I´ve just changed networks on my UK international i9300 Samsung Galaxy S3 so I can use a H20 wireless (AT&T network) SIM.
I tried a few different modems via the GetRIL app, but couldn´t get any to match. I then used GalaxSim Unlock to unlock the phone. The IMEI was temporarily removed but I restored the original modem via GetRIL and it appeared to be unlocked still.
I can now dial with the phone but the only difference is the keypad tones fail to work during the call. When dialling, the numbers come up on screen correctly and make the normal keypad tones. The problem is during the call when an automated line will ask for numbers to be input. They will come onscreen but make no noise, so the other end considers I´ve not entered anything.
There are no settings available to alter, I´ve tried a reboot etc. but nothing has helped. Í´ve had a look on Google but I can´t see anyone else who´s had this problem. Any ideas?
P.S. It is possible the RIL/modem works for texts, calls but isn´t quite the right one to produce DTMF dial tones?
