Activate eSIM Carrier Plan Ready to Be Installed on iPhone

If your iPhone shows “Carrier Cellular Plan Ready to Be Installed,” it means your carrier has sent a new eSIM profile to your device and you need to complete the activation by tapping the notification and following the on-screen steps. This usually happens when you buy a new iPhone, switch carriers, or add a second line. The fix is straightforward: tap the notification, confirm the plan, and restart if prompted.

What This Notification Means

An eSIM is a digital SIM built into your iPhone that stores your carrier profile just like a physical SIM card. When your carrier provisions a new eSIM, they send a QR code or a push notification to your device. The “Carrier Cellular Plan Ready to Be Installed” alert appears when the carrier has already pushed the profile to your iPhone and it is waiting for your confirmation.

This notification is not an error. It simply means the activation process is paused until you approve it. On iPhones with iOS 16 or later, you may also see this message when you transfer a plan from an old iPhone using Quick Start, or when you add a new line to an existing eSIM.

How to Install the eSIM Plan

Tap the notification “Carrier Cellular Plan Ready to Be Installed.” If it disappears, go to Settings > Cellular > Add Cellular Plan.
When the plan appears, tap Continue at the bottom of the screen.
Choose a label for the line (e.g., Personal, Business, Travel) or create a custom label.
If you have multiple lines, select which one will be your default voice and data line.
Tap Done. Your iPhone will activate the eSIM, which may take a few minutes.
If asked to restart, press and hold the side button with either volume button to power off, then turn it back on.

After installation, go to Settings > Cellular and confirm the new plan shows “On.” You can also check that your phone number appears correctly under About in Settings.

What to Do if the Notification Won’t Go Away

Sometimes the alert stays on the lock screen even after you install the plan. If that happens, force restart your iPhone (press and release volume up, then volume down, then hold the side button until the Apple logo appears). If the notification still persists, go to Settings > Cellular > tap the plan and toggle Turn On This Line off and on again.

If the plan never appears in Settings, contact your carrier. They may need to resend the eSIM profile. Do not delete the plan unless you are sure you want to remove it, because you may need a new QR code from your carrier to re-add it.

Common Problems and Fixes

No notification after purchasing a new iPhone: Go to Settings > Cellular > Add Cellular Plan and scan the QR code your carrier provided.
“Unable to Add Cellular Plan” error: Make sure your iPhone is updated to the latest iOS, then restart and try again. If it still fails, ask your carrier to issue a new QR code.
eSIM installed but no service: Check that the plan is turned on, then toggle Airplane Mode on and off. If that doesn’t work, reset network settings (Settings > General > Transfer or Reset > Reset > Reset Network Settings). This will not erase your data, but it will forget Wi-Fi passwords.
Two eSIMs on one iPhone: Only iPhone XS and later support dual eSIM (or one physical SIM plus one eSIM). You can have multiple eSIM profiles stored, but only two active lines at a time.

How to Transfer an eSIM from an Old iPhone

If you’re moving from an older iPhone, you can transfer the eSIM without contacting your carrier. Place both phones near each other, then on the new iPhone go to Settings > Cellular > Add Cellular Plan. The new iPhone will detect the old one and offer to transfer the plan. On the old iPhone, tap Transfer and confirm. The carrier must support eSIM Quick Transfer; most major carriers do.

If you already erased your old iPhone before transferring, you’ll need to contact your carrier to reissue the eSIM. That’s why it’s best to transfer before wiping the old device.

eSIM vs. Physical SIM

eSIMs have several advantages: you can switch carriers without waiting for a physical SIM to arrive, you can have two lines on one phone (e.g., work and personal), and it’s easier to activate a plan while traveling. The main downside is that if your iPhone is lost or stolen, you cannot simply remove the SIM to prevent misuse; you must contact your carrier to suspend the line.

Physical SIMs are still useful if you frequently swap phones or travel to countries where eSIM support is limited. Most iPhones sold today support both, so you can choose whichever is more convenient for each line.

Frequently Asked Questions

Will installing an eSIM erase my data?

No. Installing an eSIM does not affect your photos, apps, or settings. It only adds a cellular plan to your device. Your data remains untouched.

Can I have two eSIMs active at the same time?

Yes, on iPhone XS and later you can have two active eSIM lines simultaneously. You can also have one physical SIM and one eSIM. However, you can store more than two eSIM profiles, but only two can be active at once.

What if I delete the eSIM by mistake?

If you delete a plan in Settings > Cellular, you can usually re-add it by scanning the QR code your carrier provided or by contacting them to send a new one. Deleting the plan does not cancel your service; it just removes it from your iPhone.

Why does the notification keep appearing after I installed the plan?

This can happen if the carrier’s profile was not fully downloaded. Try restarting your iPhone, then go to Settings > Cellular and confirm the plan is on. If it still appears, contact your carrier to resend the eSIM profile.

Can I install an eSIM on an iPhone that is locked to a carrier?

Yes, but only if the eSIM is from the same carrier that locked the phone. A carrier-locked iPhone will not accept an eSIM from a different carrier until it is unlocked. Check with your carrier about unlocking eligibility.

Does eSIM use more battery or data?

No. eSIM uses the same cellular radio as a physical SIM and has no measurable effect on battery life or data usage. The only difference is how the SIM information is stored.
