Are Sim Cards Universal for Android and iPhone?

By John Adebimitan

If you’ve recently switched phones, you might be worried about the compatibility of your SIM card on both devices. First, let’s dive into an overview of SIM cards, the types, and if we can find SIM cards universal for Android and iPhones.

SIM cards safely store the service key of the subscriber used to identify themselves to the phone operators. There are mainly three types of SIM cards in use. They are the Standard SIM, the smaller Micro SIM, and the smallest of them, the Nano SIM.

  • Standard SIM Card: The Standard SIM card remains the largest of the three types of SIM cards and is the oldest. It was generally used in phones before 2010, with some exceptions. The Standard SIM measures 25x15mm and is also known as 2FF. It is very hard to find a phone using Standard SIM, but it may sometimes be found on basic feature phones.
  • Micro SIM Card: The Micro SIM card is similar to a Standard SIM card, except that extra plastic around the circuit board has been removed. The only real difference between a Standard SIM and a Micro SIM is the size of the plastic around the microchip.

The Micro SIM card was developed to make smartphones slimmer and lighter. High-end brands like Apple and Samsung were the first to introduce the Micro SIM chip on their devices.

  • Nano SIM Card: This new kid on the block is used on most of the latest devices. The Nano SIM card is almost 50 % smaller than a Micro SIM, measuring 12.3×8.8mm. It first made its appearance in the Apple iPhone 5.

Are sim cards universal for Android and iPhones?

No, SIM cards are not universal. In general, you can only use SIM cards from GSM carriers on compatible phones. So, you must check your SIM card to see what size it is, the carrier, the country where the carrier is operating, and confirm that your Android or iPhone isn’t locked to a specific carrier.

On the other hand, almost all phones from the same brand and model tend to have the same SIM card sizes irrespective of the country where said device is being sold.

What happens if you take out your SIM card and put it in another phone?

Some people often switch their SIM cards from one device to another. But what happens when one does this switching? Well, if the phone you are switching to is compatible with your SIM card, calls and text messages will be received on the phone. However, old text messages and calls won’t show up on the phone. This is because data such as calls and text messages are stored on the device and not the SIM card.

If you save your contacts on your SIM card, they will be displayed when you put the SIM card in the other phone. However, if you do not copy the contacts to your phone, they will disappear once you remove the SIM card.

There are some other things to know. For example, if your device is locked to a specific carrier, inserting another carrier’s sim card may not work. So, if you’d like your device to work universally irrespective of the sim card you insert, you’d either want to unlock or ensure that it’s not locked to any carrier.

Are SIM cards made for specific phones?

Since SIM cards come in three different sizes, the size that your phone accepts will depend on the phone’s brand, size, and date of manufacture. As such, when you want a new SIM card, you need to know which size your phone is compatible with and order one of the correct sizes.

Fortunately, most cellular carriers have handled this issue very well. When you order a SIM card from a popular provider, they’ll give you a Standard-sized one. However, the SIM card will have perforations that allow you to transform it into its Micro or Nano forms by tearing parts off it.

If you use an iPhone or an Android device and you are wondering if there are SIM cards universal for Android and iPhone, then you may have most likely gotten your answer from this article. Standard SIMs are fast becoming obsolete, and it is now the age of micro, nano, and eSIMs.

For more information on the type of SIM card your device is compatible with, check out the specifications on the box. The SIM card may be universal for Android and iPhone, but the device will also determine if it is or not.
