Unfortunately, I am unable to browse the internet and provide you with the most up-to-date information and web sources from this year. However, I can provide you with a general overview of why activating 4G for both SIMs at the same time might not be possible, and provide some arguments and examples to support the explanation.

Why can’t we activate 4G for both SIMs at a time if both the slots are supporting 4G

Answer:
When it comes to using 4G on both SIMs simultaneously, there are a few reasons why it may not be possible or supported by certain devices.

1. Limitations of Hardware: Some smartphones or devices may have a hardware limitation that prevents them from supporting simultaneous 4G connections on both SIMs. This limitation could be due to technical constraints or design choices made by the manufacturer.

2. Antenna Design: Smartphones and devices have a limited number of antennas to support various wireless technologies. In order to achieve simultaneous 4G connections on both SIMs, the device would need to have separate antennas dedicated to each SIM card. However, devices that support dual SIM functionality often have a shared antenna design, which means that only one SIM can connect to 4G at a time.

3. Network Provider Restrictions: In some cases, network providers may restrict the use of 4G on both SIMs simultaneously for various reasons. This could be due to network capacity limitations, network management policies, or to promote their own services and plans.

4. Battery Life and Power Consumption: Using 4G on both SIMs at the same time would significantly increase power consumption and put additional strain on the device’s battery. Most smartphones are optimized to prioritize power efficiency, and enabling simultaneous 4G connections on both SIMs would have a negative impact on battery life.

5. Signal Strength and Quality: Activating 4G on both SIMs at the same time could potentially lead to reduced signal strength and degraded network performance. This is because the device would need to allocate resources to maintaining connections on both SIMs simultaneously, which might result in weaker signals and slower data speeds.

It’s important to note that not all devices or smartphones have these limitations, and some high-end models may support simultaneous 4G connections on both SIMs. However, it ultimately depends on the specific device’s hardware capabilities and the restrictions imposed by network providers.

Additional Questions:

1. Can I use 4G on one SIM and 3G on the other SIM simultaneously
Answer: Yes, it might be possible to use 4G on one SIM and 3G on the other SIM simultaneously, as long as the device supports these network technologies on both slots and the network provider allows it.

2. Are there any smartphones that support simultaneous 4G on both SIMs
Answer: Yes, some smartphones, particularly higher-end models, support simultaneous 4G on both SIMs. However, this feature can vary depending on the device and its specific hardware capabilities.

3. How does dual SIM technology work
Answer: Dual SIM technology allows a device to hold two different SIM cards simultaneously. The device can switch between the SIM cards for calls, messages, and data, depending on the settings and preferences set by the user.

4. Can I use two different network providers on a dual SIM device
Answer: Yes, dual SIM devices allow users to use two different network providers on the same device. This can be useful for having separate personal and work numbers or utilizing different data plans and coverage options.

5. Are there any advantages to using dual SIM devices
Answer: Yes, there are several advantages to using dual SIM devices. They allow users to manage personal and work contacts separately, take advantage of different network coverage and plans, and avoid roaming charges when traveling by using a local SIM card.

6. Can I make calls and use data on one SIM while the other SIM is on standby
Answer: Yes, while one SIM is active for calls or data, the other SIM can be on standby mode. This allows users to receive calls and messages on the inactive SIM, but they cannot use data or make calls from that SIM unless they switch the active SIM.

7. Are there any disadvantages to using dual SIM devices
Answer: Dual SIM devices may have some disadvantages, such as increased power consumption, reduced signal strength in certain scenarios, and potential software complexities in managing two SIM cards. Additionally, not all devices support the same features and functionalities when it comes to dual SIM usage.

8. Can I use both SIMs for 4G if I have two different network providers
Answer: It depends on the device and network providers. Some devices and network providers may allow the use of both SIMs for 4G, while others may have limitations or restrictions in place. It is advisable to check with the device manufacturer and the network providers for specific details and compatibility.
