Yes, you can.
When you order a Pin type refill it is always sent to the email address that is chosen when you order.
The pin can be used for any prepaid simcard from the corresponding provider.
You can forward our email with the pin and instructions to somebody else, or, alternatively, you can contact the provider and ask if they could activate the pin manually.
If you order a direct refill, you will have to enter the phone number which has to be recharged, in the field next to the product. We will send you a confirmation email so you know the person you're sending the refill to has received it.
