Switching to eSIM When You Change Phones: A Practical Guide
Just upgraded your phone and your old SIM doesn't fit? Learn how to switch to eSIM in minutes — and how to transfer your existing plan to your new device.
Should I Switch to eSIM When I Change Phones?
If you've just upgraded to a new handset and your old SIM card doesn't fit — or your new phone has no physical SIM slot at all — you're at the perfect moment to make the switch to eSIM. The transition is simpler than most people expect, and it solves the compatibility problem permanently.
An eSIM (embedded SIM) is a digital SIM card built directly into your device's hardware. Instead of slotting in a plastic card, you download a carrier profile by scanning a QR code sent to your email. Within minutes, your phone is connected to a mobile network — no store visit, no waiting for delivery.
SimForMe offers instant-activation eSIM plans sent directly to your email as a QR code. Plans for the US start from €3.44 for 1 GB/7 days, up to €19.78 for 10 GB/30 days. For the UK, plans start from €3.44, with 10 GB/30 days at €16.77. See all options at /packages/us and /packages/gb.
I Just Switched Phones and My Old SIM Doesn't Fit — What Should I Do?
This is one of the most common scenarios that drives people to eSIM. Your old nano-SIM won't fit in the new slot. Your new phone has no SIM tray at all. Or you're moving from Android to iPhone and the carrier setup is different.
The good news: switching to eSIM resolves all of these in one move.
How to switch in three steps:
- Check eSIM compatibility — Most phones released after 2018 support eSIM. Go to Settings > Mobile Data > Add eSIM to confirm.
- Buy a SimForMe plan — Choose your country and data size. Complete the purchase online. You'll receive a QR code by email within minutes.
- Activate on your new device — Open Settings > Mobile Data > Add eSIM, scan the QR code, and your connection is live.
The entire process — from purchase to being connected — typically takes under ten minutes.
Can I Transfer My Existing eSIM Plan to a New Device?
Yes, but eSIM profiles work differently from physical SIM cards. A physical SIM can be physically removed and slotted into another device. An eSIM profile is bound to a specific device and requires re-provisioning when you switch phones.
With SimForMe, the re-provisioning process is straightforward:
- Keep your original order confirmation email
- Contact SimForMe support with your order ID and the model of your new device
- We deactivate the old profile and issue a fresh QR code for your new device
- Scan the new QR code, and your plan is active again
There is no additional charge for this process. Plan validity continues from when the new QR code is first scanned.
This is one of the questions most worth preparing for before you upgrade: note your order ID before you wipe or trade in your old device.
Which iPhones and Androids Support eSIM?
iPhone:
- iPhone XS, XR, and later (2018+) all support eSIM
- iPhone 14 and later (US models) have no physical SIM slot — eSIM only
- iPhone 15 and 16 series: eSIM-only in most markets
Android:
- Google Pixel 3 and later
- Samsung Galaxy S20 and later (most flagship models)
- Most newer Motorola, OnePlus, and Huawei devices
If you're unsure, search for your device model + "eSIM support" or check your phone's settings for an "Add eSIM" option under mobile data.
How Fast Is eSIM Activation?
With SimForMe, you'll receive your QR code by email within minutes of purchase. Scanning the QR code and completing the eSIM installation takes approximately two minutes. You're fully connected shortly after — the whole process is under five minutes once you have the QR code.
This is significantly faster than waiting for a physical SIM delivery (typically 2–5 business days) or visiting a carrier store.
