Switching to a local physical SIM card is a popular method for avoiding costly roaming fees or international charges. In most cases, you can pick one up at the airport or search for one around town.

Before you do that, however, take a moment to refresh yourself on the finer points of iPhone SIM cards. Here’s the scoop on them, plus everything you need to know about switching between SIM cards while you travel.

What to Know Before You Switch SIM Cards on an iPhone

Many people wonder if you can really just switch SIM cards on an iPhone. Yes, you absolutely can. However, there are a few things to know before you do it:

• If you intend to use a third-party SIM card, your phone must be unlocked: This won’t be a problem if you purchased your phone directly from Apple as they generally sell them unlocked. However, if you purchased it from a carrier – especially in the U.S. – it’s likely locked.

Usually, just calling your carrier and explaining that you’ll be traveling abroad is enough to get them to unlock it. However, that doesn’t always work, because carriers prefer that you use their international data plans. In that case, use a third-party alternative to unlock your phone.

• Your contacts, apps, and data aren’t stored on your SIM card: Unlike other smartphones, iPhones don’t store details like contacts on the SIM card. Instead, all your information is backed up to cloud storage. That means removing your SIM card while you travel won’t affect your ability to access your information. The only data that’s actually on your iPhone SIM card is your customer data. Apple uses that to help track your phone.
• All current iPhones use a nano-SIM card: It’s worth noting that all iPhones manufactured since 2012 use a nano-SIM card. These are the smallest SIM cards currently available on the market. Keep this in mind, because smartphones using micro-SIM cards still exist and you may buy the wrong one abroad if you’re not careful.

Removing SIM cards from your iPhone

How to Remove a SIM Card from an iPhone

All iPhones come with SIM card slots located on their sides. For iPhones, the SIM tray is located on the left or right side. If you’re looking along the edge, you should see a small oblong shape with a pinhole next to it. That’s your SIM card slot. With your phone turned off, follow these steps to remove your SIM card:

Insert the SIM-Eject Tool

Insert the SIM-eject tool straight into the pinhole. If you don’t have one, a paperclip will work in a pinch. If you’re having trouble finding a paperclip that’s narrow enough, a straight back earring will also work. Press it in firmly, you should feel a click. Remember that you shouldn’t have to force it.

After the click, the tray pops out.

Remove the SIM Card

The SIM card should come loose from the tray easily. Don’t try to force it if it’s stuck, as that may mean your tray is bent. Likewise, don’t use tweezers or anything hard to knock out as that may scratch the card. Store your card someplace safe (or put another SIM card into your phone) and you’re set.

How to Add a SIM Card to an iPhone

Adding a SIM card to an iPhone is just as easy as removing one. Just follow these steps:

• Open the tray: Turn off your phone, then follow the steps above to open the tray again. Pull it all the way out before trying to seat your SIM card.
• Locate the clipped corner: To help you tell which way the SIM card should go into the phone, you’ll notice that one of the edges looks “clipped.” Match the edge on your SIM card with the slot on the tray.
• Insert the SIM card: Set the SIM card into the tray as straight as possible. Don’t try to insert it at an angle or it may not seat properly. Likewise, avoid touching the gold part of the SIM card while doing this to prevent oils or dirt from your fingers from smudging it. Slide the tray back into the phone. It should close with a click.
