Can't you use something like paypal or in worst case Bitcoin ?

I'm sure you can send $$$ from Iran to other places. You just have to find some SeDiv re-seller.

SeDiv is software only. License locked to your PC. All transactions are done on-line and you don't need to have hardware shipped to you .... As long as you can send $$$ on-line you should be able to buy SeDiv ...

please send sediv reseller and price in pm thanks
