iPhone in App purchase : Working but Not

I have added in App p开发者_高级运维urchase functionality within my application. We have tested it successfully on iPhone (in sandbox mode). After successfully testing, we sent the application for final testing to tester situated at other country.

In strange case, the tester is not able to test in App purchase functionality. He is getting "Invalid Product Id" error. We are giving same build to tester which is working perfectly at our side. The whole application is working perfectly except in app purchase functionality.

If any guesses.

Thanks, Vimal Jain.

To save you the pain of exhaustively searching the web for the cause of your error, here is a checklist of everything I have stumbled across that can cause an invalid product ID. Make sure you can answer “Yes” to each of these questions:

* Have you enabled In-App Purchases for your App ID?
* Have you checked Cleared for Sale for your product?
* Have you submitted (and optionally rejected) your application binary?
* Does your project’s .plist Bundle ID match your App ID?
* Have you generated and installed a new provisioning profile for the new App ID?
* Have you configured your project to code sign using this new provisioning profile?
* Are you building for iPhone OS 3.0 or above?
* Are you using the full product ID when when making an SKProductRequest?
* Have you waited several hours since adding your product to iTunes Connect?
* Are your bank details active on iTunes Connect? (via Mark)
* Check that your device is not Jailbroken

If you answered “No” to any one of these questions, there’s your problem.
