What is Dual Sim Card?

 

A dual sim card, very often also called a dual sim adapter or dual sim adapter card, is a holder for sim cards enabling to have a phone equipped with 2 sim cards at the same time.

There are several kinds of dual sim cards available. They can be distinguished as Cut Dual Sim Cards and No Cut Dual Sim Cards.

The Cut Dual Sim Card is the older version with Hypercard 3G being one of the most popular Cut Dual Sim Cards on the market still today and also being the first fully 3G and 4G compatible dual sim card.

The principle of a Cut Dual Sim Card is based on cutting out the golden chip in the middle of 2 standard sized sim cards (Mini Sim) and then fitting the two chips into the Cut Dual Sim Adapter, which has the size of a regular sim card. So in the end you will have 2 sim cards in one dual sim card being universally compatible with phones that have a sim card slot for standard size sim cards.

The Cut Dual Sim Card comes with an onboard IC Controller (chip) which provides switching between the 2 sim cards through a menu which is displayed in the cellphone.

 

In order to communicate with this application coming from the dual sim card, the cellphone must provide an interface, the STK or Sim Toolkit. Most cellphones do come with a built-in Sim Tool Kit.

Over the years other sim card formats have been becoming more popular, which are the micro sim and the nano sim format. The iPhone 4 is an example of a cellphone requiring a micro sim card, the Samsung Galaxy S6 and iPhone 6 are exaples for cellphones requiring a nano sim card.

These cellphones can also be equipped with a dual sim card, a so-called No Cut Dual Sim Card.

No Cut Dual Sim Cards come with 2 slots for sim card, the one slot going into the cellphone’s sim slot being for Microsim such as for example the I-42 Dual Sim Adapter for iPhone 4, or Nano Sim (see NC2 S6 Dual Sim Adapter Samsung Galaxy S6) while the second sim card slot on the dual sim card hosts a standard sized sim card (Mini Sim).

Depending on the cellphone’s architecture, the second sim on the dual sim card will be placed inside the phone on top of the battery but under the cover (see NC2 S5 Dual sim Adapter Samsung Galaxy S5 as an example), or outside on the cellphone’s back and protected by a pouch (see most iPhone dual sim cards)

Just as the Cut Dual Sim card, the No Cut Dual Sim Card also comes with a chip which will use the cellphone’s Sim Tool Kit (STK) interface in order to display a menu in the phone where the user can select the sim card he wants to use.

A dual sim adapter is an intelligent device. Using it in a smart way really makes this device shine:

A smart way could be to forward calls in case a number is not reachable to the other number (the one that is active at a given moment). Configuring this kind of call forwarding on both sim cards is a very efficient way to benefit from the dual sim device and may be an alternative to purchasing a Dual Sim Smartphone and, if you are an IOS user, upgrade your device to dual sim functionality.

Smartphones running world’s most popular operating system Android can be upgraded with a dual sim card for Android and become a dual sim smartphone with 2 slots for sim cards.

This way the gap between a regular 1-sim based Android smartphone and its dual sim based dual sim smartphone counterpart can be closed.

Dual Sim Cards for Android come in 2 forms: Cut and No Cut Adapter.

Using a phone’s Sim toolkit as interface to communicate with the application coming from the dual sim card no further  software installation is required.

These days most Android smartphones mainly come with sim card slots for micro sim or Nano sim cards. As an example Samsung Galaxy S4 requires a micro sim card, whereas Samsung Galaxy S6 requires a nano sim card.

As a supplier of dual sim adapter cards for Android, 2-phones-in-1™ have filled this gap by developping the NC dual sim card series.

The NC Dual Sim card adapters are No Cut Dual sim cards meaning that sim cards do not have to be cut.

They come in various shapes: either a combination of Minism and Minism Slot such as the NC1 Android Dual Sim Card for Samsung Galaxy S2, Micro sim and Mini Sim version such as the NC2 S4 Android Dual Sim Card for Samsung Galaxy S4. The third available shape is a combination of a Nano Sim slot and a standard size slot such as the NC2 S6 Android Dual Sim Adapter card for Samsungs Galaxy S6 Smartphone.

More flexibility for the 2nd sim slot on the adapter can be achieved by adding a sim adapter kit like sim mate, available in the webshop. With this kit you can use any sim card shape for sim 2.

While the amount of Dual Sim based Android Smartphones is undoubtfully increasing, there is still a huge market for Android Dual Sim Cards. Not everybody needs to be constantly available on 2 lines and may only need a convenient way of switching inbetween 2 sim cards.

By wisely choosing a suitable provider and using the Android smartphone’s call forwarding options an Android Dual sim card can definitely compete with a  Dual Sim  Smartphone.
