What the heck is a sim card?

SIM stands for Subscriber Identity Module, and it’s a removable card inside your cell phone that stores data unique to its user. Basically, it tells your wireless provider who you are, and it’s the thing that allows you to connect to their network. Without it, you can’t access your data or make phone calls, you’d just be rolling with WiFi.

Since the SIM card holds your identifying info, you can easily move it from phone to phone to access the same network and the same phone number. But we won’t tell if you still hit people with a, “new phone who dis?”

Sim Card sizes

SIM cards come in three different sizes: Standard (Mini), Micro, Nano. To make life easy, some awesome carriers (ahem, like us) provide a 3-in-1 SIM card, which means we give you a triple cut SIM and you pop out the size that fits your device.

A few notes on sizes:

  • Standard (Mini) SIMs fit older devices like iPhones up to the 3GS model or Samsung Galaxy S
  • Micro SIMs fit devices circa 2012-2013 like the iPhone 4s or Samsung Galaxy S5
  • Nano SIMs fit the new guys like iPhone 5 and above or Samsung Galaxy S6 and above


GSM and CDMA are the two ways that phones connect to a wireless network. Mint Mobile runs on GSM, which stands for Global System for Mobile communications and requires a SIM card to work. It’s now considered the standard and the one most widely used around the globe.
Keep your number

Transferring your phone number to Mint is easy. You’ll just need a few details from your current (overpriced) carrier—your account number, pass/pin code, and billing zip code—that you’ll enter during activation to complete the port/transfer.

Get a new number

Or, if you want to start Mint-y fresh, we can assign you a new phone number. The choice is yours!

FAQS - Sims

Depends on your device’s make and model. All plans come with a 3-in-1 SIM card that includes mini, micro and nano sizes to fit your phone. Just punch the size that will fit your phone and use the handy sim ejector tool that we gave you to pop out the sim tray.

Not sure where your SIM card is located? Check your phone manual or just ask Google for the location of the SIM card in your phone and which size you’ll need.

If you need help inserting the SIM, the Mint Fox will talk you through it step-by-step in this instructional video.
