SM PD Address How TO

What is SM-DP+ address?

SM-DP stands for Subscription Management Root-Discovery Service and is used to connect consumer eSIM devices to a mobile network of the user’s choice. 

This address is needed to retrieve the final eSIM profile produced by the network operator for your specific line and device. You may then download and use this profile to quickly get your eSIM running and connected to the carrier’s network.

While most devices automatically download the needed profiles as soon as you input your eSIM details, SM-DP addresses come in helpful if devices can’t find the required settings and must manually download them, especially when it comes to setting up eSIM connections on iPhones.

Finding Your SM-DP Address

There are two main ways of finding your SM-DP address

1: Scan the code on the activation voucher

When you apply for an eSIM, you will usually receive a little activation voucher with all of the information you need to get your SIM up and running. This often contains a QR code that leads to your SM-DP address, which was used to obtain the final eSIM profile.

2: Contact your SpeedTalk Mobile

If you didn’t receive an activation voucher, or if it didn’t include a QR code or another way to obtain your SM-DP address, your best chance is to contact your network operator and allow them walk you through the process.

SM-DP + Address and how to find it

Simply switch on the device for the very first time, as well as the eSIM data (which matches your new smartphone membership that you just acquired) will be transferred over the airwaves automatically and instantly. Before you can even begin to understand the technicalities of an SM-DP+, you must first look into the elements that make an eSIM structure. So, here we go:

  • The safe box for the eSIM Information is called eUICC. It is found inside the device itself.
  • A user’s membership information, as well as their network preferences, are stored in the eSIM profile. Thanks to this, they can connect to the proper mobile network with ease.
  • All eSIM profiles are saved on the Subscription Manager Data Preparation system, which can be found on every carrier. All the data is securely downloaded to the eUICC using this system. After being set up, an alert is sent to the SM-DP+, and now, an eSIM account can be created.

How To Add & Activate an eSIM Line on Your phone

This year’s iPhone models have all been capable of supporting dual SIM, however only the real nano-SIM may be used with iOS 12. With iOS 12.1 and later, you may use your iPhone XS, XR, or XS Max with both a personal and business plan.

Because iPhones have never had a digital eSIM before, the process of setting it can be a little confusing. A dual-SIM iPhone XS, XS Max, or XR is definitely required. To utilize eSIM on the aforementioned devices, your computer must first have iOS 12.1 or later installed.

You’ll need an unlocked iPhone XS, XS Max, or XR if you wish to utilize two different networks at the same time. Otherwise, you’ll have to continue with your current carrier.

In the United States, only AT&T and Verizon Wireless now allow iPhone eSIM; SpeedTalk Mobile will follow suit soon. Sprint has also said that they want to implement eSIM, although no precise timeframe has been provided.

If your first active line is Sprint or Verizon Wireless, the second SIM will not operate with another CDMA account. Apple has verified this. As long as your iPhone is unlocked, you’ll require a GSM-based backup plan from SpeedTalk Mobile. Unlocked iPhones may be purchased via Apple, Verizon, and, in most circumstances anywhere on the internet.

Multiple eSIM Plans Are Supported

On your newer iPhone model, you can only use one of your two cellular plans at a time while making or receiving a call. If you receive another call from the other plan, no attempt will be made to connect you; instead, the call will go to voicemail. Keep this in mind as a result.

Keep in mind that if you have several eSIM plans, only one of them will operate at any one moment. This implies that unless you explicitly switch from your current eSIM plan to another, the other plans will be unreachable.

Activating Another Line on the eSIM

To add a new cellular service to your new iPhone XS, XR, or XS Max, utilize your carrier’s QR code, the carrier’s app, or manually enter the information.

To make traveling with a nano-SIM easier, we recommend contacting SpeedAtlk Mobile beforehand to transfer your nano-SIM account. However, it is feasible to enable a second or third line on the eSIM itself.

  • Nano SIM: The smallest SIM is called Nano and is just 8.8 x 12.3mm. If you have a newer generation phone, like iPhone 5 and above, you would use the nano-sized SIM.

All SIM cards from SpeedTalk Mobile are pre-cut, allowing you to select the size you want. Simply push lightly along the perforated line of the desired size, and your SIM card is sliced to the proper size!

Activating A New iPhone SIM Card

After you’ve properly inserted the sim card into the slot, you’ll need to unlock the sim card on your iPhone by following the steps below.

  • To begin, download and install the SpeedTalk App on your phone or computer. However, before you download the App, make sure it’s compatible with your device’s operating system.
  • If you’ve confirmed that, go to the app store or play store and look for the SpeedTalk Mobile App. Accept the application’s terms and conditions before moving on to the next stage of downloading it.

  • You must first contact SpeedTalk Mobile, which is normally the first step in the sim card activation process.
  • You can use your smartwatch to call any mobile network service provider and request a new SIM Card connection. Then, on your mobile, copy and paste the service provider’s URL.
  • After the browser has opened, continue by entering the SIM Card’s information.
  • Accept the terms and conditions after you’ve finished filling out the form.
  • On the next tab, you can enter 6 OTP digits, which will be sent to your computer.
  • Once you’ve entered the numbers, you’re good to go. Since some IPhones need a restart, complete the process by restarting the device.

The transfer process will take part once you have received a SIM card in the mail from SpeedTalk and ready to activate your service with us. We will ask you for your account # and password from your current carrier. Phone number must be active with the current carrier to ensure the transfer of your number to SpeedTalk network.

Keep in mind that there are exceptions to this rule, but it will never be because of SpeedTalk. Your phone will have to be in good standing with your current or past carrier. You will also have to purchase one of our plans first and you should start the transfer process with SpeedTalk prior to your cancellation with your current carrier. It’s very important that you do not cancel your account with your current carrier before the transferring process is completed.

