Dual-Subscriber Identification Module (SIM) phones let you use two SIMs in a single phone. With more people cutting the cord from their landline phones, a dual-SIM phone is a great way to separate your personal and business lines.
If you have multiple businesses, it is another way to differentiate them when you are outside of the office. After all, juggling multiple handsets can be taxing. Most dual SIM phones have active dual SIM functionality. A dual SIM phone can support two active SIMs at the same time, without requiring you to remove and swap SIMs to change the phone number.
Advantages of Using Dual SIM Phones
There are many advantages to using dual SIM phones, not the least of which is the ability to manage business and personal calls on the same phone without using second phone number apps .

Think of it as being similar to separating your work and personal e-mails.
For freelancers too, a dual SIM phone can come in handy as you can handle multiple jobs without having to juggle multiple devices.
Functionality aside a dual SIM phone comes in handy for saving on your phone bill. Say you have grown attached to your old SIM and you want to capitalize on a new data offering from a SIM card. Some mobile operators have good voice plans, but pricey data plans, or the other way around. Irrespective of the same network or a different network you can use the data on one and use texts and calls on the other. All this without the need to change your number or invest in another phone.
A dual SIM phone also comes in handy if you travel abroad for business or a vacation. With room for another SIM card, you can buy a temporary card and avoid international roaming costs. You can buy a 30-day SIM, not have to buy another phone and retain your contacts from the same handset.
