Sending text messages remains one of the most popular methods of communication, even in the era of instant messengers. However, when sending an important notification or congratulation, we are often at a loss as to whether the message reached the recipient, especially if he does not respond immediately. On devices Samsung Galaxy this problem is solved at the level of system settings of the standard messaging application. The delivery reports feature allows you to receive technical confirmation that the SMS was successfully transmitted to the operator’s network and delivered to the recipient’s device.
Activating this option does not require installing third-party software or obtaining root access. All the necessary tools are already built into the shell One UI, which controls the interface of modern smartphones of the Korean brand. However, the location of the switches may vary slightly depending on the version of the operating system Android and the specific model of your gadget. In this guide, we will analyze in detail all the nuances of the setup so that you can be confident in the status of your messages.
Why do we need delivery reports and how do they work
The mechanism of delivery reports is based on cellular protocols, and not on the Internet connection. When you send an SMS, your phone transmits a packet of data to the nearest carrier tower. If the message successfully reaches the recipient's phone, the network sends back a special service signal - Delivery Report. It is this signal that is displayed to the user in the form of a checkmark or text notification “Delivered”.
It is important to understand the difference between the status “Sent” and “Delivered”. The sending status only means that your smartphone has successfully sent the message to the operator. This does not guarantee that it reached the recipient: the subscriber's phone may be turned off, be out of coverage, or have a full memory. The delivery report confirms the final stage of the message journey.
The use of this function is especially critical in business correspondence or when sending confirmation codes, where guaranteeing receipt of information is important. In personal conversations, this helps to avoid misunderstandings when the interlocutor’s silence is caused by technical network failures, and not by ignoring your message.
⚠️ Attention: Delivery reports work only in the GSM/SMS standard. If you use the Chat (RCS) function in the Google Messages application, the delivery status is displayed automatically if both subscribers have Internet access, and no separate settings are required for this.
Settings in the standard Samsung Messages application
On most smartphones Samsungreleased in recent years come pre-installed with a proprietary application, which is often indicated by a blue icon with a white bubble. This app's interface is intuitive, but the hidden settings can be confusing for inexperienced users. To activate reports, you need to delve into the options menu.
The enabling process begins by opening the application itself. Tap the Messages icon on the home screen or application menu. Next, look for the icon with three vertical dots located in the upper right corner of the screen. Clicking on this element opens a drop-down menu where we are interested in the item Settings. In new versions of the One UI shell, this item may also be indicated by a gear icon.
After going to the settings menu, scroll down the list to the “Advanced settings” section or immediately look for the “Delivery reports” item. Samsung's interface logic is designed in such a way that minor functions are often hidden in submenus so as not to clutter the main screen. The switch opposite the desired item should be active (highlighted in blue).
☑️ Checking the report settings
If you don’t find this item right away, use the search inside your phone settings. Enter the word “delivery” into the search bar at the top of the settings screen, and the system will redirect you to the desired toggle switch. This is a universal method for all models, from budget series Galaxy A to flagship Galaxy S.
Instructions for the Google Messages application
Many users prefer to replace the standard application with Google Messages, which is often offered by the system at first launch or installed independently from the Play Market store. The logic of the settings here is slightly different, since the interface follows the Material Design guidelines, and not the Samsung corporate style.
To enable the function, open the Google Messages application and click on your profile avatar or the icon with three dots in the upper right corner. In the menu that opens, select Settings. Next, go to the “General” section or immediately find the subsection related to SMS and MMS. This is where the switch is hidden Request delivery report.
It is worth noting that in the Google application, settings can be applied globally for all SIM cards or require individual settings for each slot if you have a device with two active lines. Carefully check which SIM card you are activating the function for if you are using a dual SIM.
After activation, the settings take effect immediately. There is no need to restart your phone. You can test the function by sending a test message to another number. If everything is configured correctly, a small “Delivered” message will appear under your sent message after the recipient receives the SMS.
Features of working on dual-SIM devices
Owners of smartphones with support for dual SIM cards are faced with additional setup nuances. The Android system allows you to assign different applications to different SIM cards or use one application for both lines. In the case of the standard Samsung application, delivery report settings are usually applied to all active SIM cards simultaneously.
However, when sending a message, the system always asks (or uses the default setting) which card to send the SMS from. The delivery report will only come for the line through which the message was sent. If you sent a text via SIM 1, then confirmation will only come from the operator of this SIM card.
