Is using dual SIM harmful?
Since two independent radio circuits in your phone are trying to reach out to cell tower signals, the emf radiation doubles when you use a dual sim phone. When you use only one sim on a dual sim phone, the blank sim is still communicating with the tower.

Is dual SIM better than single?
SIM phone lets you take advantage of the best deals when it comes to carriers. One carrier may have great data rates, while another may have better voice call or bundle deals. You can take advantage of both of these carriers at the same time if you use a dual sim device. For example, if you are on AT&T and you want to use a Verizon SIM card, you can do so.
If you’re on T-Mobile or Sprint, however, they won’t let you do this. The reason for this is that they don’t want you to be able to switch to another carrier and use your old phone number to make a new one. This is why it’s important to know which carrier is best for you.

SIM phones allow users to keep separate contact lists on each SIM, and allow easier roaming by being able to access a foreign network while keeping the existing local card.

Dual-sim phones can also be used to make calls from one country to another. For example, you can make a call from the U.S. to Canada and then from Canada to the United States, or vice-versa.
Can a SIM card affect battery life?
A faulty / dodgy SIM-card could cause increased battery usage if it’s causing the phone to not stay connected to the network as the background processes involved in reading the SIM-card and registering to the network would be running far longer than normal.
If you’re having issues with your phone not connecting to a network, you can check to see if you have a faulty SIM card by going to Settings > About Phone > General > Serial Number. If you don’t see a serial number, then your SIM is faulty and you’ll need to replace it with a new one.
