GSM 03.48
GSM 03.48 is a special set of rules that mobile phones use to talk to each other when sending text messages. It's like following a recipe when you're baking a cake - you need to follow certain steps in the right order to get a good result.
When you send a text message, your phone turns your message into a special code called "SMS," which stands for "Short Message Service." This code is then sent to a special place called the "SMS center." The SMS center is like a post office for text messages. It receives your message and makes sure it gets sent to the right person's phone.
GSM 03.48 helps your phone know how to turn your message into the SMS code and how to send it to the SMS center. It also helps your phone understand how to receive messages from the SMS center and turn them into readable text for you.
So basically, GSM 03.48 is like a set of rules that helps your phone talk to other phones when sending and receiving text messages.
