I got into trap with winsim as they have go offers. I had an international calling app and somehow it didnot work when i moved to different country in European union. Got a huge bill of 1300+ euros from Winsim. I have activated warning message for 150 Eur but i didnot receive any warning message after 150 eur. some operators help their customers by upgrading pack. But i didnot get any help from Winsim. Monthly charges are very less but additional charges are hell.
