But what if one day suddenly your mobile device stops receiving SMS messages? Chances are that you might miss some important information. This is the reason you should know about SMSC and how to change the SMSC number on your mobile device.
This post is your comprehensive guide to changing the SMSC number on your Android and iOS phones. Let’s get started!
Understanding the SMSC Number
Before we dive into the process of viewing and changing SMSC number on a mobile device, it is important to understand what an SMSC is and the role it plays in the functioning of SMS messages.
What is a Short Message Service Center or SMSC?
SMSC is a short form of Short Message Service Center. You can think of SMSC as the ‘middleman’ between the sender and receiver of an SMS message. The process of SMS communication starts with the sender typing in the text and hitting the ‘Send’ button. The message leaves the originating location and is routed to the SMSC first. Upon receiving the SMS message, the SMSC validates a few things like message formatting, recipient phone number, etc. It then forwards the message to the recipient’s device. In the same manner, the incoming messages are also processed by SMSC until delivered to the recipient’s device.
However, if in case the recipient device is unavailable for any reason, the SMSC temporarily stores the message and attempts to deliver the message later. This was an overview of how an SMSC handles the routing of SMS messages. I’m sure, now you must be curious to know what is an SMSC number.
What is an SMSC Number?
An SMSC number is an identifier for an SMSC on a network. Often SMSC number is also termed as SMSC Address, SMS Center Number, or Message Center Number. An SMSC number looks like a regular phone number, for example- +1234567980. However, this number cannot be used directly for calling or texting. SMSC numbers are typically provided by your mobile network operators, depending upon your location and carrier.
Example of SMSC Number
let’s understand the format of an SMSC number using an example:
Imagine your friend’s carrier is “Carrier A” in India. Their SMSC number might look like +919876543210, where +91 is the India country code, 987 is the Carrier A identifier, and the rest is a unique identifier for their SMSC.
Characteristics of SMSC Number
Unique to MNOs
Every MNO i.e. Mobile Network Operator uses a unique SMSC number which is dedicated to route and manage SMS messages within their network.
Backend Functionality
SMSC Numbers operate behind the scenes thus acting as the backend infrastructure for SMS communication, responsible for storage, routing, and delivery of text messages to recipients.
Invisibility
SMSC numbers are not directly visible or accessible to end-users during regular SMS communication. the mobile device i.e. phone of the user automatically transmits the SMSC number along with the text message content when an SMS is sent.
Used for Routing
SMSC numbers are used for routing SMS messages between mobile devices and across different networks, ensuring reliable delivery.
Reasons to Change SMSC Number
“Message Not Sent” – is this the notification you get every time you try to send an SMS message? Typically, a mobile user doesn’t need to know or change the SMSC number. However, at times, it becomes essential to change your mobile device’s SMSC number. Some of the most common reasons are:
-
Not Able to Send/Receive SMS
You type in the text and hit the send button but the message remains undelivered. Similarly, you are unable to receive messages from other mobile phone users. probably, you recently witched your phone or SIM cards which is why you can’t send or receive texts. In such situations, changing the SMSC number could resolve the issue.
-
Optimize Message Delivery
You are a frequent traveler switching between different regions and network operators and experience delays in receiving and sending messages. Altering the SMSC number to a more geographically relevant one might help in optimizing the speed and reliability of SMS message delivery in some instances.
-
Switching Carriers
Often mobile phone users change their carriers to avail of new plans, offers, and features. However, when a user shifts to a different carrier but still the mobile device uses the old SMSC number, then they might need to update it to ensure smooth delivery of SMS messages. This is because, during the transition, the SIM card changes but the mobile device still holds the old SMSC number. The mismatch in the SMSC number disrupts the routing and delivery of SMS messages.
-
International Travel
International roaming charges are often high and can add an unexpected burden to your pocket. Besides calling, SMS messaging is one area that international travelers use for communicating with their friends and family. When you are roaming, your mobile device might be connected to a local SMSC, resulting in higher charges for SMS messages. If in such situations, you can update it to your home carrier’s SMSC number to prevent higher charges.
-
Troubleshooting SMS Issues
For any other types of SMS-related issues, MNOs or device manufacturers may recommend changing the SMSC number.
