I will traveling to the US next week - I will stay there for around 30 days - and would need an additional extra minutes bundel for my Dutch KPN mobile phone contract that would allow me to call and sms within the US but also from the US to NL and Germany. I want to purchase the largest available package (e.g. 500 min). I have talked to someone at KPN Klantenservice earlier today. Unfortunately she couldn't answer my question in English. As far as I understood from what she was explaining to me in Dutch,
I would need to text the following message "VOORDEEL 500 AAN" and send it to #1266. Could someone please confirm? However, how would KPN know that I am traveling outside the EU, in my case to the US??? This doesn't make sense to me, unless I would add the location. e.g. US....
I would very much appreciate a reply asap. The answer can also be in Dutch.
