How to Transfer an eSIM from Old iPhone to New iPhone in 2026
You can transfer an eSIM from your old iPhone to a new one by removing the old eSIM profile and downloading a fresh profile on your new device—no physical SIM card needed. The process takes under 10 minutes and requires only your phone number, QR code, or activation code from your eSIM provider.
Quick Summary: eSIM Transfer Essentials
- eSIM transfers are permanent—removing it from your old iPhone deletes that profile forever
- You'll need the original activation code, QR code, or refundable download from your provider
- New iPhones (XS and newer) all support eSIM; make sure your old phone is unlocked
- WiFi is essential for downloading the eSIM profile on your new device
- The transfer process is identical whether you're switching between iPhone models or upgrading iOS versions
Why eSIM Transfer Matters for Traveling
If you're mid-trip when your new iPhone arrives, a botched eSIM transfer means no maps, no WhatsApp, no ride-hailing app, and no way to contact your hotel. Getting this right the first time prevents panic at the airport or a café in Bangkok. Unlike physical SIM cards, eSIM profiles live in your phone's hardware—they can't be swapped between devices. Understanding the transfer mechanics keeps you connected during one of the most chaotic moments of travel: replacing your phone.
Is Transferring an eSIM Actually Necessary?
Not always. Many eSIM providers let you deactivate a plan and request a new download link for a different device without losing your balance or plan duration. esimiphone.com, Airalo, and Holafly all offer this flexibility. The true transfer—removing the eSIM from your old phone and reinstalling it on your new one—only makes sense if you want to keep the exact same plan active on a single new device immediately.
In practice, most travelers take a simpler route: they order a fresh eSIM plan on their new iPhone as soon as it arrives, then cancel or let the old plan expire. This works because most eSIM plans are affordable (often $5–$15 for regional bundles) and travelers rarely regret the cost of an extra few days of continuous coverage during the upgrade window.
Real Traveler Scenarios Where eSIM Transfer Helps
You're upgrading mid-trip and want zero downtime
You're in Vietnam, your iPhone 14 screen shatters, and you've got a replacement arriving tomorrow. Your active esimiphone.com plan has 5 days and $12 remaining. Rather than waste that balance, you transfer the eSIM to your new phone as soon as it's unboxed. You're online again in under 5 minutes, and your data keeps flowing without interruption.
You're testing a backup device before a long-haul trip
You own an iPhone 15 Pro and a refurbished iPhone SE for backup. Before heading to Southeast Asia for three weeks, you transfer your Airalo plan to the SE to make sure the backup phone works on the network. If something goes wrong with your primary device mid-trip, you can immediately activate the SE and restore the same connectivity.
Your old phone is being sold or gifted and you need to reset it
You're selling your iPhone 13 and keeping your active eSIM plan for your new iPhone 16. Before wiping the old phone for resale, you must remove the eSIM profile—otherwise the new owner could potentially access carrier settings (though they can't use your plan). Transferring the profile to your new phone is the secure way to handle this.

What to Compare Before Transferring an eSIM
- Remaining balance or data: Check how much of your plan you're actually using before transfer
- Plan expiration date: Transferring won't extend validity, so confirm it covers your travel dates
- Network compatibility: Ensure both your old and new iPhone models work on the same carrier networks in your destination
- Provider's transfer policy: Some (like esimiphone.com) offer free re-downloads; others charge or limit attempts
- WiFi availability during transfer: You'll need a strong connection to download the profile on your new iPhone

