Title: LAMW USSD code support [SOLVED]
Post by: Segator on July 14, 2020, 04:16:36 pm

Thanks a lot for the LAMW project, its posible to request USSD code using the jTelephonyManager or other componet?, USSD is like a call but is for special things with the phone company or internal command, an example is *222# but is i try it with jTelephonyManager hi try to call to *222, miss the # char.

I did some investigation on this some time ago, and only since some recent changes from Google there wasnt a reliable way of doing this, this method worked on some devices:

Now for Oreo and up there is:
https://developer.android.com/reference/android/telephony/TelephonyManager.UssdResponseCallback

I dont think it will work LAMW but maybe someone with more knowleage can confirm it.

it's ok if the USSD dialog must show for older phones, can you add normal USSD request for all phones and the hide dialog for recents moviles?

Thanks for the replys.
