\n is the Flutter consumer software solely<\/strong>. It requires the
\n eSimScan \u2014 AI-Powered eSIM & Information Plan Market Script<\/strong>
\n (Laravel 12 + React), offered as a separate CodeCanyon merchandise<\/strong>,
\n which is not a part of this obtain<\/strong>. The app can’t show
\n knowledge or course of an order with out it. That backend already ships the

\n cash.<\/strong> No AI supplier, API key or utilization allowance is included
\n with this merchandise.<\/strong> You provide your individual key and the supplier payments
\n you straight<\/strong> for each request at their present charges. The
\n characteristic is disabled by default<\/strong> \u2014 in the event you by no means configure a key,
\n the advisor reviews that it’s unavailable and the remainder of the app works
\n usually. Different providers you join (eSIM suppliers, Stripe\/PayPal, internet hosting,
\n Apple and Google developer accounts) are likewise billed to your individual accounts
\n and are not included<\/strong> within the buy worth.<\/p>\n
