Dear all,
I get regular error message when I try to call anybody. Although the internet access is working without problems, calls don’t. So it is not a question of connectivity. People can call my anytime but can’t call them back.
Please help me. I am simply not happy to have a mobile which is only able to use internet.
Thank you in advance!
Do you use two SIM cards in your FP2? If so and if your settings are “always ask”, then you should try the following workaround: wait about 5 sec before choosing the SIM card you wanna make that call with. Also described here.
Thanks for your help!
It is not what I respected from a dual SIM mobile but I can make calls…
Great that it works for you too. 
@ArjenU Please have a look into this thread. This should solve your problem as well.
