Activating the phone is equivalent to Updating Profile in Sprint. It will update the MSN MSID as well as the data information and will also update the phone number.  Over the air reprogramming became available after an earlier Sprint made the capability active. After a phone has been added to a customer’s account and provisioned in the Sprint system, the information on the phone itself needs to be updated.

Your device will connect to Sprint’s data network as soon as you select “Update Profile,” at which point it will make a request to the OMADM (open mobile alliance device manager).

In response, the OMADM will push a provXML file to your phone, which will contain your MDN, MSID, username, primary and secondary HA ip addresses, HA password, and AAA password. There are probably a few other variables concerning WiMAX and other technologies like it, but I am not familiar with what they are.

Your phone will use this information to authenticate itself on the Sprint network in order to send and receive voice and data communications. In the event that any of these variables were to be inaccurate, you would experience difficulties in placing or receiving calls as well as connecting to data.

In this instance, “Update PRL” transmits your Preferred Roaming List to the OMADM in order to make the same kind of request that it would normally make. This is essentially a list of the identifiers and capabilities of each tower.

When towers are erected or upgraded, as well as when roaming contracts with other carriers are altered, carriers will frequently release new PRLs. Because they have to pay the respective business for your airtime, it is to their advantage to ensure that you are roaming on the tower that charges the least amount of money. This saves them a significant amount of money.


What is PRL?

This refers to the list of service providers that are kept in a CDMA mobile phone while the phone is roaming in an area that is not its home area. The PRL should be automatically updated by the carrier; however, when there are problems with the customer’s connection when roaming, the customer can manually reset and update the PRL themselves.

In Restrictive Mode, the phone will only acquire networks that are in the Preferred Register List (PRL). If all PRL networks are unavailable, the phone will automatically acquire a network that is not on the list when it is set to the permissive mode.


How to Update PRL on Sprint?

Updating your Sprint phone’s preferred roaming list (PRL) will help boost signal strength on and off the Sprint network, reduce dropped calls, and help with Web connection troubles. It can also be useful if your phone is unable to make calls while roaming off the network. Updates can be performed immediately from the handset of your phone. The instructions may differ somewhat based on the model of your phone:

Step 1: On your Sprint phone’s home screen, press the “Menu” button. Select “Settings” and then select the “Menu” button. Scroll down to “Version” and select “Phone Info.” Press the “Menu” button. Scroll down to the “PRL” section and click “Update.” Wait for the update to finish.

Step 2: To return to the phone’s home screen, press the “End” key.

Select “General” from the “Settings” menu. Tap “Update PRL” and wait for the update to finish. If no update is available, press the “Menu/OK” key. To return to the phone’s home screen, press the “End” phone key.

Step 3: From the phone’s home screen, tap the green “Phone” button. From the “Applications” menu, select “Preferences.” Wait for the update to complete before tapping “Update PRL.” To return to the phone’s home screen, press the red “End” button.


What Is OMADM?

OMA Device Management (DM), often known as OMADM or just OMA Device Management, is a protocol that was developed for the purpose of device management through the collaborative efforts of the Device Management, Open Mobile Alliance (OMA), and the Data Synchronization working groups (DS). The HTTPS protocol is used to establish connection with the server when using the OMA-DM protocol.

In the form of the message payload, this takes use of the most recent and most up-to-date version of OMA-DM, which is 1.2.1. The most recent update and specification was published in June 2008, and as of right now, it is the version of OMA-DM =1.2.1 that has received the highest level of acceptance and approval.

What Are The OMADM Specifications?

PDAs, mobile phones, and tablets all had their own individual specifications for OMA DM that were established and made public in the year 2003. The concept was developed primarily for constrained devices, which have restricted bandwidths but are nevertheless capable of M2M communication via a variety of protocols.

These protocols include WAP, HTTP, and SMS. This can be used in conjunction with any of the following functions performed by devices:

Support provisioning

Whenever a new system is installed, any device should immediately register itself along with the associated metadata. This should happen automatically. Whenever one of these registrations is carried out, the system will supply an identity as well as credentials for it.


Device management (DM) services often offer either the direct application of newly configured devices or the broadcasting of newly configured devices in order to perform a mass configuration update. In addition to that, it is responsible for managing any dependencies that are contained within the configuration.

Firmware updates

This involves the significance of installing new and updated software as well as the need for flaws to be fixed in the system. Both application and system software are included in this category.

Fault management

Device management services have a number of responsibilities, one of which is to maintain a record of all device logs and metadata. A service could, for instance, monitor the firmware version, device capabilities, the typical location of the device, its current condition, and its unique identifier.

This information, together with connectivity logs and error messages, is frequently made available for remote debugging by services for device management. This data can be accessed by dashboards or APIs. The status and logs can also be used to generate alerts, for instance, if the device has not given out any data for a specific amount of time. This can be done if the device has been running for a certain amount of time.


The identities of the devices can more easily be determined with the assistance of authentication services. During the process of provisioning, the device will use the identity that was just created.

This assures that whenever there is external communication with other apps, devices, or services, the other party will be able to have peace of mind knowing that the device is originating from a reliable and genuine source.


How Does OMADM Function?

After the client and the server have successfully established a reliable line of communication with one another, a string of messages will start to be conducted and then exchanged in order to complete the particular task that was provided by the device manager. However, OMA-DM has the ability to divert a few message alerts away from the normal flow of events; however, in the long run, this must be started by either the client or the server.

The primary purpose of these warning messages is to address any flaws, problems, or anomalous terminations that may have occurred.

Before the beginning of the session, the client and the server will negotiate quite a few factors that are immediately connected to the communication that will take place during the session. This occurs inside the confines of maximum messages.

Next, the OMA-DM protocol will break down a huge item of instructions into a series of smaller and smaller chunks. As a consequence of the non-specification of the since error recovery timeouts, there is a distinction between the various operations that have been carried out.

In addition, while the conversation continues, multiple packages, each of which is composed of a number of individual messages, are being traded.

Every message contains a variety of different directives. After that, the server will provide the command, at which point the client will put those commands into action and then offer the result in the form of a reply message.


What Is Sprint OMADM?

The Sprint OMADM is a brand-new design for a modem, and it enables over-the-provisioning in addition to being an internet-based modem. Once a reputable modem has been properly registered within the Sprint network, the OMA-DM provided device will become functional immediately after this step has been completed.

This is due to the fact that the new OMA-DM is network-oriented in a very specific way. Following successful completion of the registration, the modem will be able to perform a hands-free activation on its own.

It is essential to keep in mind that in order to avoid interrupting the activation process at this stage, no direct command(s) should be issued to the modem. Resetting the modem or turning it off and on again is what I mean by this. It is recommended that these actions be carried out after the activation procedure has been finished in its entirety.

How to Activate Sprint for OMA-DM?

To begin, you will need to initiate the process of setting up your account by contacting a Sprint customer care agent. It is imperative that this information be made public in advance of that date;

  • Your billing address
  • Your modem’s Mobile Equipment Identification (MEID), often known as IMEI. This information is printed on the label of the modem.

The Sprint agent you contacted will first guide you through the process of picking your service plan, after which they will supply you with the following information:

  • Your code for the Service Programming ( SPC)
  • Your device Mobile ID Number (MIN or MSID)
  • Your equipment’s unique phone number (MDN)

Device management (DM) services assist in automating the management of Sprint devices for the duration of the lifecycle of those devices. Authentication, configuration, provisioning, monitoring, maintenance activities, and eventually decommissioning are all part of this process.

To put it another way, in order to have a Sprint solution that is compatible, device management is an essential component for it.
