The classical SIM Card of the early 2000 is likely to get replaced by a series of smaller more efficient micro and nano SIM card models. When the first GSM mobile phones were launched in the 90s, SIM cards were still the size of a credit card. Although the actual chip was only slightly larger than today’s, the user had slide a big card onto the device.

Soon it was clear that the plastic around the chip is actually superfluous – the first SIM card with the chip came to breaking out into the market and remained – until Apple in the iPhone 4 Micro SIM was introduced – with much less plastic. Nevertheless, the Micro SIM measuring few millimeters superfluous border around the chip, this has been recently followed by the iPhone 5 and Nano SIM card that only consists of the chip and no plastic edges.

This is great for mobile phone designers who have a little more room for another element in their devices but on the other had, it’s a bit tedious for the customers who need to get another new SIM card. For most, however, is currently the switch to the Micro SIM in the foreground. Besides the iPhone 4 also uses the Samsung Galaxy S3 on the smaller card. The network operators deliver new SIM cards, the user can use them either as a large version or the Micro SIM – once again breaking out the principle. So next time that you are interested in upgrading your mobile phone please consider the size of the appropriate SIM card because this is no longer a straightforward task.
