Installing an eSIM on your iPhone requires either a QR code scan or manual activation code entry through Cellular Settings
Before installation, verify your iPhone model supports eSIM technology and ensure your carrier provides eSIM data plans
Manual eSIM setup involves entering the SM-DP+ Address and Activation Code found in your eSIM profile credentials
After installation, configure your cellular data plan preferences and assign labels to distinguish between multiple eSIM profiles
An eSIM (embedded SIM) represents a digital alternative to traditional physical SIM cards, allowing iPhone users to activate a cellular data plan without inserting a physical card. This technology simplifies the process to install and configure mobile network services directly through your device’s settings.
Modern iPhones support eSIM technology, enabling travelers and users to switch between multiple carrier plans seamlessly. Whether you’re preparing for international travel or simply adding a secondary data plan, understanding how to properly install an eSIM on your iPhone ensures uninterrupted connectivity.
Before proceeding with eSIM installation, verify your iPhone model supports this digital sim technology. Compatible devices include iPhone XS, XR, 11, 12, 13, 14, 15, and newer models. Additionally, your carrier must offer eSIM services and provide an activation code or QR code for setup.
Ensure your device runs the latest iOS version and maintains an active internet connection during the installation process. A stable Wi-Fi connection facilitates smooth activation and prevents interruptions during cellular profile downloads.

The quickest method to install an eSIM on your iPhone involves scanning a QR code provided by your mobile carrier. This automated setup process streamlines activation by eliminating manual data entry.
1- Navigate to Settings on your iPhone
2- Select Cellular or Mobile Data
3- Tap “Add eSIM” within the SIMs section
4- Choose “Use QR Code“
5- Position your device’s camera to scan the code displayed on your provider’s documentation or screen.
After scanning, your iPhone automatically retrieves the eSIM profile information and initiates the activation sequence. Follow on-screen prompts to complete the installation, assign a label to your new cellular plan, and configure default line preferences for calls, messages, and data plan usage.
When a QR code isn’t available or scanning proves difficult, manual installation offers an alternative setup method. Your carrier provides an activation code that contains essential profile information required to install the eSIM on your iPhone.
An eSIM activation code typically follows this structure:
1$consumer.rsp.world$NNNN8888NNNNZZZZ.
The segment between the first and second dollar signs represents the SM-DP+ Address, while the portion after the second dollar sign constitutes your unique activation code.
To begin manual eSIM installation :
1- Open Settings
2- Navigate to Cellular or Mobile Data
3- Within the SIMs section, tap “Add eSIM,”
4- Select “Use QR Code.”
5- At the bottom of this screen, choose “Enter Details Manually” to access the manual entry interface.
Enter the SM-DP+ Address in the designated field—this corresponds to the middle portion of your activation code between the dollar signs. In the Activation Code field, input the final segment following the second dollar sign. Leave the Confirmation Code field empty unless specifically instructed otherwise by your carrier.
Tap “Next” in the upper corner to initiate the eSIM profile download and activation process. Your iPhone connects to the carrier network server to retrieve and install the digital sim credentials.
Once you successfully install your eSIM on iPhone, proper configuration ensures optimal functionality.
Access Cellular settings to assign custom labels distinguishing your eSIM data plan from other lines, particularly useful when managing multiple cellular profiles.
Designate default lines for voice calls, iMessage, FaceTime, and cellular data. These settings allow you to specify which line handles primary communications while utilizing secondary profiles for specific purposes like international travel or business usage.
Your iPhone can store multiple eSIM profiles simultaneously, though only one or two remain active depending on your device model. To switch between stored profiles, return to Cellular settings, select the desired eSIM, and toggle its activation status.
This flexibility enables travelers to maintain domestic and international data plan options without physical SIM card swaps. Simply activate the appropriate eSIM profile when needed and deactivate it upon return.
Adopting eSIM technology on your iPhone offers numerous advantages over traditional physical SIM cards. Instant activation eliminates waiting for physical card delivery, particularly beneficial when purchasing international data plan options from providers like Ubigi.
The ability to install and manage multiple carrier profiles directly through cellular settings simplifies switching between plans. Travelers appreciate the convenience of activating local data plan services immediately upon arrival without seeking physical SIM card retailers.
Enhanced device security results from embedded digital sim technology that cannot be physically removed or lost. Your mobile network credentials remain securely stored within your iPhone‘s hardware, reducing vulnerability to SIM card theft or damage.

After you install your eSIM on iPhone and complete initial configuration, monitor your cellular connection status to confirm successful network registration. The signal indicator should display your carrier name, verifying active service.
Test both data connectivity and voice call functionality to ensure complete activation. Access Settings > Cellular to review your data plan usage statistics and manage mobile data preferences for individual apps.
Keep your activation code documentation secure for future reference, particularly if you need to reinstall the eSIM profile after device resets or transfers. Ubigi provides comprehensive support resources to assist with any post-installation questions regarding your eSIM data plan on iPhone.
If you encounter difficulties during eSIM installation on your iPhone, several troubleshooting steps can resolve common problems. Verify your internet connection remains stable throughout the setup process, as profile downloads require consistent connectivity.
Confirm your carrier supports eSIM technology and that your account qualifies for digital sim activation. Some providers impose restrictions or require specific account types for eSIM services. Contact your mobile carrier‘s support team if activation codes fail to work.
Resolving Activation Code Errors
1- Double-check the accuracy of manually entered activation codes, ensuring no typos exist in the SM-DP+ Address or code segments. Even minor errors prevent successful eSIM installation. Request a new activation code from your carrier if persistent issues occur.
2- Restart your iPhone and attempt the installation process again after clearing temporary system caches. Update to the latest iOS version through Settings > General > Software Update to ensure compatibility with current eSIM protocols.
