For example, you can replace the word SIM 1 with mobile number or office and the SIM 2 with the mobile number or personal, as per your likeness.
That’s when it is a good idea to change the name of a SIM card. But even after all that you might get confused about which number you got a call. Sometimes, you can even get the name of your network, for example, Vodafone or Airtel for each SIM card which can also be useful. Today, most Android smartphones come with two different colours for each SIM card for easier understanding, or the name SIM 1 and SIM 2 to help us understand about the number on which we got a missed call at the time of making a call. Depending upon on which number we got a missed call, we can make an assumption on whom the caller might be, and make some appropriate decisions. Whatever the case may be, we can easily differentiate between the two numbers, at the time of making a call or at times when we get a missed call on our mobile. While, there are even some people who have two mobile numbers one for the purpose of calling and sending messages, while the other is for accessing the internet at an affordable price. Most people today use two mobile numbers one for personal usage and others for official work.