| Testing a backup device | Transfer—confirm compatibility | — |
| Selling old iPhone | Must transfer for security | Must transfer for security |
| Plan expires in 2 days | Buy new—not worth transfer hassle | Buy new—not worth transfer hassle |
| Backup device for emergency use | Transfer—ensures same coverage | — |
Step-by-Step: How to Transfer an eSIM Between iPhones
Step 1: Save Your Activation Code or QR Code
Before you do anything, log into your eSIM provider's app (esimiphone.com, Airalo, Holafly, etc.) and find your plan details. Take a screenshot of the QR code or write down the activation code—you'll need this on your new iPhone. Some providers email this automatically; others require you to navigate to 'Plan Details' or 'Download eSIM' to retrieve it.
Step 2: Remove the eSIM from Your Old iPhone
- On your old iPhone, open Settings > Cellular (or Mobile Data)
- Tap the plan you want to remove (you'll see your eSIM provider's name)
- Tap 'Remove eSIM' or 'Delete Plan' and confirm
- Wait for the confirmation message—this usually appears instantly
- Your old phone now has zero active eSIM profiles
Step 3: Connect Your New iPhone to WiFi
On your new iPhone, go to Settings > WiFi and connect to a stable network. Downloading an eSIM profile requires a consistent connection—don't rely on a café WiFi that drops every few minutes. If you don't have WiFi available, wait until you reach a more stable location (airport lounge, hotel, office).
Step 4: Download the eSIM on Your New iPhone
- Open Settings > Cellular > Add Cellular Plan (or 'Add eSIM')
- If you have a QR code: point your camera at it and tap 'Continue' when prompted
- If you have an activation code: select 'Enter Details Manually' and paste the code
- iOS will validate the code and download the profile—this takes 30–60 seconds
- You'll see a confirmation: 'Cellular Plan Added'
- Choose which phone number is your 'Default' for calls and SMS (you can have two if your old iPhone still has a carrier SIM)
Step 5: Verify Connectivity
Once the profile installs, turn on Cellular Data and wait 30 seconds. Your phone should connect to the local network automatically. Open a website or send a WhatsApp message to confirm you're online. If you see 'No Service,' toggle Airplane Mode off and on, then wait another 30 seconds.
Common Mistakes to Avoid During eSIM Transfer
Removing the eSIM before you have the activation code saved
This is the most expensive mistake. If you delete the eSIM before backing up the code, most providers will issue a replacement download link for free, but some charge $2–$5. Always screenshot or write down the code first.
Attempting to activate eSIM on your old phone while also installing it on your new phone
eSIM profiles can only be active on one device at a time. If you try to download the same profile on two phones simultaneously, the second activation will fail. Always remove it from the old phone first.
Transferring without checking network compatibility
If your old iPhone 11 works fine on a carrier's 4G network, your new iPhone 15 might not—newer models sometimes drop support for older bands. Check your eSIM provider's network compatibility chart before transferring. esimiphone.com and Airalo list supported networks by country on their websites.
Forgetting to change the 'Default' line for calls and SMS
If you kept your old carrier SIM in your new iPhone (for backup), iOS defaults to the physical SIM for calls and SMS. Change this in Settings > Cellular > Cellular Plans > 'Default Voice Line' and 'Default SMS Line.' Otherwise, WhatsApp and two-factor authentication codes might go to the wrong number.
Not disabling the old plan in the provider's app
Some eSIM apps (especially Holafly) let you mark a plan as 'inactive' in-app even after it's removed from your phone. If you don't do this, the app might show duplicate plans or confuse your subscription history. Always log into the provider's app after transfer and confirm the old plan shows as 'Inactive' or 'Removed.'
Best Choice by Traveler Type
Casual Tourist
You probably don't need to transfer. Buy a fresh eSIM plan on your new iPhone when you land. It's $5–$10, takes 3 minutes, and eliminates transfer risk. Only transfer if you have more than 5 days of active plan remaining and you're already stressed about upgrading.
Business Traveler
Transfer is worth it. You need continuous connectivity for email, calendar, and client calls. Transferring ensures zero downtime. Use esimiphone.com or Airalo—both support dual eSIM (one for work, one for backup) and offer fast customer support if something goes wrong.
Digital Nomad
Transfer strategically. If you're jumping between countries weekly, transferring an eSIM makes sense only if you're staying in the same region for 2+ weeks. Otherwise, buy fresh plans as you move. Keep backups of activation codes for all your active plans in a password manager (Bitwarden, 1Password, etc.).
Family Group
Don't transfer. Buy individual fresh plans for each family member on their new iPhones. It's cleaner, eliminates shared profile issues, and ensures each person can troubleshoot independently. Family plans aren't common in eSIM, so this is your most reliable option.
eSIM Transfer vs. Other Connectivity Options
| Method | Cost | Setup Time | Flexibility | Best For |
|---|---|---|---|---|
| eSIM Transfer (existing) | $0 (if provider allows) | 5 min | High—switch providers anytime | Mid-trip upgrade, short notice |
| Buy New eSIM Plan | $5–$20 | 3 min | High—multiple providers available | Most travelers, safety-first approach |
| Local SIM Card | $3–$10 | 20 min | Medium—tied to one carrier | Budget travelers, long stays |
| Hotel WiFi + VoIP | $0 | 1 min | Low—dependent on network quality | Short trips, light data use |
| Roaming (carrier plan) | $10–$100+ | 0 min | Low—high costs, slow speeds | Emergency backup only |

Can I transfer an eSIM from an iPhone to an Android phone?
No. eSIM profiles are tied to the specific device's hardware. You'll need to purchase a new plan on Android, or request a physical SIM card from your provider if they offer one.
What if my new iPhone doesn't support eSIM?
iPhones XS and newer all support eSIM. If you're upgrading from iPhone 8 or earlier, your new phone will definitely have eSIM capability. Check Apple's official specs if you're unsure about a specific model.
Can I use two eSIM plans on the same iPhone?
Yes. iPhones XS through 14 support dual eSIM (two separate profiles). iPhone 15 and newer support dual eSIM plus a physical SIM card. This is useful for business travelers who want a local plan plus an international backup.
What happens if the transfer fails halfway through?
Most failures happen during the download step (step 4). If this occurs, reconnect to WiFi, restart your new iPhone, and try again using the same activation code or QR code. Providers typically allow 2–3 free attempts. If you've exceeded that, contact customer support—most will reset your download counter at no charge.
Do I lose my data allowance when I transfer?
No. Your data balance, remaining days, and plan terms stay exactly the same. Only the device changes. If you had 2GB left on your esimiphone.com plan, that 2GB transfers with you.
Can I reactivate an old eSIM profile I removed?
Not the same profile. Once removed, it's gone permanently. However, you can request a fresh download link from your provider (often free) and activate that on any compatible iPhone.
Should I keep my old carrier SIM in my new iPhone as a backup?
Only if you're at home and want domestic fallback coverage. For travel, carrying two SIMs complicates call/SMS routing. Instead, transfer or buy a fresh eSIM, and trust that the plan's network coverage is sufficient. If network coverage fails, WiFi calling via WhatsApp, Telegram, or Messenger is your backup.
Final Recommendation
eSIM transfer is straightforward and safe if you follow the steps in order: save your code, remove from old phone, download on new phone. The whole process takes under 10 minutes. However, most travelers don't need to transfer. Buying a fresh eSIM plan on your new iPhone is often simpler, cheaper (you're only out $10–$15), and removes the risk of activation code loss or provider re-download limits.
If you're mid-trip with an active plan that has meaningful balance remaining, or if you need zero-second downtime for work calls, transfer makes sense. Otherwise, treat it as a last-resort option and just buy new. Either way, esimiphone.com's straightforward QR-code activation and responsive support make it a good option for most travelers.