Sometimes users are faced with a situation where reports come from only one card. This may be related to your data plan or carrier settings, rather than the phone itself. Some virtual operators or corporate plans may block the transmission of delivery signaling in order to save signal network traffic.
| Option | Samsung Standard Application | Google Messages | Third Party Clients |
|---|---|---|---|
| Menu location | Three dots -> Settings | Avatar/Dots -> Settings | Depends on the developer |
| Function name | Reports on delivery | Request a delivery report | SMS Delivery Reports |
| Dual SIM support | Global setting | Often separate | Individual |
| Visualization | Tick or text | Text under the message | Various |
Why delivery reports do not arrive: basic reasons
Even with the setting correctly enabled, you may not see the coveted “Delivered” notification. There are a number of technical reasons why this happens. The first and most common are the operating features of the operator’s network. Not all mobile operators support the transmission of delivery reports in real time or even provide this service for free.
The second reason lies in the recipient's device. If the recipient's phone is turned off, in Flight mode, or outside the network coverage area, the report will not arrive until the subscriber appears on the network. Some operators store these reports for a limited time (usually from 24 to 72 hours), after which a delivery notification will no longer be sent, even if the message finally arrives.
It is also worth considering the human factor and privacy settings. Some users deliberately disable the sending of read and delivery reports in the settings of their phones, wanting to maintain the anonymity of the fact that they received a message. In this case, your phone technically will not be able to receive confirmation since the network will not generate a response signal.
Impact of Power Saving Mode
The Power Saving Mode on Samsung may limit background data transfer for system services. If you have Hard Power Saving mode enabled, try disabling it and resending the message to see if the report arrives.
⚠️ Attention: If you send a message to a roaming number or to another operator in another country, the delivery report may not arrive due to the lack of signaling information roaming agreements between operators.
Troubleshooting and advanced settings
If you are sure that the settings are correct, the operator supports the function, but reports are still not received, try performing basic troubleshooting steps. A simple network settings reset often helps. To do this, go to Settings phone, select the section General settings, then Reset and press Reset network settings. This action will delete saved Wi-Fi access points and Bluetooth pairs, but will restore the correct cellular settings.
Another effective method is clearing the cache of the Messages application. Go to Settings -> Applications, find “Messages” in the list, go to the section Memory and click Clear cache. Do not confuse this with clearing data, as the latter action may delete your chat history if it is not synchronized with the cloud.
Also check whether receiving service SMS is blocked in the settings of your SIM card by your operator. Sometimes services such as Antispam may mistakenly filter technical data packets, considering them to be unwanted content. Contact your operator's support to make sure there are no restrictions on your tariff.
Tip: If reports are critical to your operation, try sending a test SMS to another operator's number. This will help you figure out whether the problem is in your phone or in the specifics of a specific mobile operator.
In rare cases, the problem may be related to outdated software. Make sure your version Android and firmware Samsung One UI are updated to the latest available version. Developers regularly release patches that correct errors in the operation of communication modules.
Does the inclusion of reports affect the cost of SMS?
The delivery reporting function itself is a free service from the smartphone. However, some carriers in certain plans may treat the delivery signal as a separate outgoing message or charge a small fee for the confirmation service. It is recommended to clarify this point in the tariffs of your operator, although in most modern tariffs this is free.
Is it possible to find out whether the recipient has read the message?
No, the standard SMS protocol allows you to find out only the fact that the message was delivered to the device (into the phone's memory). It is impossible to find out whether the user opened the text and read it through a regular SMS. This function is available only in instant messengers (WhatsApp, Telegram, Viber) or in the improved RCS (Chat) standard, if it is supported by both subscribers and the operator.
Why does the report arrive with a long delay?
A delay in the arrival of a delivery report usually indicates instability of the communication channel. The message may have ended up in a queue on the operator's server due to network congestion or a poor signal at the recipient. As soon as the recipient's phone stabilizes the connection with the base station, the server will send a confirmation, and you will see the report, even if several hours have passed.
Are delivery reports saved in history?
In the standard Samsung application, the delivery report is displayed directly below the text of the sent message in the form of a small inscription. It is not saved as a separate incoming message in the general conversation thread, so as not to clutter the correspondence history with technical notifications. If you delete a sent message, its delivery information will also disappear.
Is it possible to enable reports only for certain contacts?
Unfortunately, in the standard Android settings and the One UI shell there is no option to selectively enable delivery reports. The function works globally: it is either active for all outgoing SMS, or disabled completely. To implement custom reports, third-party applications with advanced functionality would be required, but their use is not always recommended for data security reasons.
