Direct SMS Gateway API Needed

Job ID: 39707614

Budget: ₹12,500 – ₹37,500 INR

I'm seeking a direct SMS Gateway API provider (not Twilio, Telnyx, Plivo, Vonage, etc.) for reliable SMS routes to the USA.

The API should support:
- Bulk SMS sending (marketing + alerts)
- High delivery rate to US carriers (AT&T, T-Mobile, Verizon, etc.)
- Real-time delivery reports (DLR)
- Simple HTTP/JSON or SMPP API
- Ability to handle 10K+ messages per day

Requirements:
- Must already have your own SMS Gateway / Direct API
- No resellers of Twilio/Telnyx — I am looking for a real gateway provider
- Support for Sender ID, message logs, and account balance tracking
- Must be able to show live demo/test before purchase

Ideal Skills and Experience:
- Proven experience with SMS Gateway APIs
- High reliability in message delivery
- Strong technical background in HTTP/JSON and SMPP protocols
- Ability to provide a live demo
