EasySendSMS supports multiple integration protocols to fit any architecture:

Send hundreds to millions of SMS messages globally with a single request. Our intelligent routing engine delivers messages with high speed and high deliverability across 200+ countries and 1,100+ mobile networks. Set custom sender names, schedule messages, and track delivery in real time.

Priority routing ensures time-sensitive messages like one-time passwords (OTP), two-factor authentication (2FA) codes, order confirmations, and system alerts are delivered instantly. Our infrastructure is optimized for low-latency, high-reliability delivery.

Verify the live status of any mobile number before sending. Our HLR Lookup API returns subscriber status, roaming information, ported network data, MCC/MNC codes, and more. Clean your contact lists, reduce failed deliveries, and save on messaging costs.

Our Number Validation service checks whether a phone number is correctly formatted, identifies the country and original network, and determines if it is a mobile or landline number. Validate up to 30 numbers per request.

Rent dedicated virtual numbers to send and receive SMS. Enable two-way conversations with your customers for support, feedback, interactive campaigns, and opt-out management.

Receive real-time delivery status callbacks pushed directly to your server. Track message states (Delivered, Expired, Undelivered) and integrate delivery data into your CRM, analytics, or billing systems.
