Dear russian fellows..

[SG1_Lud]

Here is how I passed the security check:

Noted down the price of the sim in $ : 14.41 usd
Continued all the proccess of buying with credit card.
Noted down the final price charged in euros: 10.63 euros

Calculated the exchange rate used: 14.41/10.63 = 1.3555

Took the security amount charged (1,06 euros) multiplied by the exchabge rate calculated before: 1,06 x 1.3555 = 1.4363

Rounded up to 1.44 and success.

Important to use a dot as decimal separator (instead of a comma)

Good luck!
