Android SMS Gateway vs Ozeki SMS Gateway

Android SMS Gateway connects a cloud panel and REST API to an Android phone and SIM so software can send and receive SMS through the mobile operator. Messages use the connected SIM’s real mobile number, and replies can return to that SIM’s inbox. Features include two-way SMS, scheduled sends, auto-replies, bulk campaigns from Excel or CSV with column-based personalization, and delivery reports when supported by the device and carrier path. MMS and USSD are available where the handset and operator support them. The HTTPS REST/JSON API has webhooks for delivery reports, inbound messages, and system events, with examples in several programming languages. Multi-device plans can route traffic among Android phones and SIMs, with failover if a device drops. The free plan includes one device, 300 SMS for the account lifetime, and 300 contacts; paid plans start at $19 a month. Customers supply the Android device, SIM, operator SMS credit, power, and internet, and carrier costs apply separately. The app requires Android 5.0 or newer; USSD and some other features require Android 8.0 or newer.

Ozeki SMS Gateway is on-premises software for businesses that send SMS from an office, automate messaging, or provide SMS services to customers. It sends and receives messages through modems, Android phones, and protocols including SMPP, UCP/EMI, CIMD2, OZX, HTTP/REST, SIP, and Modbus/SNMP. Routing options include least-cost and backup routing, load balancing, copying, and modifying messages. Applications can connect through REST, SOAP, JSON, WebSocket, SDKs, SQL polling, and integrations such as databases, Excel, email, FTP, and text files. The gateway can run on physical or virtual servers, cloud platforms, or an Android phone. Listed security controls include HTTPS, TLS/SSL for supported protocols, encrypted password storage, and logs that can hide phone numbers and message text. A free trial is available, but there is no free plan. Licenses are one-time purchases; listed plans range from €1,490, paid once to €79,990, paid once. SMS provider charges may also apply.
