Super SIM, a combination of a SIM and a Memory card!

-

SIM cards are essential for our daily to daily use. They allow a person to connect to the service provided by the network operator. Same for the memory card, whenever the storage of our smartphone runs out of space, we start deleting files or back them up to the cloud or our PC. In such situations, we use a memory card as some smartphones give you expandable storage.

But as we know, some smartphones of today’s generation comes with a Hybrid slot which restricts the use of two SIMs and one memory card. So you can either choose one SIM and a memory card or just two SIMs with no memory card.

Also, everybody knows that a smartphone requires a SIM card to work and a Memory card in terms of low storage. But what if we merge these two things and create something that does both of our work. In other words, you can use both your SIM card and your memory card in a single card if you use a Super SIM.

What is a Super SIM?

The Super SIM was first announced last year in China. It combines a SIM card and a MicroSD card into a single card or slot. These Super SIMs come into numerous capacities that start from 32GB and go up to 128GB. The read and write speeds of these Super SIM lies between 90MB/s and 60MB/s, respectively.

In comparison to a regular SIM card (128KB), a Super SIM can hold up to millions of data. The Super SIMs contain a one-click backup and restore option, which helps you to restore your old data on your new smartphone easily. As for security, the Super SIMs come with CC EAL6+ security certification, which protects your data from various issues.

Pros of Super SIMs

  • You don’t have to choose between a SIM card and a memory card if your smartphone has a hybrid tray slot.
  • For Manufacturers, you don’t have to create a triple sim slot or a dedicated MicroSD slot. You can use the space to enhance your smartphones with features like a bigger battery.

Cons of Super SIMs

  • Limited to China right now.
  • It is expensive. A 32GB Super SIM sells for ¥99 (~$14) while a 64GB card sells for ¥199 (~$28).
  • The Super SIM can only work in a hybrid slot smartphone.
  • Adoption (If more network operators don’t adopt the Super SIM, it will never be mainstream.)
  • The hassle of replacing your old SIM with a Super SIM.
