In this article, Way2go will guide you on how to switch between eSIM and physical SIM on iPhone quickly and efficiently.
Benefits of switching between eSIM and physical SIM on iPhone
Switching between eSIM and physical SIM on iPhone brings significant advantages, helping users optimize their smartphone experience. Here are some key benefits to consider:
Convenience and flexibility
Easy switching: Using eSIM and physical SIM together, the iPhone allows users to conveniently manage two phone numbers on a single device, making it easier to separate work and personal calls. Users can switch between eSIM and physical SIM quickly without removing the SIM card.
Supports multiple numbers: This feature allows you to use multiple phone numbers on the same device, which is highly useful for those who need to clearly separate work and personal life. You can easily manage calls and messages from two different numbers without carrying two phones.
Cost savings when traveling
Lower roaming charges: When traveling abroad, you can use a local carrier’s eSIM to minimize international roaming costs, helping you save a significant amount of money.
Uninterrupted communication: Keep your physical SIM to continue receiving calls and messages from your primary number without interruption, which is crucial for staying in touch with family or colleagues.
Optimized connectivity and network signal
Stable connection: If one SIM encounters an issue or has weak signal, you can quickly switch to the other SIM to ensure continuous connectivity. This is particularly useful in areas with weak network coverage.
Flexible combination: The combination of eSIM and physical SIM helps maintain a more stable connection, especially when moving through different locations.
Easy carrier management and switching
Online activation: No need to visit a store to buy a physical SIM when switching to a new carrier. You can activate an eSIM online in just a few steps, saving time and effort.
Ideal for frequent changes: This is a great option for users who frequently change plans or test different carriers to find the best service for their needs.
Freeing up the physical SIM slot
Reduced risk of damage: If you only use eSIM, you may not need a physical SIM slot, reducing the risk of SIM damage or loss. This helps protect your device better.
New iPhone models: Some newer iPhone models in certain markets (such as the U.S.) have completely removed the physical SIM slot, requiring users to adapt to eSIM. This not only makes the device design more compact but also encourages users to adopt modern technology.

Common issues when switching between eSIM and physical SIM
Although the iPhone supports switching between eSIM and physical SIM, users may encounter some common issues during the process. Below are the most frequent problems and how to fix them.
If you experience no signal after switching, there could be several causes for this issue. The SIM might not be activated or could have a connection error, and it's also possible that your carrier does not support eSIM or is experiencing system issues.
Solutions:
Check Cellular Settings: Go to Settings > Cellular and ensure the SIM is enabled.
Turn Airplane Mode on for about 10 seconds, then turn it off to refresh the signal.
Restart your iPhone.
If there is still no signal, contact your carrier to check the activation status.
There are several potential causes to consider. First, the QR code or eSIM information you are using may be invalid. Additionally, your iPhone needs to be connected to the internet during the activation process; if it isn't, this could prevent successful activation. Some carriers impose limits on the number of times an eSIM can be activated on a single device, which might also lead to difficulties during the activation process.
Solutions:
Ensure your iPhone is connected to Wi-Fi or 4G/5G when activating eSIM.
Try entering the eSIM activation code manually instead of scanning the QR code.
If your old eSIM has been deactivated, contact your carrier for a new one.
Causes:
The default SIM for calls is set incorrectly.
Do Not Disturb or Call Forwarding is enabled.
Solutions:
Check the default SIM for calls in Settings > Cellular > Default Voice Line.
Review call forwarding settings and disable it if unnecessary.
Turn off Do Not Disturb mode if it is enabled.
Causes:
The iPhone is still using the old SIM for mobile data.
Allow Cellular Data Switching is not enabled when using dual SIMs.
Solutions:
Go to Settings > Cellular > Cellular Data and select the SIM you want to use for mobile data.
Enable Allow Cellular Data Switching to let the system automatically choose the SIM with the better signal.
Ensure the SIM has an active mobile data plan from the carrier.
Causes:
iMessage and FaceTime have not updated the new phone number.
The carrier has not activated the phone number on iMessage.
Solutions:
Go to Settings > Messages > Send & Receive and check if the phone number is correct.
Turn iMessage & FaceTime off and on again.
Restart your iPhone and wait 5-10 minutes for Apple to verify your phone number.
