You may have noticed over the last couple of years mobile phone manufacturers are starting to introduce dual SIM card functionality into all their phones. This is true of both the iPhone XS range and the Samsung S10 range. However, not many people realise that you can also use two SIM cards in older handset models. With that let us introduce to you the KOOSIM DS-2 iPhone dual SIM card adapter.

Suitable for almost all models including the iPhone 5, 5C, 5S, 6, 6P, 6S, 6SP, SE, 7, 7P, 8 Plus, this handy little piece of technology dramatically expands the capability of your handset. The KOOSIM DS-2 is part of a range of iPhone SIM card adapters manufactured by Chinese company Hong Kong BEIDD.

Additional products sold include a triple SIM card adapter (DS-3) and another version of the dual SIM card adapter called the DS-1. Whilst having a dual-sim function won’t replace unlocking your iPhone, it will allow you to switch between contracts.

What are the advantages of an iPhone dual SIM card adapter?

Whilst for many people the advantages are not immediately clear, having dual-sim functionality on your iPhone does have some benefits. For example, you can have one SIM card for making calls and another for data transfer or connecting to the internet.

Another advantage would be for separating work and home life. You can carry the same handset but and be available to work colleagues and family and friends at the same time. For most users though, it is more beneficial if you get your iPhone unlocked first.

Doing this means you will be able to use 2 SIM cards from different networks. As a result you can get increased coverage plus a cheaper monthly bill if you use the SIM cards correctly. Dual Citizen have some more interesting points here.

Compatible with the iPhone 5, 5C, 5S, 6, 6P, 6S, 6SP, SE, 7, 7P, 8, 8 Plus, the KOOSIM DS1 and DS-2 dual SIM card adapters are incredibly cheap, costing only a few pounds. What we did notice though was that they require you to cut your SIM cards down. For many people this would be wholly unacceptable. Just a single mistake and your SIM card is rendered completely useless.

As a result, although these devices do work, the uptake on them has been fairly low. Cutting your SIM card can be a frightening process for even the most technically savvy individual.
