Message
Internal error.
Description
Internal error.
Possible causes
System processing error. For example, the internal state machine is faulty, or the internal message queue is congested.
Solution
Call the API later.
Message
System service error.
Description
System processing error. For example, IPC fails or the network management service fails to be started.
Possible causes
IPC error.
Solution
Call the API later.
Message
Multi-path capability is disabled.
Description
Multi-network concurrency is not enabled.
Possible causes
The network acceleration is turned off, or the airplane mode is turned on.
Solution
Check whether the network acceleration is turned off or the airplane mode is turned on. To check the network acceleration setting, go to Settings > Mobile network > Network acceleration > Data boost. If this option is not available, your device or its system version does not support multi-network concurrency.
Message
Multi-path links are already active or in the process of being established.
Description
Multi-network concurrency has been activated or is being activated.
Possible causes
Multi-network concurrency has been activated or is being activated, and cannot be activated again.
Solution
Register the multi-network concurrency status change API to learn about the multi-network concurrency information.
Message
App request limit reached.
Description
The number of multi-network concurrency requests has reached the upper limit.
Possible causes
The number of multi-network concurrency requests that can be sent in a day is limited. An error is reported once the upper limit is reached.
Solution
Multi-network concurrency requests cannot be initiated currently. Try again 24 hours later.
Message
Request denied due to power consumption restrictions.
Description
Multi-network concurrency cannot be initiated due to power consumption restrictions.
Possible causes
In power-sensitive scenarios, when the device is overheated, or under any other conditions where power consumption is deemed inappropriate, multi-network concurrency is not allowed.
Solution
Request multi-network concurrency later.
Message
No quota.
Description
The quota is exhausted.
Possible causes
The multi-network concurrency quota (session count or duration) specified for the app or device is used up.
Solution
Multi-network concurrency requests cannot be initiated currently due to quota exhaustion. Try again 24 hours later.
Message
Conflict.
Description
A multi-network concurrency request conflict occurs.
Possible causes
The app cannot request multi-network concurrency currently because the device determines that another higher-priority service is currently using it.
Solution
Request multi-network concurrency later.
Message
Requests are too frequent.
Description
Multi-network concurrency is initiated too frequently.
Possible causes
The app requests multi-network concurrency multiple times in a short period of time or starts multi-network concurrency again promptly after releasing it. This will impact the device or network connection.
Solution
Check whether multiple multi-network concurrency requests are initiated in a short period of time or multi-network concurrency is started again promptly after it is released. If so, ensure compliance with the principle of minimizing multi-network concurrency usage.
Message
No suitable path.
Description
No path other than the current connected path is available for multi-network concurrency.
Possible causes
The requested path does not exist, the path signal is poor, the data switch is not turned on, or the smart data switch function is not enabled.
Solution
Check whether the signal is poor and ensure that the data switch is turned on.
Message
Insufficient traffic.
Description
The data traffic quota of the device is insufficient.
Possible causes
Multi-network concurrency consumes data traffic. It is not allowed if the data traffic quota is insufficient according to the traffic management settings of the device.
Solution
Check whether the device is experiencing insufficient data traffic. If the secondary SIM card is expected to be used, enable the unlimited data switch for it.
Message
Concurrency is not allowed.
Description
Multi-network concurrency is not supported.
Possible causes
The device determines that multi-network concurrency is not supported currently. For example, dual-SIM dual-active (DSDA) is not supported under the current network conditions, or the device does not support multi-network concurrency in dual-SIM scenarios due to hardware restrictions.
Solution
Try again later or change a device for testing.
Message
Release request mismatch.
Description
Multi-network concurrency release information mismatch.
Possible causes
Multi-network concurrency is initiated by an app different from the one that sends the release request. Ensure that the release request is sent by the same app that initiated multi-network concurrency.
Solution
Check whether it was your app that initiated the multi-network concurrency and whether the initiation was successful.
