🚨 Twilio charges $0.0079 per SMS. Someone just turned any old Android phone into a free SMS gateway. Unlimited messages. $0.
It's called SMS Gateway for Android.
Install it on any Android phone. It becomes a full SMS sending and receiving server with an API.
No Twilio. No MessageBird. No per-message pricing. No contracts. Just an old phone and a SIM card.
Here's what's inside this thing:
→ Send and receive SMS through a REST API from any app or service
→ Works with any Android phone running 5.0 or newer
→ End-to-end encryption. Messages are encrypted before they leave the device.
→ Multi-SIM support. Use multiple SIM cards on one phone.
→ Multi-device support. Connect multiple phones to the same account.
→ Real-time webhooks for incoming messages
→ Multipart messages with auto-splitting for long texts
→ Track delivery status of every message in real time
→ No registration required. No email. No account in local mode.
Here's the wildest part:
That old Android phone in your drawer that you haven't touched in 2 years? Install this app. Insert a SIM card. You now have your own private SMS infrastructure.
Two-factor authentication. Order confirmations. Appointment reminders. Notification alerts. All the things startups pay Twilio thousands a month for.
Free. Running on a phone you already own.
Startups spend $500 to $5,000/month on SMS APIs. This costs the price of a SIM card.