A SIM card is an integrated circuit intended to securely store the international mobile subscriber identity number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices

a SIM (Subscriber Identity Module) card is a tiny, portable memory chip that stores information about you as a cell phone user. On it, there’s a seventeen-digit code that designates its country code of origin, the system carrier (such as AT&T or Verizon), and a unique user ID.

You may wonder, “Who cares about this code?” A valid question and guess what: phone carriers do. It’s how they attribute cell phone bills and charge us.

Above all else, SIM cards are super handy because they can be easily transferred from one device to another. Just like in my opening story, all that you’d need to do is take it out of one phone and slip it into the new one. By making the switch, most (if not all) of your contacts and personal settings will transfer with it, making life all the easier.

SIM cards were introduced all the way back in 1991. The first SIM card was about the size of a credit card. Since then, there have been several updates and iterations, making them smaller and smaller.

This evolution closely aligns with the history of the GSM (Global System of Mobile Communications) mobile network. Developed to describe protocols for second generation (2G) (3G) (4G) AND (5G) cellular networks, the GSM today stands as the default global standard for mobile communications.

SIM cards are a crucial part of GSM networks, storing user information required for authentication. Ultimately, this allows both your phone to connect with a GSM network and GSM networks to track your phone usage (specifically, your minutes, texts, data usage, etc), giving carriers the information to send you an accurate phone bill.

GSM is the standard network in America, Europe, Asia, Africa, and most other places. Interestingly, besides GSM, the United States has an additional network called CDMA (Code Division Multiple Access) that is used by carriers such as Verizon and Sprint. Phones on the GSM or CDMA network can use any carrier’s network, lowering the costs for the carriers and its users.

When it comes to your phone’s connection with either network, SIM cards are essentially the brain of your device.

A SIM Card is a chip that all devices carry. The chip that communicates with our network.

There are 3 three basic sizes of SIM card: the standard, the micro, nano.

Of th3 3 three, the Standard is the original SIM and the largest. Today, these are mainly used on older phones.

The Micro SIM card is essentially a standard SIM card with the extra plastic around the circuit board trimmed off.

A trimmed version of the Micro, the Nano is the smallest and used on today’s iPhones. Although minuscule compared to prior versions, the Nano still holds the same amount of data as earlier SIM cards.


When skimming the evolution of the SIM card, you likely noticed that they’ve become much smaller. But prior to the launch of the iPhone 4 in 2010, we really only had one SIM card size. Introduced in ‘96, it was the standard used in every phone and it made the GSM folks happy. Essentially, it was your entire phone on a card. It made things simple. If you wanted a new phone, all you’d need to do was take that SIM out, pop it into any phone and suddenly your phone number would be transferred to the new device. For over a decade, this was the standard, which made switching phones a breeze. Now? Not so much.


Enter Apple. Wanting to save precious room for its newest generation of smartphones, Apple switched from using the standard Mini-SIM to the Micro-SIM once the iPhone 4 hit shelves.

Surprisingly, the Micro-SIM wasn’t some new flashy SIM developed for the latest iPhone. Believe it or not, it was first introduced in 2003.

Back then, its purpose was clear: if a device was too small to fit a mini-SIM, you’d have to use the micro-SIM. In addition, the micro-SIM was designed for backward compatibility, meaning it can work with input generated by an older version of the SIM (such as the Mini-SIM).

In addition, despite its smaller size, the micro’s performance wasn’t impacted at all, as chip’s contact area remained the same. It turned out to be scaled down – the card only needed its excess plastic to be cut from it.

When Apple released the iPhone 4 with the micro-SIM, it became the standard for most smartphones. Samsung, Nokia, and HTC are just a few of the manufacturers that adopted the new Micro-SIM. During this time, several upgrading to the iPhone 4 opted to use an adapter to get their SIM cards cut down to Micro’s, as well. 


If you thought Apple was done using smaller SIM cards, think again. Perhaps Apple was peeved they had to use a SIM card from 2003 on the shiny new iPhone 4. Maybe they just wanted to stay ahead of the curve and throw competitors off their trail.

In any case, the launch of the iPhone 5 prompted the public to realize there was a new SIM in town: the Nano-SIM. This choice to go small made life pretty difficult for users. Anyone upgrading to an iPhone 5 or switching from Android now had to get a new SIM card or an adapter.

Fortunately, most smartphones released since 2014 (both iOS and Android) now support Nano SIM card technology as the standard. Still, it’s sad to see a card that small take over, as it was always much easier changing phones with the Standard SIM compared to the Nano.

As a product of the 1990’s, it’s amazing to consider the SIM card’s evolution, especially when compared to how fast other technologies of the era morphed and died out as newer solutions were innovated. As a link tying together the subscriber’s phone data with their network, the SIM card’s purpose has always been clear – but it will be interesting to watch what another two decades do for the future of this purpose and the SIM card itself.

Inserting or removing a SIM card is an easy process once you determine where it is stored on your phone. Depending on the type of phone, it could be placed behind the battery. In that case, you will have to open the back panel. For other phones, the SIM cards can be found on the side of the phone.

Removing the SIM card is simple if you have the right tool. Depending on what kind of phone you have, you can easily pop it out of the slot with a paperclip or the edge of something like a credit card. There are some SIM cards that are in easier spots that can slide out with the tip of your finger.

Is installing the SIM card hard?

Not at all, it takes about ten seconds. Take a look at this example of someone placing a SIM card in a phone.



If you are not sure how to insert the SIM card, look up your phone manufacturer’s instructions online or watch a video on how to easily replace the card in the right slot.


Yes, SpeedTalk will never deny you of service but your carrier has to unlock your phone for you to be able to use any other wireless provider. Please check with your current carrier to make sure you’re out of contract and the phone is in good standing.
