Setting Up Your New Smartphone for the First Time: A Complete Walkthrough

Day one with a new smartphone is the day most older adults form their lasting impression of whether the device will be a friend or a frustration. The good news: with about ninety minutes of patient time, a notebook, and a cup of tea nearby, almost anyone can get through the setup process with their dignity and the phone's calm both intact. This walkthrough covers iPhone and Android side by side. Wherever the two diverge meaningfully, we describe both paths.

Before you open the box

Pick a calm afternoon when you won't be interrupted. Have nearby: the Wi-Fi password (written down, not memorised), your email password for whichever email account you use most, and — if you're replacing an old phone — the old phone, fully charged. If you don't have a Wi-Fi password handy, ask the family member who set up your home internet, or look for a sticker on your internet router with the network name (often called the "SSID") and a password printed next to it.

What's inside the box

You'll find the phone, a charging cable (USB-C on most current phones), and a paper booklet with safety warnings. Modern iPhones and Pixels no longer come with a wall plug — the cable plugs into one end of the phone and the other end into a USB-C wall adapter you buy separately, or into a laptop. If you don't already have a wall adapter, any 20-watt USB-C wall charger works (around US$20). Don't worry if your old wall charger from a previous phone has a different plug shape; trying to force it in can damage the new phone.

The SIM card or eSIM

Your phone needs a SIM card to make phone calls and use cellular data (the internet connection that works outside your home). On older phones the SIM was a physical chip; you may have one already from your previous phone. On most phones sold in 2025 or later in the United States, the SIM is "eSIM" — an electronic SIM stored on the phone itself, with no physical card to install.

If you bought your phone from your carrier (Verizon, AT&T, T-Mobile, or a regional provider), the eSIM is likely already activated and ready to use. If you bought it unlocked from Apple or Google, you'll need to call your carrier and ask them to "activate eSIM" for your phone — the carrier will either text you a code or walk you through their app. This is the one step where having a family member nearby is genuinely helpful, because the carrier may need to read your driver's licence number for identity verification.

Powering on and language

Hold the side button (the long button on the right side of an iPhone, on the right side of most Androids) for three or four seconds until you feel a vibration and see the screen light up. The first screen says "Hello" in many languages. Tap once anywhere on the screen, or — on an iPhone — slide up from the bottom edge to start.

Next: language. Tap English (or your preferred language). Then country or region — pick the United States if you're in the US. The phone may ask for "quick start" if there's another iPhone nearby; if you're moving from an Android or starting fresh, tap "Set up manually." On Android, the equivalent screen is "Welcome" and "Start." Tap Start.

Connecting to Wi-Fi

You'll see a list of Wi-Fi networks. Find the name of your home network (the one on your router sticker). Tap it. Type the password exactly — capital letters matter. If the password has special characters like an exclamation mark, look on the keyboard for the "123" or "?123" button to find the numbers and symbols. The phone will confirm "Connected" with a small checkmark.

Why this matters: from here on, the setup downloads software updates and signs in to accounts using Wi-Fi. Using cellular data would work but is slower and may eat into your monthly data allowance.

Apple ID or Google Account

This is the step that confuses more new users than any other. An Apple ID (on iPhone) or Google Account (on Android) is the email-and-password combination that ties everything on the phone together — your contacts, your photos in the cloud, your purchased apps, your iMessage. It is not the same as the email address you've been using for years; it just usually uses that same address as its username.

If you've never owned a smartphone before, you'll be prompted to create one. Use your most-used email address. Pick a strong password (covered in our password guide) and — this is essential — write it down in a notebook you keep at home. Forgetting this password is the single biggest reason seniors lose access to their phones. Write it down. Twice. In two different places.

If you already have an Apple ID or Google Account from a previous phone or a computer, sign in with that existing one. The phone will remember your old apps and contacts where possible.

Transferring data from an old phone

If you have an old phone, this is the easiest moment to move everything over.

• Old iPhone → New iPhone: Bring both phones close together. The new one will show "Quick Start." Follow the on-screen instructions; you'll be asked to point your old phone's camera at a pattern on the new phone's screen, like a small fingerprint. The transfer takes 15–30 minutes.
• Old Android → New iPhone: On the old Android, download the free "Move to iOS" app from the Play Store. Open it and follow the prompts. On the new iPhone, when prompted, tap "Move data from Android."
• Old iPhone or Android → New Android: Use a USB-C-to-USB-C or USB-C-to-Lightning cable (whichever fits your old phone) and follow the on-screen prompts.

If you don't have an old phone, tap "Don't transfer apps & data" and move on. You can always add contacts manually later.

Face ID, Touch ID, or PIN

The phone wants a way to know it's you holding it. You'll be offered Face ID (on most newer iPhones), fingerprint unlock (on Android and iPhone SE), or a PIN. Always set a PIN as a backup, even if you use face or fingerprint. The PIN is your fallback for the inevitable morning when your hands are wet from doing dishes and the fingerprint scanner won't read.

Choose a six-digit PIN that isn't your birthday, your spouse's birthday, or 123456. Write it down. The PIN protects everything on your phone including your banking, your email, and your photos — treat it like the key to your front door.

The first task: a phone call to a family member

Before you set anything else up, do one thing: make a phone call to a family member to confirm the phone works for the basic purpose. Open the green phone icon, type the family member's number on the keypad, tap the green call button. When they pick up, tell them you're calling from your new phone. Hang up. That's it.

The reason for this is simple: setup screens can give you the false impression that the phone is working when in fact the carrier didn't finish activating your line. A two-minute call confirms everything is genuinely connected before you spend the next hour installing apps.

Next steps

From here, your day-one work is to adjust the dozen settings that make a new phone calmer and easier to read. See our 12 day-one settings guide. After that, the most useful next step is making the text bigger, followed by setting up video calling with the family member you just rang.
