How much traffic should you buy?
Choose traffic based on actual usage: browsing uses little, video and app downloads use much more, and multiple devices share the same quota when the provider counts traffic at the account level.

Plan sizing, renewal, traffic reset, device limits and support boundaries for subscription services used with Clash clients.
Accounts, Plans & Traffic Issues
Troubleshoot plan choice, renewals, traffic usage, device limits, unavailable regions and provider-side account status before blaming the client.
When does plan traffic reset?
Traffic reset time is controlled by the provider plan. It may reset monthly, by billing cycle, or by a custom package rule, so check the dashboard rather than the Clash client.
Read answerWhy is traffic consumed too quickly?
Traffic can be consumed quickly by video, cloud sync, app updates, multiple devices, Global mode or background apps routed through TUN. Check the provider dashboard and local traffic view together.
Read answerHow do plan status and traffic usage affect the subscription?
Common symptoms include incomplete subscription updates, node list sync prompts, all nodes need reviewing to connect, or provider status message pages.
Read answerWhat if you do not see a subscription URL after purchase?
If no subscription URL appears after purchase, check the provider dashboard, order status, email, spam folder and support page. Clash clients do not generate subscription URLs.
Read answerCan one subscription be used on multiple devices?
It depends on the provider plan, concurrent device limits, connection limits and traffic rules. Multiple devices usually share the same quota.
Read answerWhat happens when the device limit is exceeded?
When the device limit is exceeded, the provider may reject profile updates, disable nodes or disconnect older sessions. Check the provider dashboard before reinstalling the client.
Read answerDo you need to re-import after renewal?
After renewal, update the existing profile first. Re-import only if the provider issues a new subscription URL or the old URL continues to return expired status after refresh.
Read answerDo you need to reconfigure Clash after changing providers?
Changing providers usually means importing a new subscription URL and refreshing proxy groups. You do not need to reinstall the client, but custom local edits may need to be moved into the new profile carefully.
Read answerWhich issues should be handled by the provider?
Provider support should handle expired plans, missing nodes, 401/403 subscription status messages, region outages and traffic accounting. Client-side issues such as local permissions, ports and YAML edits should be checked locally first.
