Understanding Direct vs. Indirect SMS Routes: What's the Difference?

When sending an SMS to an international recipient, it traverses specific routes to reach its destination. Think of these routes like international travel plans:

Indirect SMS Route:

Much like a multi-stop flight, an indirect SMS route involves multiple transfers. An SMS can pass through four to six different transfer points before reaching the intended receiver. These numerous transfers or "hops" can degrade the quality and reliability of the message delivery due to inherent issues in each route. Any disruption, like a busy route or network connectivity issues, can cause delays or even prevent the message from being delivered. While this option might be cost-effective, it could lead to critical delays, especially if you're sending time-sensitive messages like One-Time Passwords (OTPs). If an OTP message takes too long and expires before it reaches the user, the sender incurs the cost and hassle of resending.

Direct SMS Route:

Conversely, a direct SMS route is like a non-stop flight. The message goes straight from the sender to the receiver without unnecessary detours. Although this might be a tad more expensive than indirect routes, it offers faster delivery, higher quality, and greater peace of mind. For messages containing sensitive information or those that demand immediate action, direct routes are undeniably the better choice.

Bottom Line:

While budget considerations might prompt some to choose indirect routes, it's essential to weigh the importance of timely and reliable delivery. Would you risk a vital banking OTP taking a scenic, possibly delayed route, or would you prefer a swift, straight path to ensure safety and promptness? Prioritize based on the message's urgency, sensitivity, and your commitment to user satisfaction.
