With JoinBareng's shared plan, a standard ITVX Premium subscription from ITV plc can be enjoyed at a lower per-slot cost. Currently the 1-user (private) package is open for members wanting exclusive access, while the group package will follow. You pay via QRIS and receive shared account credentials as per your package.
Once the group package is open, the flow is: choose a package, pay via QRIS, wait until the group slots are filled, then the admin activates the account and sends the access. Credentials are shared account logins, not invitations to a personal email, so do not change the password/email or log out other devices so as not to disturb other members. All group members share one account with shared profile or history.
If you prefer a personal account, consider the ITVX Premium Pay-Service option at JoinBareng. The account remains yours, our team provides the UK billing method, and you pay in Rupiah as usual. For shared plans, the most up-to-date info on pricing and slot availability is on the package card on the product page.
