If you’ve ever tried to activate an eSIM on your phone or another device, you might have come across a technical term called the SM-DP+ address. While it may sound unfamiliar, this address plays an essential role in helping your device connect to a mobile network. It serves as a link between your eSIM and the server of the mobile carrier, allowing the correct mobile profile to be downloaded. In this article, we’ll explain what the SM-DP+ address is, why it matters during eSIM activation, and how it works in practice.

What is SM-DP+ Address?

The SM-DP+ address stands for Subscription Manager Data Preparation and it is a key part of the eSIM architecture. It refers to the server address used by your device to communicate with the remote SIM management platform during eSIM activation. When you scan a QR code or manually enter eSIM details, your device uses the SM-DP+ address to connect to the carrier’s server and securely download the necessary profile, which contains your mobile plan and identity information. [1]

This address is typically provided by your mobile operator or the eSIM provider. It is essential for linking your eSIM-enabled device with the correct mobile subscription. Without a valid SM-DP+ address, the device wouldn’t know where to request the eSIM profile, making activation impossible.

How does SM-DP+ address work?

The SM-DP+ address plays a vital role in the background of eSIM setup. It ensures your device can communicate with the subscription server to receive and activate your mobile profile. Here’s how it works step by step:

• eSIM Profile Management: The SM-DP+ server manages and stores eSIM profiles in a secure environment. It ensures that only verified systems can access or modify these profiles.

• Device Communication: When eSIM activation begins, your device contacts the SM-DP+ server through the SM-DP+ address. This address identifies your device and allows the server to verify its authenticity.

• Data Exchange: After successful verification, the server delivers the required eSIM profile data. This includes elements like your phone number, network configuration, and any linked services.

• Activation: Once the profile is received, your device installs it automatically. After configuration, the eSIM becomes active and ready for network use.

How to find the SM-DP+ address?

The SM-DP+ address is a key part of eSIM setup, and there are a few different ways you can access it depending on your provider and device.

Scanning QR Codes

Most eSIM providers deliver activation details through a QR code. This code includes the SM-DP+ address, activation code, and sometimes a confirmation code. When you scan it using your device’s camera or eSIM setup function, your phone extracts all the necessary data automatically. This method avoids manual entry and is designed to simplify activation, especially for non-technical users. If you lose the QR code, you’ll need to request the setup information again from your provider.

Contacting Your Service Provider

If you're unable to scan a QR code or need to input the SM-DP+ address manually, your best option is to contact your mobile provider directly. They can provide you with:

• The SM-DP+ server address

• An activation code (if applicable)

• Any instructions specific to your device or operating system

Some providers include this information in your account dashboard or in a setup email.

Device Settings

You may be able to view some eSIM-related details in your device settings, though the SM-DP+ address itself is not always visible after activation.

On iPhone:

Go to Settings > Cellular > Your eSIM Plan > About
Once an eSIM is installed, some device and plan details may be visible, but the SM-DP+ address does not appear in this section. It’s best to save all activation information before setup. [2]

On Android:

Navigate to Settings > Network & Internet > SIMs or Mobile Network > Advanced Settings
Depending on the model, limited eSIM-related data may be shown, but the SM-DP+ server address is typically hidden after activation. [3]

Make sure to save your eSIM activation details at the time of setup, as information like the SM-DP+ address and activation code is often hidden once installed.

How to activate eSIM with SM-DP+ address?

Activating an eSIM using the SM-DP+ address can be done in a few different ways, depending on how your mobile service provider shares the activation details. Most users complete the setup either through a mobile app, by scanning a QR code, or by entering the SM-DP+ address manually.

Using a provider’s mobile app

Some mobile carriers offer an official app that simplifies eSIM activation. After installing the app, you may be asked to log in and confirm your plan. In most cases, the app automatically handles the SM-DP+ address and eSIM profile download, so no manual input is required.

Activating with a QR code

When you receive a QR code from your provider, it includes both the SM-DP+ address and the activation code. You can scan it directly in your phone’s settings:

• Go to Settings

• Tap Cellular (iPhone) or Network & Internet > SIMs (Android)

• Choose Add eSIM or Add Cellular Plan

• Scan the QR code provided

• Complete the steps shown on screen

This method is widely supported and usually completes the activation in a few minutes.

How to set the SM-DP+ Address manually?

If you're setting up the eSIM without a QR code, your provider may give you the SM-DP+ address and activation code in text format. These can be entered manually.

Setting SM-DP+ address on Android

• Open Settings > Network & Internet > Mobile Network

• Tap the + icon or Add Carrier

• Select Enter details manually

• Enter the SM-DP+ address and activation code

• Proceed with the remaining on-screen steps

Setting SM-DP+ address on iPhone

• Go to Settings > Cellular > Add Cellular Plan

• Tap Enter Details Manually

• Fill in the SM-DP+ address and activation code

• Continue through setup, and assign a name to your eSIM plan if prompted

Frequently Asked Questions

What is an SM-DP+ address example?

Think of the SM-DP+ address as the server your phone contacts to grab its eSIM profile during setup. It’s not something you’d type into a browser, but it’s essential in the background. A real-world example would be something like gs.apple.com or rsp.truphone.com, depending on your provider. This little piece of data tells your phone exactly where to fetch your mobile plan from.

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

You can usually find the SM-DP+ address and activation code in the email you receive after purchasing an eSIM plan. Most providers also include them in your account dashboard. If you are using a QR code, these details are embedded within it and are automatically detected by your device during scanning. For manual setup, providers should give you both values in plain text.

What if my SM-DP+ code doesn’t work?

If your SM-DP+ address or activation code does not work, make sure your device is eSIM-compatible and that your internet connection is stable. Double-check the spelling and formatting of the code if you entered it manually. If the issue continues, contact your provider for support. They may need to reissue your eSIM profile or verify that your device is supported on their network.
