hi,

I would like to know is that possible to get the mobile phone number of the handset using J2ME?

I could recuperate the subscriber ID. is there a possibilty to link the subscriber ID and the phone number.

If it is not possible in J2Me, can it been done in other ways?

Thank you

OULD NADIF

I have heard that when you make a HTTP connection through the carrier's proxy, the carrier might insert the phone number in the HTTP header. If this is true, you can have a servlet that bounces the phone number back to the MIDlet. Does anyone know whether this is workable? Thanks.

Some carriers insert the MSISDN (phone number) into a HTTP header, but there are several but's, including:
  • Not all operators do this (some won't publish the MSISDN at all to the service provider, some publish a "session ID" which they themselves can map to the MSISDN but which is useless for the service provider)
  • Every operator uses a different header name (most just use the default MSISDN header of their selected gateway product but every product has a different default...)
  • Some carriers require you to pre-register the URLs to which their gateway adds the MSISDN header

    Thanks, Lasse. Well, we have to wait for phone makers to implement JSR 177 to get MSISDN locally from the SIM card then!

    Hi all,

    Thanks a lot for your help.
    Waiting the JSR 177, my application has to ask the user to enter his own phone number.

    Yes but even if you can access the SIM card, there is no guarantee the MSISDN is on the card or is accurate (it can be set from software on phone)

    The network is the best bet, via the http method mentioned, OR via sending an SMS from the phone to your server via JSR 120. The MSISDN is always resolved on an SMS.
