Common questions
How can text messages be free?
Texts go out through the SIM cards in your own phones, using the plan you already pay your mobile carrier for. heartbit doesn’t add a second per-message charge on top.
Do I need special hardware?
No. Any Android phone running Android 8.0 or later with a working SIM card will do. Learn about gateways.
Can I use my existing business number?
Yes. Put the SIM with your business number into a gateway phone and texts to that number arrive in heartbit.
Does it work with iPhone?
Gateways need to be Android phones, because iPhones don’t allow apps to send texts on your behalf. Your team can use heartbit from any computer or phone browser.
