How to make the mobile unavailable?

if ur fone is a Sony ericsson, simply enable the flight mode. U can use ur fone everything except making a call and u wont receive any call either.

press this to divert *21*122#

and in order to put it on press #002#

regarsd

Or you can put your phone on silent or vibrate, that way you can see who is calling you.

I know what do you want exactly.

Dial *002# to turn your phone to divert mode .

Dial #002# to cancel

"Divert all calls" or "voice calls only" is the only way u can keep ur network on, while u r in "unavailable" mode, the nbr 122 is used only for Qatar. but flight mode option will turn off ur network (no more communication in & out, either data or voice), u will be only able to listen to music, use calendar, and manage ur files or tasks...

Flight mode works with Sony Ericsson I guess, to do the trick you have to do the following:

1- To Activate the service:

*21*122#

2- To Deactivate the service:

#002#

*21*122# reject all calls even your mobile is swiched on. You will receive an sms stating the number which trying to call you while in this mode.

To cancel this option

#002# Accept all calls.

Or u can try this... (Service from QTEL)

Just type *21*122# and press call from ur mobile...

It will divert all ur calls & u will get a msg immediately if someone try to call u...

(The caller will hear as U R CURRENTLY NOT AVAILABLE)

it can be done on any phone.

just go to "divert all calls" (or something like that)

and divert all ur calls to the number "122"

when anyone calls u it will tell him that ur phone is closed or out of network coverage area, and u will get a message telling u who tried calling u right away...

Do ur PHONE hav FLIGHT MODE option...??

If yes... U can easily switch to this mode and thats it...

The MOBILE will stop receiving NETWORK SIGNALS...

that will depend on your phone model, if your phone have these features check your manual.
