Yes progx.ch is already 10 years old! To celebrate this the site has become a new version and now offers a responsive web design interface so that you can consult the rates from your smartphone and tablet.
The web technology has changed (passing from php to webdev) and offers a country view, a list of clones and of course the comparator.
The notifications (alerts) of price change will be available soon (by e-mail but also by notifications for smartphone and messages telegram).
Your suggestions, comments, encouragement, error reporting and other messages are always welcome by visiting this link!
We hope that this new version will please you and save you money on your VoIP phone calls!
Happy Birthday progx.ch!
