Bangladesh SMS Market – Facing challenges

The SMS market in Bangladesh has been struggling lately. Operators are blocking messages across networks, which makes delivery rates drop and performance unstable. For those relying on SIM routes, it’s becoming harder and harder to keep things running smoothly.

Our team has noticed that while SIM routes are technically still active, cross‑operator filtering means reliable delivery is almost impossible. That leaves us asking: what’s the best way forward to stabilize traffic in this environment?

Is there anyone know how to deal with this, or is dirext route a better solution?

Yes, it's happening everywhere.

One issue is that many providers still rely on large SMS gateways instead of using mobile devices, which often perform better when it comes to network coverage and reliability.

If you're sending traffic through operator routes, avoid pushing 10,000 SMS all at once. Spread the traffic out over several hours or even several days, depending on the use case. Large spikes are much more likely to trigger filtering and rate limits.

I find it strange how impatient some operators are. What's the urgency in sending everything immediately? A more gradual approach generally leads to better delivery rates and fewer problems.

I still have SMS gateways sitting unused because many people overlook these basic traffic management principles.
