Finally email support fixed my error with VoIP login on Saturday within hour, very prompt! Tried out the VoIP feature which is for outgoing calls only (no incoming like on old piranha).

It seems that calls not answered get billed for the first minute on VoIP, whereas calls from the SIM card are not getting billed for unanswered calls.

I took my phone out for testing network registration, this works very good. Only problem I can tell is with LTE networks. It seems, even with data switched off on the phone, there is a LTE Ghost traffic of 50kb increments which sometimes get billed and sometimes not. It didn't occur any more when switching to 3G only.

Looking up the apple App Store, there is also a app to handle customer zone on the mobile, it is called noi box.
