What is SM-DP+ Address?

Subscription Manager Data Preparation Address (SM-DP+ Address) is a unique code your device uses to connect with your carrier’s server during an eSIM setup.

This server stores your eSIM profile, which includes your phone number, carrier information, and other settings that allow your device to connect to the mobile network.

Without this address, your eSIM won’t work, and you won’t be able to make calls, send texts, or use mobile data.

The importance of the SM-DP+ Address in the eSIM activation process

The SM-DP+ Address is the key for your eSIM to connect to the carrier’s server and retrieve the necessary profile information to function.

Without this address, your eSIM cannot be activated or managed. Here’s why it matters:

Remote profile management. This address allows your carrier to remotely install or delete eSIM profiles on your device. Whether you’re setting up a new plan or removing an old one, this address ensures the correct profile gets sent to your phone without needing to swap SIM cards physically.
Security and integrity. The SM-DP+ Address helps ensure that only legitimate profiles are downloaded to your device, maintaining the integrity of the eSIM. This prevents hackers or unauthorized entities from intercepting the data or tampering with the eSIM profile.
Simplifies activation: The SM-DP+ Address automates the process of downloading and activating your eSIM profile. Instead of manual eSIM installation or additional steps, the address connects your device directly to the carrier’s server, making activation quick and seamless.

Let’s break down the step-by-step process of how the SM-DP+ Address works behind the scenes to get your device connected seamlessly.

SM-DP+ address: How does it work?

Here’s how the SM-DP+ Address works:

When you start the eSIM activation process, your device contacts the SM-DP+ server using the SM-DP+ Address. This address identifies the specific server that manages the eSIM profile linked to your carrier.
Once the connection is made, a secure channel is established between your device and the server. This ensures that the data exchanged is protected and cannot be intercepted by unauthorized parties.
The SM-DP+ server then verifies your device’s identity to confirm that it is authorized to access the eSIM profile. This additional layer of authentication prevents unauthorized devices from downloading the profile.
After successful authentication, the server sends the necessary eSIM profile to your device. This profile contains all the details needed to configure your device for the carrier’s network, including phone number and network settings.
Your device automatically configures itself with the profile information it has just received. At this stage, the eSIM is ready, and your device can now connect to the mobile network.

Where can I find the SM-DP+ Address and activation code?

Before we dive into where to find them, let’s break down what the SM-DP+ Address and Activation Code look like.

An SM-DP+ Address is typically a string of characters that directs your device to a specific server. Here’s an SM-DP+ Address example:

LPA:1$smdp.example.com$123ABC456DEF

LPA (Local Profile Assistant) indicates that the SM-DP+ is being used to locate the profile.
The “smdp.example.com” part is the domain name of the server where your eSIM profile is stored.
The final part “$123ABC456DEF” is a unique identifier or token that helps with authentication.

The eSIM Activation Code is a long alphanumeric string. It confirms that your eSIM profile can be securely downloaded to your device. For example:

1234567890ABCDEF1234567890ABCDEF

The Activation Code, used together with the SM-DP+ Address, ensures that your eSIM profile is securely downloaded and activated on your device.

Now, let’s get to the main question: where can you find these?

Email or documentation. After purchasing your eSIM, your provider often sends an email or PDF with the SM-DP+ Address and Activation Code. Be sure to check your inbox for this important information.
QR code. Many carriers include the SM-DP+ Address and Activation Code in a QR code, making setup as simple as scanning it with your phone. If everything works, you don’t even need to manually activate and enter the details.
Device settings. On certain devices, you can find the SM-DP+ Address and Activation Code under the cellular plan section in your phone’s settings. This might not always be available, but it’s worth checking.
Customer support. If you can’t locate the codes through other methods, your best bet is to contact your carrier’s customer support. They can provide the necessary details to activate your eSIM.
Customer portal. Some providers let you access your eSIM details through an online portal, including the SM-DP+ Address and Activation Code. This is a handy backup if you prefer managing everything digitally.

Holafy sends your SM-DP+ Address and Activation code in your email along with the QR code.

Once you’ve got these details, setting up your eSIM is just a matter of plugging in the info or scanning the QR code.

How to set up the SM-DP+ Address

When you scan the initial QR code provided by your carrier, your device will automatically connect to the SM-DP+ server and activate your eSIM. Easy, right?

But what if the QR code doesn’t work, or you need to input the details manually? Here’s how you can set up the SM-DP+ Address yourself.

Setting up the SM-DP+ Address on iPhone

If the QR code doesn’t work for setting up the SM-DP+ Address on your iPhone, follow these steps to enter the information manually:

Is the SM-DP+ Address the same as the SIM number?

No, the SM-DP+ Address is not the same as the SIM number, even though both are important in setting up and managing mobile connections. Let’s break down the key differences.

	SM-DP+ Address	SIM number, or Integrated Circuit Card Identification (ICCID)
What is it?	A code that connects your phone to your carrier’s server to activate and manage your eSIM.	A unique number that identifies your SIM card or eSIM on the network.
What it’s used for	Used during the eSIM setup to securely download and activate your eSIM profile.	Used by the network to recognize and register your SIM or eSIM.
Looks like	A string of characters (e.g., LPA:1$smdp.example.com$123ABC456DEF).	A long number, usually 19-20 digits (e.g., 89148000005123456789).
Where to find it	Provided by your eSIM provider	Printed on the physical SIM card or found in your phone settings for eSIM.
Changeability	Can change if switching eSIM providers or plans	Remains constant for given physical SIM cards.
Security role	Ensures secure communication between device and back-end servers	Part of the authentication process for network access

Here’s how you can find your SIM number or ICCID:

For Android: Settings > About Phone/About Device > Status/SIM Card Status > Scroll down to find ICCID
For iPhone: Settings > General > About > Scroll down to find ICCID
