Whoever has a friend has...

There's no limit! You can invite as many friends as you want, and you'll receive 1 credit for each one when they top up with doctorSIM.

1 credit equals 1 EURO, or approximately 1.14 USD. We will show you the amount in your currency when you top up.

Once you have registered with doctorSIM, simply log in to your account by clicking here and go to "My credits." There you will be able to see all the credits you have accumulated in your account.

You can spend your accumulated credits on any purchase you make at doctorSIM, for any of the services we offer: top-ups, unlocking, and checks.

For our top-up service, you can deduct up to 1 credit per purchase, but if you use them to unlock a mobile phone or to check it, you can redeem as many credits as you want in a single purchase.

If you have enough credits, your purchase can be completely free!

It depends on the service you want to redeem your credits for: If you are redeeming your credits for a balance top-up, the discount will be applied automatically and you won't have to do anything. Just make sure you are logged in to "My Account" before topping up so that we can apply the discount.

If you are going to redeem your credits for another doctorSIM service (unlocking or check), you will have the option to pay by card, PayPal, transfer, or credits.

If you have not accumulated enough credits to make the full payment, don't worry, we will deduct the credits from the purchase price.

Again, make sure you are logged into "My Account" before making your purchase so that we can apply the discount.
