How to activate an eSIM on iPhone: a practical step-by-step guide
Activating an eSIM on iPhone is a simple process, but it is worth following a few steps carefully to avoid issues, especially if you are about to travel. An eSIM is a digital SIM built into your phone: it does not need to be physically inserted and can be configured directly from iOS settings.
Before you begin, check three essential things:
Ever thought about leaving for Congo - Kinshasa?
eSIM from €8.38 · activated in 60 seconds.
- your iPhone must be compatible with eSIM - the device must be updated to a recent version of iOS - the phone must not be locked to a carrier
You will also need a stable internet connection, either via Wi‑Fi or mobile data, to complete the activation.
The most common way to activate an eSIM on iPhone is by using a QR code. After purchasing the plan, open the Camera app or go directly to Settings > Cellular > Add eSIM. Scan the QR code you received and wait for the iPhone to recognize the mobile plan.

At this point, several setup screens will appear. You will be asked to confirm adding the plan and assign it a label, such as “Travel,” “Work,” or “Data.” Giving the line a clear name is useful if you also use your main SIM.
After adding it, check these settings:
- default line for calls and messages - line to use for mobile data - “Allow Cellular Data Switching” option, to be enabled or disabled depending on your needs - data roaming, often required to use an eSIM abroad
If your plan is data-only, you can keep your physical SIM or main line for calls and SMS, using the eSIM only for browsing. This is a common setup for travelers.
In some cases, activation does not use a QR code but manual entry of the details. The path is the same: Settings > Cellular > Add eSIM > Enter Details Manually. You will need the information provided by the carrier, such as the SM-DP+ address and activation code.
Once the process is complete, check that the new line is active and that signal bars appear. To be safe, do a test by opening a website or an app that requires internet. If it does not work, check roaming, the APN if required, and available coverage.
With a SIMAMMA eSIM, activation on iPhone usually takes less than a minute. The practical advice is to install it before you leave, so that when you arrive you only need to select the correct line and start using your connection.
