Moving an eSIM from an Android phone to a new iPhone normally runs through your carrier rather than between the two handsets, because Apple’s Quick Transfer moves lines between iPhones and Android’s transfer tools move lines between Android devices. The carrier reissue route works on every network and every device pair, keeps your number, and takes a few minutes.

This guide gives the exact sequence, the Samsung specific details, what to do with a travel plan, and how to avoid the gap where you have no working line at all.

In this guide:

What you need before you start

Five things, and gathering them first turns this into a five minute job.

  • The new iPhone set up and on Wi Fi. Installing an eSIM needs an internet connection, and it cannot be the line you are moving.
  • The iPhone’s IMEI and EID, from Settings, General, About. Carriers ask for one or both. Our glossary explains what an EID and an IMEI identify.
  • Access to your carrier account, ideally their app, which is usually the fastest route.
  • The old Android phone still working. It is your fallback and your route to support.
  • Time when being briefly unreachable is fine. There is a short gap during the switch.

The transfer sequence

  1. Finish setting up the iPhone and connect it to Wi Fi.
  2. Request an eSIM for the new device from your carrier, giving them the iPhone’s IMEI and EID.
  3. Receive the QR code or activation link. Display the code on a laptop or print it, because a phone cannot scan its own screen.
  4. On the iPhone, go to Settings, Cellular, then Add eSIM and scan the code, or use the option to enter details manually. Apple documents the current flow in its eSIM setup guide.
  5. Test the new line: a call, a text, and a page loaded over mobile data with Wi Fi switched off.
  6. Only then remove the old profile from the Android phone, if the carrier has not already deactivated it.

Step five matters more than it looks. A line that registers is not necessarily a line that passes data, and finding out later is worse than finding out now.

Coming from a Samsung Galaxy

The Samsung side of the move is mostly about not breaking anything before the new line exists.

Leave the Galaxy’s profile in place while you request and install the new one. When the carrier deactivates the old profile, the Galaxy will simply lose service on that line, which is the expected outcome rather than a fault. Only delete it from Settings, Connections, SIM manager afterwards, and only if the carrier asks you to.

Samsung eSIM support varies by region and variant, which occasionally matters here too: if you are keeping the Galaxy as a second device and want to put a different line on it later, check it against Samsung’s Galaxy eSIM compatibility page first.

If you are also carrying a travel plan on the Galaxy, read the travel section below before touching either profile.

Setting up the line on the iPhone

Once the profile installs, three settings decide whether it behaves the way you expect.

  • Label the line something meaningful rather than leaving the default. If you run two lines, clear names prevent the wrong one carrying data.
  • Choose the default data line. If your new iPhone holds both a home line and a travel plan, set data to the one you intend to pay for and turn off automatic switching.
  • Set data roaming deliberately. Off for the home line when abroad, on for a travel line, which is the arrangement described in the dual SIM travel setup guide.

If the line installs but shows no service, the eSIM not provisioned guide covers the fixes in order, and eSIM installed but no data covers the case where the line registers but nothing loads.

Travel eSIMs do not transfer

A prepaid travel plan is not a carrier line and the rules above do not apply to it. Travel profiles are bound to the device that downloaded them and their activation codes are single use, so there is nothing to rescan on the iPhone.

Contact the provider with your order reference and ask whether they will reissue for the new device. Many will, once, with the remaining data intact. If they cannot, buying a small plan for the new phone is the practical answer, especially mid trip when waiting is not an option. Sizing a short replacement without overpaying is covered in the cheapest eSIM plan guide, and plans by country are on the destinations index.

The rule that protects you either way: do not delete the travel profile from the Android phone before you have asked.

If the carrier says it cannot be done

Occasionally a first line support agent says a transfer is not possible. It almost never means what it sounds like, and three follow up questions usually resolve it.

Ask whether they can issue a new eSIM for a new device, rather than asking about a transfer. Those are different operations internally, and the second one is routine on every network that supports eSIM at all.

Ask whether your plan type is eligible. Some prepaid and business accounts are excluded from self service eSIM issuance even where the network supports it generally, and the fix is a different channel rather than a different phone.

Ask for the manual activation details, meaning the SM-DP+ address and the activation code. If they can produce those, you can install the profile by typing them into the iPhone’s add eSIM screen, with no QR code needed.

If all three come back negative, the remaining routes are a store visit, where staff can usually issue a profile on the spot, or a physical SIM as a stopgap while it is sorted out.

Avoiding the gap with no service

Every carrier reissue has a moment where the old profile is dead and the new one has not registered. Usually it is a couple of minutes. Occasionally it is longer.

Four ways to make that gap harmless:

  1. Do it at home on Wi Fi, where messaging and calls still work over the internet.
  2. Do it when you are not waiting on a verification code. Banking and login codes go to your number, and during the gap nothing arrives.
  3. Keep the old phone powered and nearby until the new line passes the test in step five.
  4. Do not do it the morning you fly. A transfer that needs a support call is a bad thing to discover at an airport.

Treat the gap as planned downtime rather than a fault, and it never becomes one.

If you are moving in the other direction, our guide to transferring an eSIM from iPhone to Android covers that pair, and the general eSIM transfer guide covers same platform moves on both systems.

Putting a travel plan on the new iPhone

Once the carrier line is live on the iPhone, adding a travel data plan alongside it takes a couple of minutes and is what the second line is for.

Viasimo sells prepaid travel eSIMs for more than 190 destinations, with the price, size, validity and covered countries all shown before you pay. The QR code arrives by email within minutes and installs from Settings, Cellular with no app to download. Because it is a one off purchase, nothing renews, and because it is data only, your number stays on the carrier line while the travel plan carries the data at local prices.

Start with the USA, Europe or Japan, or compare everything on the destinations index.

When you know your destination and your dates, the eSIM plan picker puts every matching plan and price on one screen.
