Is this official top-up?
+
We use discounted official iOS subscription APIs, 100% genuine.
Will the card code expire?
+
The card code is only invalid after a successful top-up.
Do I need to log in?
+
No. Only your Token is needed, no account/password involved.
What if the top-up fails?
+
Rarely, a failure can occur due to network. If so, check if you have a subscription; if not, just retry.
