Dual-SIM
mobile phones are an often overlooked category of handset. Most of us have
enough trouble with just one SIM card – why would we want two? But there are several
good reasons to use dual-SIM mobile phones, and we'll outline three of these
below.
Accessing services while abroad
As
online services like banking become an increasingly essential function ofmobile
phones, there’s an ever greater needfor users to be connected and contactable
wherever they are in the world. This is where dual-SIM mobile phones are indispensable.
Let’s
take the example of online banking and two-step transactionauthorizationthat
requires users to input personal details anda code sent to them by the bank via
SMS.In most cases this wouldn’t be problematic – your phone is usually
conveniently within reach. But in certain scenarios – like when you're
travelling and are using a local SIM card – completing a banking transaction
this way can be cumbersome.
The
easy solution is a dual-SIM mobile phone. This would allow you to access your main
SIM card from your phone, without having to physically slot it in and out of
the handset every time you needed to perform a transaction. At the same time,
you couldalso take advantage of local phone and data ratesvia a second SIM, avoiding
paying expensive roaming charges.
Separation
of phone identities
Dual-SIM
mobile phones are extremely useful for another purpose: separating different
parts of your lifewithout carrying more thanone phone. The clearest advantage
would come from designating one phone number to work matters and another to
personal communication. If both SIM cards are contained in one handset, you can
easily access both profiles as necessaryand – perhaps more importantly – shut
them down when appropriate.
For
example, if you were attending an extended work meeting, a dual-SIM mobile
phone would easily allow you to silence, monitor, or shut off completely calls
and messages to your personal number. Conversely, after work hours, you could block
off work calls easily to concentrate on quality personal time. Withmany
manufacturers (including Lenovo, Samsung, and Nokia) releasing dual-SIM mobile
phones, you only need one handset in your pocket.
Better
networking
Dual-SIM
mobile phones can be useful for another slightly craftier reason. Many mobile
carriers offer preferential rates on certain types of communication
or data usage patterns. The most popular package deal is free calls to other
numbers on the same network – the idea, of course, is to promote loyalty among
customers. With a dual-SIM mobile phone featuring two local SIMs you can double
your amount of free calls to numbers across networks.
Usefully,
dual-SIM mobile phones also mean increased network access. Some cities, for
example, have very uneven network coverage across carriers. The eastern part of
a city may receive a strong signal on Network A, while the western section
might see the same signal weaken to inacceptable levels, favouring Network
B.Having two SIM cards means you can switch to the network with the best
coverage and the strongest signal for your location, quickly and conveniently.
