So we are talking about a few milliseconds shortly after it is switched on. After that it won't transmit at all, unless someone tried to make an emergency call, when it would try each network once more before failing and giving up.

My Nokia N73 is sitting in it's car kit at present with a SIM that is no longer active on the network and it is regularly attempting to register. -- The views I present are that of my own and NOT of any organisation I may belong to. 73 de Simon, VK3XEM. <http://web.acma.gov.au/pls/radcom/client_search.client_lookup?pCLIENT_NO=157452> > My Nokia N73 is sitting in it's car kit at present with a SIM that is no > longer active on the network and it is regularly attempting to register. [quoted text clipped - 4 lines] > > 73 de Simon, VK3XEM. This is an interesting observation. I assume this is SIM card is for one of the local networks. The home network should normally reply with a reject cause that forces the mobile to abandon all future attempts until the phone is switched off. If other local networks don't provide roaming to the home operators of this SIM card, they should reply with a "forbidden PLMN" which info is stored to the SIM and as somebody previously mentioned, the phone should not make even a single attempt to register to those networks, not even after power off/on cycle. The phone could always be faulty but otherwise this behaviour could appear if the network responded with a location area reject. This would force the mobile from further registration attempts until the location area changes. The location area can change when the mobile is stationary (at a location area border) but normally one would need to travel through a number of cells. Would be interesting to know more accurately what "regularly" in your case means. Is it a clear period (approximate time for that) or is it related to moving across location area borders? Some phones have an engineer mode too, would be interesting to see the reject cause values from the network in your case. |
