Types of SIM card

Nano SIMs are the most used SIM in newer (2014 and onwards) smartphones. Micro SIMs were most used before that.
 

The main difference between a Nano and a Micro SIM is the size of the plastic around the microchip. Most mobile networks now provide a single adjustable card that you can snap out of the plastic to the correct size.

Types of memory card

An SD or memory card is a digital storage card you can use to expand storage space on your device. SD is short for Secure Digital.

SD cards come in different sizes. The most common are standard SD cards and micro SD cards.

Most smartphones and tablets with expanded storage capability take micro SD cards.

Memory cards are available to purchase from most digital retailers, online, or in supermarkets. Be aware that while cheaper memory cards can save you money in the short term, they are more likely to become corrupted and lose your data and images.

What is the difference between SDHC and SDXC?

SD cards come in a range of storage capacities including SDHC (Secure Digital High Capacity) and SDXC (Secure Digital Extended Capacity).

Class transfer speed refers to the speed of reading and writing images. The transfer speed will be designated by a class and not whether it is SD, SDHC or SDXC.
