![]() Samsung, Nokia, and HTC are just a few of the manufacturers that adopted the new Micro-SIM. When Apple released the iPhone 4 with the micro-SIM, it became the standard for most smartphones. It turned out to be scaled down – the card only needed its excess plastic to be cut from it. In addition, despite its smaller size, the micro’s performance wasn’t impacted at all, as chip’s contact area remained the same. In addition, the micro-SIM was designed for backward compatibility, meaning it can work with input generated by an older version of the SIM (such as the Mini-SIM). Back then, its purpose was clear: if a device was too small to fit a mini-SIM, you’d have to use the micro-SIM. Believe it or not, it was first introduced in 2003. Surprisingly, the Micro-SIM wasn’t some new flashy SIM developed for the latest iPhone. Wanting to save precious room for its newest generation of smartphones, Apple switched from using the standard Mini-SIM to the Micro-SIM once the iPhone 4 hit shelves. For over a decade, this was the standard, which made switching phones a breeze. If you wanted a new phone, all you’d need to do was take that SIM out, pop it into any phone and suddenly your phone number would be transferred to the new device. Essentially, it was your entire phone on a card. Introduced in ‘96, it was the standard used in every phone and it made the GSM folks happy. But prior to the launch of the iPhone 4 in 2010, we really only had one SIM card size. When skimming the evolution of the SIM card, you likely noticed that they’ve become much smaller. Although minuscule compared to prior versions, the Nano still holds the same amount of data as earlier SIM cards. A trimmed version of the Micro, the Nano is the smallest and used on today’s iPhones. The Micro SIM card is essentially a standard SIM card with the extra plastic around the circuit board trimmed off. Today, these are mainly used on older phones. Of the four, the Standard is the original SIM and the largest. There are four basic sizes of SIM card: the standard, the micro, nano, and esims. Maybe they just wanted to stay ahead of the curve and throw competitors off their trail.Ī SIM Card is a chip that all devices carry. Perhaps Apple was peeved they had to use a SIM card from 2003 on the shiny new iPhone 4. If you thought Apple was done using smaller SIM cards, think again. If you absolutely need antivirus for whatever reason, then Malwarebytes is one of the better trusted ones.When skimming the evolution of the SIM card, you likely noticed that they’ve become much smaller. ![]() This prevents any app that wasn't obtained from Google Play Store from being installed (which could include malicious apps that are inadvertently downloaded). Turn off "Unknown Sources" in Settings>Security (or in Special App Access on newer phones). This allows Google to periodically scan your phone's apps to look for malware.ĥ. Turn on Google Play Protect features in Settings>Google>Security (or in the Play Store settings). Read a bunch of app reviews before installing an app to look for any complaints about adware or suspected malware.Ĥ. Only install apps from well-established app sources like Google Play Store or Amazon Appstore. Never ever tap on a link that appears in a popup while browsing, especially if they're warning you that your phone is infected - they're just trying to scare you into installing some bogus "antivirus" app that is probably malicious itself.ģ. Avoid shady websites that deal with things like porn, gambling, and "free" (aka pirated) apps/music/movies.Ģ. For the most part, it's still quite difficult to get an actual virus on your phone, because malware requires you to manually accept the installation (which is why they try to fool you into thinking you're installing something legitimate).
