If you’ve just unboxed your device, learning how to set up cellular on new iPhone is one of the first things you’ll need to do. Whether you’re inserting a SIM card or activating an eSIM, the process is simple once you know the steps.
This guide covers everything you need, from preparing your carrier plan to completing activation. We’ll also show you how to transfer your number from an old iPhone and troubleshoot common issues so you can get connected quickly.
1. Things You Need Before Setting Up Cellular
Before you begin the process of activating your new device, it’s important to make sure you have everything ready. Preparing these essentials will make the setup much faster and smoother.
Active Carrier Plan
First, you need an active mobile plan from a supported carrier such as Verizon. If you’re transferring service from an old phone, ensure your account is active and eligible for transfer. New users may need to sign up for a plan before starting. Without an active plan, your iPhone won’t be able to connect to a cellular network.
Wi-Fi Connection Requirement
A stable Wi-Fi connection is highly recommended during setup, especially for eSIM activation. Your iPhone needs internet access to communicate with your carrier and download the necessary configuration. While some physical SIM setups may work without Wi-Fi, most modern activation methods rely on it.
QR Code or SIM Card Ready
Depending on your setup method, you’ll need either a physical SIM card or an eSIM QR code provided by your carrier.
For eSIM users, keep the QR code accessible (printed or on another device) for scanning. If you’re using a physical SIM, make sure it’s properly sized (Nano-SIM) and ready to insert into your iPhone.

While setting up your device is usually smooth, you may run into a few issues along the way. Understanding these common problems can help you quickly fix them.
- No service or “SOS Only”: Restart your iPhone, check if your SIM is inserted correctly, or ensure your eSIM is activated. You may also need to reset network settings.
- eSIM not activating: Make sure you’re connected to Wi-Fi and scan the correct QR code. If it still fails, contact your carrier for reactivation.
