Find SM-DP+ Address Android: Causes and Fixes

You buy an eSIM for your trip, open your Android settings, and hit a wall: your phone asks for an SM-DP+ address. GoMoWorld skips this headache entirely with an app-based installation—no codes, no manual entry, just instant connectivity.

Why does this problem occur?

An SM-DP+ (Subscription Manager Data Preparation) address is a secure server URL. Your Android phone uses this exact web address to locate, authenticate, and download your specific eSIM profile. Without it, your phone cannot connect to the foreign network. Some carriers also ask for your device's EID, the serial number of the built-in eSIM chip.

Most traditional eSIM providers deliver this address embedded inside a QR code. You scan the code, and the phone extracts the server URL automatically. The problem starts when you cannot scan that QR code. You might only have your phone screen available. You might have a broken camera. The QR code might be expired or invalid.

When the scan fails, your Android device defaults to a manual setup screen. It displays blank fields asking for the SM-DP+ address and an activation code. You are now stuck looking for technical server details just to get online. This is a common hurdle for travelers trying to set up their data plans at the last minute. If you are dealing with general address errors across different devices, review our guide on configuring the SM-DP+ address.

Physical SIM cards bypass this specific server issue, but they bring their own risks. You drop them, lose them, or scratch the gold contacts. If you suspect hardware damage on a physical card, check our guide on a damaged SIM card. eSIMs are safer, provided you can actually install them.

Quick fix (solves 80% of cases)

You need to find the exact server URL provided by your carrier and paste it into your Android settings.

First, open the confirmation email sent by your eSIM provider. Look for a section labeled "Manual Installation" or "Manual Setup Details". You will find a URL that typically looks like smdp.carrier.com or rsp.truphone.com. You will also see an activation code (a long string of letters and numbers).

Follow these exact steps to enter the details on your Android device:

1. Open Settings on your phone.
2. Tap Network & internet (Google Pixel) or Connections (Samsung).
3. Select SIMs or SIM Card Manager.
4. Tap Add eSIM or Add mobile plan.
5. Choose Enter details manually (usually located at the bottom of the scanning screen).
6. Paste the SM-DP+ address into the first field.
7. Paste the activation code into the second field.
8. Leave the confirmation code blank unless your provider explicitly gave you one.

Once you tap save, your phone will attempt to download the profile. If the profile fails to download or your phone refuses to recognize the new plan, you might be facing a deeper issue. Read about the “no SIM available” error for next steps.

Advanced solutions

If you entered the SM-DP+ address correctly and the installation still fails, you have a network or device block.

Check your Wi-Fi connection. Your Android phone must have an active internet connection to reach the SM-DP+ server and download the eSIM profile. Airport Wi-Fi networks often block the specific ports required for eSIM downloads. Disconnect from the public network. Connect to a secure, private Wi-Fi network or use a friend's mobile hotspot.

Verify your phone is unlocked. A carrier-locked phone will reject any foreign SM-DP+ address. Go to Settings > Network & internet. If you see a message stating your device is restricted to a specific carrier, you cannot install a travel eSIM. You must call your home provider and request a network unlock.

Stop background data drain during setup. Sometimes, a weak Wi-Fi signal gets hijacked by background apps trying to update, causing the eSIM download to time out. Pause your heavy applications. For more details on managing data-hungry software abroad, see our guide on managing app data abroad.

Contact your provider. If the email contains no manual details, you must contact your eSIM provider's support team. Open their live chat. State clearly: "I need the SM-DP+ address and activation code for manual Android installation."

Prevention

The best way to fix an SM-DP+ address error is to never deal with one.

Standard eSIM providers rely on QR codes and manual server addresses. This introduces multiple points of failure. You need a second screen to display the code. You need a working camera to scan it. You need to copy and paste long URLs if the scan fails.

FAQ

Where is the SM-DP+ address located?

You will find the SM-DP+ address in the confirmation email or the app of your traditional eSIM provider. GoMoWorld never issues one: installation is 100% in-app. Look for a section named "Manual Installation" or "Manual Setup Details". It looks like a standard web URL.

Where to find the SM-DP+ code to activate an eSIM?

Go to your phone Settings, tap Network & internet (or Connections), and select Add eSIM. Choose the option to enter details manually. You paste the SM-DP+ address and the activation code provided by your traditional eSIM provider into the blank fields. GoMoWorld requires neither: the app installs the eSIM for you.

How to activate eSIM on an Android device?

With standard providers, you scan a QR code using your phone's camera in the network settings. With GoMoWorld, you skip the QR code entirely. You download the GoMoWorld app, purchase your plan, and the app handles the installation directly on your Android device.
