An SM-DP+ address is the specific server URL your phone connects to when downloading an eSIM profile.
Most travelers never see it because scanning a QR code handles everything automatically. However, if your camera cannot scan the code, due to glare, a small printout, or installing on a second device, you can enter the SM-DP+ address by hand.
This guide explains what an SM-DP+ address is, how it works, where to find yours, and how to enter it manually on iPhone, Samsung Galaxy, and Google Pixel devices.

SM-DP+, standing for Subscription Manager Data Preparation Plus, is a technology used in mobile networks to securely manage and activate SIM cards (or eSIMs) for your mobile devices, such as smartphones or tablets.
It is a secure server defined by GSMA standards that prepares and delivers your eSIM network settings to your phone over the internet.
When you set up an eSIM manually, your phone sends your activation code to this address to request and download your specific profile.
Here is the example of SM-DP+ address of an eSIM from Gigago.com:
SM-DP+ Address = rsp-eu.simlessly.com
Activation code: 305316A7A54A1B5605903BF03D9531
The SM-DP+ Address is part of Remote SIM Provisioning, the industry standard set by the GSMA that lets phones download a SIM profile over the internet instead of requiring a physical card. Think of it as the address your phone’s eSIM software contacts to say “here is my activation code, please send me my profile.”
When you buy a new phone or a new SIM card, the mobile network assigns a specific SM-DP+ Address to that specific SIM card. This address is like a digital location where your SIM card is registered.
In theory, the SM-DP+ Address is required to establish a secure connection with the mobile network operator. It allows the mobile network to send essential information to your SIM card or eSIM.
Without SM-DP+ Address, your device will not know where to fetch its (e)SIM profile from. This information can include things like your phone number, network settings, and data plans. By sending this information to your SIM card’s SM-DP+ Address, the mobile network ensures that your SIM card is properly activated and ready to use.
This significance is particularly important in the current circumstances where data security and cyber threats are main concerns.
Your eSIM provider sends your SM-DP+ address alongside your QR code, usually in your purchase confirmation email.
If you bought a Gigago eSIM, this email typically arrives within 3 to 5 minutes of payment. It contains:
rsp.esimprovider.com)Note: SM-DP+ addresses and activation codes are unique to your specific purchase. Always copy the exact text from your confirmation email rather than using example codes found online.
Note: Samsung’s menu names differ from iOS, so ensure you are inside the SIM Manager menu before attempting setup.
For other Android brands, look for the SIM or Mobile Network menu inside your main Settings app.
Usually, no. Manual entry is strictly a fallback method. Before entering details manually, check these quick troubleshooting steps:
The SM-DP+ address tells your phone where to go (the server location), while the activation code identifies which specific eSIM plan belongs to you on that server. You need both to complete a manual installation.
No. Most eSIM activation codes, including Gigago’s, re designed for a single installation on one device. If you delete an eSIM profile or try to transfer it to a new device using the same code, the activation will fail. Always install the eSIM directly on the phone you intend to use while traveling.
First, check for typos or extra spaces in your pasted text, as this is the most common cause of errors. Next, ensure your phone is unlocked and connected to working Wi-Fi. If it still fails, contact your provider’s support team (such as Gigago Support) for direct assistance with your profile.
An SM-DP+ address is simply a background system that connects your phone to your eSIM provider’s server.
While scanning a QR code remains the fastest installation method, knowing how to find and enter your SM-DP+ address ensures you can easily get connected if your camera ever fails to scan.
Short answer: No, if you are visiting multiple countries on a single trip, you do not need to buy a separate SIM card for every border you cross. By installing one regional or global eSIM before you depart, your phone automatically switches to a supported local network as soon as you arrive in a new […]
