The Many Uses of a Dual SIM Phone

By now it is likely that you have seen the term “Dual-SIM” before, and may be wondering what that means or why such a thing would exist.

A Dual SIM card phone is a phone with two SIM cards. Each SIM card gives you a phone number and a connection to the phone network. It can hold two numbers and two identities at once. You can make or receive calls and send or receive texts on either number and you can give each number only to the people that you chose. They are mainly popular in locations where lower prices apply to calls between clients of the same provider.

This phone can be particularly useful for users wanting to use two distinct phone numbers whilst only working from one device, or for users with internet data separate from their mobile carrier. Although not all Dual-SIM devices work in the same way, the premise is the same; two SIM card ‘slots’ inside one device.

Why Buy a Dual-SIM?

Here are some of the following reasons why a Dual SIM Phone is ideal to use when you travel:


Convenience

One benefit of the Dual SIM Phone is that it allows the user to have both a personal and business phone number within the same phone, so you would have the convenience of only carrying one phone. Users can place their ‘work’ SIM card in the phone alongside a personal SIM, meaning they only have to carry one handset but have the freedom of a personal and business number.


This can also be particularly useful for those users who have two job or roles, needing two separate phone numbers or travelling and need two separate numbers which will allow them to automatically switch between the two SIMs.


International Tariffs

Another popular use for Dual-SIM is for international network hopping. If you travel quite frequently and need to add a separate cheaper SIM for a particular country, or simply a more internationally friendly tariff (travel SIM), Dual SIM phones allow you to carry both lines in one single phone. This keeps your primary number contactable with the addition of cheaper international costs for use on the go.

 

Data-Packages

Data Packages

If you are a regular internet data user, it may be worth investing in a separate ‘internet data only’ SIM so you don’t unintentionally rack up a sky-high bill on your primary phone bill.

Dual-SIM devices allow users to switch between the two SIM cards depending on the task you’re up to. This means that you can you can switch from your primary phone line to the cheap data card if you fancy a bout of streaming.


Business and pleasure

A Dual-SIM phone is also a great way to carry one device while keeping your personal and work lives separate. You don't have to give your personal phone number to your boss or clients and you can keep your work number out of the hands of telemarketers. Also, when an unknown number shows up on your caller ID, you'll be able to see which line is ringing and get a clue as to what the call is about.


A dual-SIM setup, allows you to use both a temporary, local SIM for data and local calls while keeping your personal SIM from home in your phone for family emergencies, work, or other uses. This means that anyone at home can reach you immediately and cheaply (not vice versa though) and you can chat with local friends without incurring roaming fees. It's convenient, it saves money, and you don't have to carry around two handsets.


If you have a dual SIM phone, then going on vacation is pretty simple, you can just keep your regular SIM card in your phone, and add a local SIM card in that second slot. You will be able to make local calls and texts cheaply using the second SIM, making it cheap to stay in contact with your travel partners and get in touch with local contacts. You’ll also continue to be accessible to your friends and family at home, who can still call or text you without paying for an international call or getting a busy tone.


When overseas, if you pop in a local SIM card and pay the same rates as the local people and when you need to, you can use your main SIM card for those urgent calls back to the motherland.

Battery Life

Extended battery life

Not only does a Dual SIM phone offer you a way of using two SIM cards at once, the chances are that the phone will also have a huge battery life. Most Dual SIM phones are of lower spec and therefore the battery doesn’t need to power processors or huge screens, leaving users with a battery that lasts longer for making important phone calls.


Full network coverage

There may be times when you are abroad and your phone doesn’t pick up any network coverage. But Dual SIM phone allows you to be able to connect to different networks when in a black spot with less fuss.


Make the most from different tariffs

Sometimes it might be cheaper to opt for two tariffs with two separate SIM cards. If that is the case, then owning a Dual SIM phone means you can do everything you want, from one phone.

 

Travel and global roaming

One of the most obvious reasons for multi-SIM devices is for international travel. Roaming charges abroad can run up the bill quite fast and sometimes a local SIM is the only sensible way to stay connected whilst traveling. However, if you put a new Sim into your phone, you become unavailable to all those people back home who have your number. If you are going overseas? A dual-SIM smartphone is an easy way to keep receiving messages from people at home. Purchase a local SIM and pop it in the second tray to avoid nasty international roaming charges when you call people in the country you’re visiting.


Additional features

More often than not, a Dual SIM phone comes with other features that aren’t readily available on smartphones. One such feature is a flashlight. In the middle of the night, when turning on the light is not an option. Also, an integrated-internal radio antenna means listening to the radio is as easy as pressing play. No more plugged in headsets.


Balanced calling plans

Another good use for Dual SIM is to take advantage of imbalanced calling plans. For example, you might use a low-cost PAYG sim for unlimited internet access to supplement your cheap Internet-limited contract that provides good value minutes and texts. You could also use a SIM that has unlimited calls in the evening alongside one that has better rates during the day, to save money.
