Android SMS Gateway vs SMSBOX

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.

SMSBOX is a cloud SaaS messaging platform for professional communication through a web dashboard or REST API. It supports bulk SMS, OTP codes, WhatsApp Business messages, voice calls, email-to-SMS, and scheduled sending, with delivery to more than 200 countries. The dashboard imports Excel contacts, applies personalization tags, schedules messages, and tracks results in real time; access is free while messages are charged per use. The API handles sending and receiving SMS, OTP verification, HLR number validation, voice messages, inbound webhooks, and delivery reports. SMSBOX lists more than 50 direct integrations and 6,000+ Zapier apps. JAAN says servers and data storage are in Belgian EU data centers under GDPR. Free test credits provide eight one-off credits for a verified number. Arbitrary-number sending costs from €0.06 per SMS. Credits last one year, and longer messages count as multiple SMS.
