FAQ
Frequently asked questions
Straight answers about the gateway model, billing, and compliance.
Do I need an SMS gateway or Twilio account?
No. PulseSMS sends through your Android device using your carrier plan. You avoid per-message gateway fees; normal carrier rates and fair-use policies still apply.
What phone can act as the gateway?
We support our Android gateway app on compatible devices. That phone should stay powered, online, and have a SIM with SMS capability for the number you want to send from.
Can I use my existing business number?
Yes — the point of PulseSMS is that recipients see SMS from the number on the gateway device. Use a dedicated line or a number you're allowed to use for outreach.
How do upgrades and billing work?
Free tier includes core sending limits. Pro and Enterprise unlock higher limits and features; Pro is billed monthly via Stripe. You can change plans as your volume grows.
Is my contact data secure?
Data is stored for your workspace only. Use strong passwords, restrict team access, and follow local regulations (e.g. consent and opt-out) for your campaigns.
