Are you looking to transfer service from an Android phone to an iPhone, and are wondering if you can use the same SIM card?

This is a common question, especially from people who are transferring their service for the first time.

So, do Android SIM cards work in iPhones and if so, how can you ensure it transfers safely?

In this article, I’ll be covering everything that you need to know!

Can You Put An Android SIM Card In An iPhone?

SIM Card

Yes! It is completely possible to put an Android SIM card into an iPhone, as long as the SIM card is the same size, and will fit in the iPhone’s SIM card tray.

This is because SIM cards are not tied to specific phone models, and can be freely be moved around phones of any type – again, as long as they fit.

Thankfully, SIM cards come in just three sizes – standard, mini, and micro. So, manufacturers have created SIM card adapter kits that will help out, even if the SIM sizes don’t match. More on that later!

For now, just understand that the answer is yes – as long as it will fit, Android SIM cards can be used in iPhones, and vice-versa.

Exception: Newer eSIM iPhone Models

There is one exception to this rule however, and that is in regards to Apple’s most recent iPhone models.

Starting with the iPhone 14 and the iPhone 14 Pro, Apple no longer offers a physical SIM card slot with their newest iPhone models – at least those sold within the United States.

Therefore, since there is no longer a SIM card tray to actually put a SIM card in, you won’t be able to transfer your Android SIM card into it. Instead, you will need to use the phone’s built-in eSIM functionality in order to get service on the iPhone.

If you are permanently switching service over to your new iPhone, this generally isn’t a big deal, and setting up eSIM only needs to be done once.

Apple has faced criticism however by people who switch SIM cards frequently (such as those who use separate phones for traveling), as eSIM is actually more of an inconvenience for little practical benefit.

If you need help activating service on your phone, contact your carrier for assistance. For reference, here are the customer support numbers for four of the largest cellular providers within the United States:

AT&T: 1-800-331-0500

Verizon: 1-800-837-4966

T-Mobile: 1-800-937-8997

Sprint: 1-888-211-4727

How SIM Card Adapters Work

As mentioned earlier, it may be possible to fit your Android SIM card into an iPhone, even if the sizes aren’t exactly the same!

This is made possible by using something called a SIM card adapter.

As you can see in the picture above, this particular SIM card adapter comes with three different SIM card sizes, to match the three available sizes that different SIM cards may come in.

So, you just place your SIM card inside the appropriate adapter, and then put it into the iPhone with ease.

For reference, iPhones use nano-sized SIM cards, so that will be the one you’ll want to use. Although this particular SIM card adapter advertises iPhones 4, 4S and 5 on the package, it actually works for all iPhones that have a SIM card tray (so, iPhone 13 and earlier.)

Remember What SIMS Actually Are!

So, we now know that Android SIM cards can be used in iPhones, as long as they are the same size SIM that iPhones use, which is nano.

We also now know that adapters are available to convert your SIM card to a different size.

So, why does this work so smoothly? In order to answer that question, it’s important to understand how SIM cards actually work!

Contrary to popular belief, SIM cards aren’t actually tied your specific phone, or even your specific phone model.

Instead, SIM cards are simply a device issued by your cellular provider that communicates with their network, and identifies you as one of their customers. Then, their systems can look up your phone number and cellular plan, enable your services, and route calls to your assigned number.

In fact, SIM itself stands for subscriber identity module – it is literally just used to identify you, and provide you service!

This means it can be freely swapped out to any other phone as you wish, as long as it will fit. As long as the phone isn’t locked to a different carrier, it will work!


Thankfully, you can put an Android SIM card into an iPhone without any issues, as long as it is the appropriate size.

Additionally, you can always use an adapter if your current SIM card is incompatible.

Because SIM cards are tied to your cellular plan and not the specific model of your phone, you are welcome to move them between phones as you wish, without experiencing any issues or loss of service.

I hope that this article has answered all of your questions. If you have any other questions about SIM cards, please ask them using the comment form below and I’ll be happy to help out.

Wishing you the best,
