Integrate eSIM Provider APIs into Ready-Made iOS & Android App + Stripe Setup

Project Title

eSIM Mobile App Integration (iOS & Android) + API + Payment Setup

Project Description

I have purchased a ready-made mobile app with backend from CodeCanyon.

I also have the eSIM provider APIs.

I need a developer to:

Connect the provider APIs to both iOS and Android apps

Integrate all eSIM packages/products into the app

Ensure packages are dynamically fetched via API (not manual entry)

Set up payment method integration (Stripe)

Connect the app with my existing Shopify website (if required)

Prepare and publish the apps to Apple App Store and Google Play Store
Additional Requirement – App Design

The current app design (purchased from CodeCanyon) is not satisfactory.

I need:

A completely redesigned UI/UX

New modern design prepared in Figma first

Unlimited or reasonable revisions until approved

Clean, professional, telecom/travel-style interface

Final approved design to be fully implemented in both iOS and Android apps

The design must be original and not reused from the existing CodeCanyon template.

Important:

I currently do NOT have Apple Developer and Google Play Developer accounts. I will need guidance on creating and setting them up.

The solution must be fully functional and ready for launch (I want to start advertising immediately after completion).

Clean UI/UX improvements may be required if needed.

Please share:

Your experience with API integrations

Any previous eSIM or telecom-related projects

Estimated timeline

Final fixed price

I am looking for a long-term collaboration if this project goes well.
