activating sim card

[2088bob]

Hello Everyone

I am leaving for Germany in 5 weeks I have acquired a unlocked dual sim card smart phone to use while I am there My sister lives in Konstanz Germany she is going to buy me an alditalk prepaid sim card deal she is going to send it to me here in Canada My question pretty straight forward can I activate card from my laptop here I will give my sister's home address

Does anybody know why this would not work or should I let my sister activate it there in one of her phones and then send it i would like to have phone service as soon as i hit the tarmac in Frankfurt

thanks in advance for your replies
