Honor Phone Game Disconnections: Deep Dive into Dual SIM Interference and Solutions

Honor phone users have recently reported frequent game disconnections. On January 23rd, Honor's official product maintenance account, @CommunicationLaoYang, released a detailed analysis report, identifying "dual SIM interference" (or "secondary SIM card preemption") as a significant contributing factor and providing corresponding solutions. This article will delve deeper into the mechanism of dual SIM interference, its manifestations in different scenarios, and the countermeasures offered by Honor.

I. Dual SIM Modes and the Definition of Secondary SIM Interference

Understanding dual SIM interference requires understanding the two types of dual SIM modes: Dual SIM Dual Active (DSDA) and Dual SIM Dual Standby (DSDS).

• Dual SIM Dual Active (DSDA): Both SIM cards can simultaneously make calls and transmit data. While one card is making a call, the other can simultaneously access the internet and receive calls and text messages. DSDA requires two conditions: 1. HD voice calling is enabled on both SIM cards; 2. Both SIM cards are registered on network types and frequency bands supported by DSDA (some Honor phones support 5G+5G or 5G+4G combinations for the primary and secondary SIMs; please contact Honor hotline 95030 for specific device compatibility).

• Dual SIM Dual Standby (DSDS): Only one SIM card can make calls or transmit data at a time. When one card is making a call, the other cannot access the internet or receive calls and text messages. In DSDS mode, both SIM cards share a single set of radio frequency resources. When the secondary SIM card makes a call, sends/receives SMS/MMS, switches network modes, performs Location Area Update (TAU), switches cells, loses network connection, or searches for a network, it will preempt radio frequency resources, causing the primary SIM card's mobile data to be interrupted this is "secondary SIM interference" or "dual SIM interference".

II. Scenario Analysis of Game Disconnections Caused by Secondary SIM Interference

Secondary SIM interference can lead to various game disconnections. Honor has summarized several common scenarios:

• Game disconnection caused by a secondary SIM call: When the secondary SIM makes a call, the radio frequency resources are fully occupied, preventing the primary SIM from accessing the internet, resulting in game disconnections. To address this, Honor phones feature an "Intelligent Network Switching Card" function. When enabled, mobile data automatically switches to the secondary SIM during a secondary SIM HD VOLTE call, ensuring continued network gaming during the call. This function can be enabled via: Settings > Mobile Network > SIM Card Management, and toggling the "Intelligent Network Switching Card" switch.

• Game disconnection caused by secondary SIM anomalies: If the secondary SIM is an unusable international SIM card, or if frequent network registration failures occur due to SIM card arrears, aging, or damage, the secondary SIM will frequently preempt resources, causing game disconnections and increased device power consumption. In this case, contact your carrier or use the phone's built-in "Device Detection" -> "Communication and Network" function for preliminary troubleshooting. If a problem with the secondary SIM is confirmed, disable it or remove it from Settings > Mobile Network > SIM Card Management.

• Game disconnection caused by a challenging network environment: When the secondary SIM carrier's network signal is weak or the device is in a network transition area, the secondary SIM may frequently search for a network or switch modes (e.g., 4G/5G switching), frequently preempting resources and causing game disconnections. In response, Honor phones implement optimizations: suppressing the secondary SIM from staying on the 5G network to reduce preemption frequency and shortening the preemption duration in DSDS mode (DSDS timer) to improve gaming experience.

• Game disconnection caused by dual SIM switching: After switching the default mobile data SIM (e.g., from SIM 1 to SIM 2), the game server may continue sending data packets to SIM 1, causing SIM 1 to frequently preempt radio frequency resources and disrupting the game on the currently active SIM 2. Honor has implemented solutions to reduce data packets sent to the secondary SIM by the game server and promises continuous optimization of this issue.

III. Honor's Provided Solutions and Suggestions

To address game disconnections caused by secondary SIM interference, Honor offers the following solutions and suggestions:

1. Enable the Intelligent Network Switching Card function: This prevents game disconnections by automatically switching the data SIM during secondary SIM calls.

2. Check the secondary SIM card status: Check for arrears, aging, or damage on the secondary SIM card; contact your carrier or replace the SIM card if necessary.

3. Disable or remove the secondary SIM card: Temporarily disable or remove the secondary SIM card if a problem is confirmed to solve game disconnections.

4. Maintain a good network environment: Avoid gaming in areas with weak network signals.

5. Keep the system updated: Update your phone's system regularly to receive the latest optimizations and bug fixes.

IV. Conclusion

Honor has conducted an in-depth analysis of game disconnections, identifying "secondary SIM interference" as a key cause. By understanding dual SIM operating mechanisms and the various scenarios that can lead to game disconnections, users can better understand how to solve the problem. Honor's solutions, such as the Intelligent Network Switching Card function and system-level optimizations, aim to improve user gaming experience and reduce disconnections. Users should choose solutions appropriate to their situation and actively cooperate with Honor's ongoing optimization efforts to collectively improve the gaming experience. Continuously monitoring Honor's announcements and updates will provide timely information on the latest solutions and improvements.
