Hello, i live in Tunisia and due to laws in my country, the negotiations failed with Paypal team. i made an account and i have a friend who lives in Europe who will send me money to purchase things online such as gift cards etc. The question is can i do purchases if my PayPal account isn't linked to a credit card nor a bank account
The option to 'receive' paypal payments is sadly not available in Tunisia. You can only 'send' payments for purchases.
Paypal varies a lot country to country and can only offer the services that the banks / governments of that country allow it to offer. There are quite a few countries unable to receive paypal payments.
