🔍 What is an SMS Sender ID?
An SMS Sender ID is the name or code that appears on your customer’s phone when they receive a message. Instead of displaying a random number, your branded name shows up — such as ARUNTOURS or SUPERSHOP. This creates instant recognition, especially for businesses running promotional or transactional campaigns.

- ❌ Avoid generic or misleading terms like “SALE123” or “TESTSMS”
