What does SIM-free mean on iPhone 15?
A SIM-free iPhone 15 is a device not tied to any carrier, offering the flexibility to choose or switch carriers and use local SIM cards when travelling.
Unlike carrier-locked phones, SIM-free models come 'unlocked', allowing their use with any compatible carrier worldwide. A SIM-free iPhone deal gives you greater freedom and convenience, especially if you are a frequent traveller or prefer not to be bound to a specific carrier or contract.
You can purchase a SIM-free iPhone and enter into a separate SIM-only contract with a network carrier for mobile service. This combination allows you to own the phone outright while having the flexibility of choosing your preferred service plan.

Why does iPhone 15 have no physical SIM?
The US models of the iPhone 15 switched to eSIMs to streamline activation and improve security. An eSIM (embedded Subscriber Identity Module) is a rewritable chip inside your mobile device. It lets you activate a new mobile plan electronically without inserting a physical SIM card.
This allows you to use multiple eSIMs and phone numbers on one device, making switching carriers and managing plans easier. Additionally, it enhances security by making it harder to steal and misuse the phone.
How to add eSIM to iPhone 15 without a SIM Card?
To add an eSIM to your non-US iPhone 15 without a physical SIM card, begin by turning on your new iPhone and following the onscreen instructions.
If your network provider supports eSIM Carrier Activation, the eSIM will be assigned to your iPhone when you purchase it. Simply follow the activation steps.
With eSIM Quick Transfer, you can transfer the eSIM from your old iPhone to your new one without contacting your provider. Ensure you sign in on both iPhones with the same Apple ID, that the old iPhone is nearby, unlocked, has Bluetooth on, and is running iOS 16 or later.
If you can’t find these options, contact your network provider to activate your eSIM using a QR code or the provider's iPhone app.
To do this, open the Camera app on your iPhone, scan the QR code provided by your carrier, and follow the prompts.
You can also manually enter new eSIM information by going to Settings > Cellular > Add Cellular Plan > Enter Details Manually. This process allows for easy setup and activation of your eSIM without needing a physical SIM card, providing flexibility and convenience to shift between multiple phone numbers and plans on a single device.
