Overview

Messages go out from the real mobile number on the connected SIM, and replies can return to that phone’s inbox. That can suit workflows where a controlled SIM is central to the messaging setup, but it also makes the phone and mobile operator part of the service’s operating requirements.

Alongside two-way SMS, the platform supports MMS, scheduled sending, auto-replies, and USSD when the handset and operator allow it. Delivery reports depend on the device and carrier path. Bulk campaigns can use Excel or CSV imports with personalization from spreadsheet columns, a practical option for teams managing recipient lists outside the platform.

Key features

API and webhooks: A REST/JSON API over HTTPS and webhooks cover inbound messages, delivery reports, and system events. Code examples include PHP, Python, Node.js, Java, and C#, giving developers several starting points for integration.
Multi-device routing: Multi-device plans can route traffic across Android phones and SIMs, with failover when a device drops. This helps reduce dependence on a single handset, though it does not remove the need to maintain the devices and their connections.
Security and data: The maker says it uses HTTPS, API keys, two-factor authentication, scoped tokens, session management, and security monitoring. It processes account and contact details, usage and device metadata, delivery reports, and support correspondence, and says it does not sell personal information for advertising. SOC 2 is on its roadmap; it does not currently have a completed SOC 2 Type I or Type II report.

Pricing

The Free plan costs 0.00 USD per free and includes one Android device, 300 SMS for the lifetime of the plan, and 300 contacts. That cap makes it suitable for a small evaluation, not ongoing production traffic. Demo messages append a www.sms-gateway.app footer.

Starter costs 19.00 USD per month for two Android devices and unlimited platform send volume. It is the lowest-cost paid option for a small setup, but operator SMS credit and other carrier costs remain separate. Professional costs 39.00 USD per month for five devices and unlimited platform send volume; the added device capacity may suit teams distributing traffic across several phones. Business costs 77.00 USD per month for 15 devices and unlimited platform send volume, targeting larger multi-device deployments. “Unlimited” applies to platform send volume, not the operator’s separate charges or fair-use rules.

Developer costs 50.00 USD per year, billed yearly, and includes one Android device with 25,000 SMS per year. Its annual quota makes it a lower-cost fit for a single-device integration with predictable volume, but it is less suitable for heavy or variable traffic. The Free plan includes a trial; customers must supply the Android device, SIM, operator SMS credit, power, and internet connection. Email support with a 24–48 hour response window is included on Free, Starter, and Developer; Professional has priority email support, while Business includes email and phone support.

Platforms

The service is listed for Android, API, and web. The app requires Android 5.0 or newer, while features such as USSD require Android 8.0 or newer.

Who it's for

Android SMS Gateway is a sensible fit for developers and teams sending OTPs, alerts, transactional messages, or campaigns through SIMs they control, especially when sending from a real mobile number matters. It is a weaker fit for anyone who does not want to supply and maintain Android hardware, internet access, and operator credit, or who requires a completed SOC 2 report.

Pros and cons

Pro: Messages use the connected SIM’s real number, with replies able to return to its inbox—useful when a SIM-based identity is part of the workflow.
Pro: REST/JSON API, webhooks, and multi-device routing support both software integration and traffic distribution across phones.
Con: Customers provide the handset, SIM, power, internet, and SMS credit, while carrier costs and fair-use rules apply separately.
Con: Free is capped at 300 lifetime SMS, and demo messages carry a service footer, limiting its usefulness beyond evaluation.
Con: USSD and delivery reports depend on device and carrier support, and the service has no completed SOC 2 Type I or Type II report.

Alternatives

SMS Gateway Software is the broader category directory for comparing options. Choose OpenVox SMS Gateway if Linux or self-hosted platforms are a better fit; its free version covers essential features for getting started. simhook offers a free tier capped at 30 messages a day, 500 a month, one phone, and 25 recipients per send, plus a free self-hosted whole-stack option with no limits, making it worth considering for those caps or deployment preference. Telerivet may suit a smaller initial workload with its free allowance of 50 messages per day, 50 stored contacts, and two automated services.

Bird Verify is another option. Clickatell SMS API offers pay-as-you-go outgoing messaging with destination- and message-type-dependent prices, or a Connect plan for enterprise SMS via API. Smstools charges per message for U.S.A. SMS, with no subscription and volume discounts. BulkGate has a United Kingdom pay-as-you-go rate shown excluding VAT, with rates varying by country and operator. SMSGatewayCenter is an alternative listed for web, iOS, Android, and macOS.

Verdict

Choose Android SMS Gateway if your software needs to send through SIMs you control and its API, webhooks, and multi-device plans match your workflow. The real-number sending and reply path are its clearest strengths; look elsewhere if you want to avoid managing phones and carrier costs, need a larger free allowance, or require completed SOC 2 certification.
