Hi,
I am unable to place any calls to an international number (just tried calling a swiss number several times), even when using the correct prefix (in this case +41). What should I do?

If you're PAYG you will need additional credit.
If on contract, you may have a spend cap Guide: Spend Caps & Charge to Mobile on O2
If you can use WhatsApp with the person you are calling, you can do so for free over wifi.
