Cannot make a phone call

Recently more and more often I cannot make a phone call. After selecting the number and sim-card to use, I get the (Dutch) message “Oproep niet verzonden” (“Call not sent”). I am within reach of the network, because I can send SMS’s.

Is this another thing I have to live with? Or can I do something about it?

Help and responses appreciated!

Please have a look into this thread. Current workaround is: wait for about 5 sec before choosing your SIM card to make that call.

I guess your SIM cards are set to “always ask”. You just have to wait about 5 seconds before selecting one of them and it will work.

I have read in another thread about a workaround: Wait 5 seconds before tapping the SIM card.
