In recent years, many smartphone users have opted for dual SIM phones, which allow them to have two phone numbers on a single device. These phones display the network operator and signal strength for both numbers on the screen. However, when entering a workplace equipped with signal blockers, it raises the question of whether these blockers affect dual SIM phones in the same way. Do they completely block both SIM cards simultaneously, or do they have different effects on each card?
To address this question, we need to consider several scenarios. The first scenario involves two SIM cards belonging to the same network operator, with both cards registered to the same base station. In this case, the signal strength received by both phone numbers on the device is almost identical. As the phone approaches the signal blocker, the blocking effect is consistent. Eventually, both phone numbers will experience a gradual weakening of the signal until they are completely blocked and lose network connectivity.

The second scenario occurs when both SIM cards belong to the same network operator, but they register to different base stations due to a high number of surrounding users and numerous base stations. In this situation, the signal strength of the two phone numbers will differ. As the phone approaches the signal blocker, the blocking effect will vary. It is possible for one phone number to lose signal while the other remains functional, allowing communication to continue.
The third scenario involves two SIM cards belonging to different network operators. Since each operator has its own base station network, the two SIM cards will register to different base stations. Factors such as distance from the base station, transmission power, antenna height, and angle can significantly affect the signal strength received by the phone user. As a result, when a dual SIM phone approaches a signal blocker, the blocking effect on the two different network operator phone numbers will vary. Detailed testing and comparison may reveal that the actual blocking distance differs for phone numbers belonging to different network operators within the same signal blocker environment. This difference in blocking distance can vary depending on the surrounding base stations, with the key factor being the proximity of these stations.
In conclusion, the impact of signal blockers on dual SIM phones depends on various factors, including the network operator and the proximity of base stations. In scenarios where both SIM cards belong to the same network operator and register to the same base station, the blocking effect is consistent for both phone numbers. However, when the SIM cards belong to different network operators or register to different base stations, the blocking effect can differ. Detailed testing and comparison can provide insights into the varying blocking distances for phone numbers belonging to different network operators within the same signal blocker environment. Ultimately, the extent of this variation depends on the proximity of surrounding base stations.
