How do I update a Paramount+ payment method when the TV says the router is not supported?
Answer
When a TV cannot update Paramount+ payment details—or shows a router not supported message—sign in at paramountplus.com on a phone or computer, open Account > Subscription or Billing, and save the new debit or credit card there.
Before you start: stop right away if…
- Avoid lookalike billing sites from ads; type paramountplus.com yourself.
Follow these steps
Open Paramount+ on a phone or computer
On a phone or computer, go to paramountplus.com in a browser and sign in with the account that has the subscription.
You should see: Your Paramount+ account home or profile page loads.
Open Account, then Subscription or Billing
Open your profile or account page, then choose Subscription and Billing, Payment Method, or the closest billing label shown for your account.
You should see: The current plan and payment method details appear.
Enter and save the new card
Add the new debit or credit card, confirm the billing address if asked, and save the payment method.
You should see: The site confirms the new card is saved or that the bill paid successfully.
Restart the TV app and sign in again
On the TV, close Paramount+, reopen it, and sign in with the same account. Ignore router not supported for payment updates if streaming still works after billing is fixed on the web.
You should see: The TV app recognizes the active subscription, or shows a clearer network message unrelated to billing.
Check network help only if video still fails
If the TV still cannot stream and keeps saying the router is not supported, update the TV or streaming-device software and review Paramount+'s supported-device list for that model—billing is already handled on the web.
You should see: You separate a billing fix from a device or network compatibility issue.

Extra tips
What to look for: A router not supported or similar TV network message, missing payment options in the TV app, and Account, Subscription, or Billing on the Paramount+ website.
Before you change anything: Use the same email account that bills Paramount+. Prefer the official paramountplus.com site over random search ads. Have the new debit or credit card ready. Never share the full card number in a public forum or with unexpected callers.
