When it comes to data usage, it is generally recommended to use SIM1 as it supports all the features of the network, including 2G, 3G, and 4G. This means that SIM1 can provide a faster and more reliable data connection compared to SIM2.
SIM2, on the other hand, is usually limited to making or receiving voice calls and may only support 2G network. This means that the data speed and coverage on SIM2 may be slower and less reliable compared to SIM1.
In personal experience, I have found that using SIM1 for data purposes offers a more seamless and efficient browsing experience. Whether it is streaming videos, downloading files, or using data-intensive applications, SIM1 tends to provide a faster and more stable connection.
It is important to note that the actual performance of data on a SIM card can also depend on various factors such as network coverage, signal strength, and the capabilities of the device you are using. However, in general, SIM1 is the preferred choice for data usage.
If you prioritize a reliable and faster data connection, it is recommended to use SIM1 for data purposes as it supports all network features including 2G, 3G, and 4G. SIM2, on the other hand, is typically limited to voice calls and may only support 2G network, resulting in slower and less reliable data connection.
