I have a mobile phone with a dual-sim slot and I inserted a SIM in each of them.One of the SIMs get logged in in national roaming which is ok as there is a cooperation between my native service provider and the "foreign" one. I use a separate app (Roaming Control) to handle roaming correctly.
If now I am logged in in the foreign net and I call out to anybody I get a message, to confirm using roaming and not the secondary SIM which is in its native net:
The SIM card that you are about to use is now in roaming. Would you like to continue?
I have to confirm manually which is no problem as long as I have the phone in my hands.
If I am sitting in my car and I use a voice dialer this is nasty: The call does wait for the entry of my decision but does not show the question as the display is in general turned off beforehand. Thus I have to wait for the ring tone and if it is not coming I have to take the phone in my hands (!) and confirm the roaming.
Is there a way to disable this warning?
