Make sure you are just dialling the number the same as you would at home without adding any dialling codes.

As you are roaming in Slovakia it's unlikely that O2 could do anything as if a fault, it will be on the local network.

I hope it gets resolved ASAP for you, @zsoltk. Tell them what you told us, that it's not just your phone doing it, it's happening to your mum too. To get through to speak to someone at o2, select the lost or stolen option. Please let us know when they get to the bottom of it.

That's the reason unfortunately @zsoltk
Nothing O2 can do about roaming networks
