Gocabbi turns any Android handset into an SMS gateway for your software. Pair the phone once, then send from your website, your app or a script — through your own SIM, at your own operator's rate. No aggregator, no sender-ID paperwork, no per-message markup.
Subscriptions secured by trusted gateways
Six steps, and you only ever do the first three once.
Not a bulk-SMS reseller. The gateway you own.
One POST sends a message; one GET tells you what happened to it. Keys are scoped, rate limited and revocable one at a time, retries are idempotent so a timeout never sends twice, and the documentation inside your panel already has your own base URL and device id filled in.
One key per app. Stored hashed, shown once, revoked on its own.
Schedule a campaign for 9am. It goes at 9am, in your timezone.
Pick the handset and the SIM per message. A switched-off SIM is refused, never swapped.
Signed callbacks on sent, delivered and failed. Stop polling.
Online or offline, battery, which SIMs are enabled, when it last reported in. The one question you have when a message does not arrive, answered before you ask it.
A customer says the code never came. Type their number, see the message, the time, the phone it went from and exactly why it failed.
Every business sending SMS already has a phone and a SIM. What most are buying from a provider is permission to use them.
An SMS aggregator charges you for access to a network you already have access to. The SIM in your drawer is on the same network, at the rate you already pay.
Start free with one phone. Move up when you outgrow it. Your operator still charges you what it always did, and we never add to it.
No caps, for high-volume senders.
Everything you need to know before you pair your first phone.
An Android phone with a SIM in it, and the Gocabbi app. Pair the phone by scanning a QR code from your panel, and you can send your first message from the Send screen or the API within a couple of minutes.
You pay your mobile operator exactly what you already pay them for SMS on that SIM — nothing more. Gocabbi charges a subscription for the software and adds nothing per message. If your bundle includes SMS, your marginal cost is whatever that bundle costs you.
A message is normally on the network within a second or two of the API call. It is queued, the phone is woken by a push notification, and it sends. One handset comfortably handles a few hundred messages an hour; add a second phone when you need more, or to keep transactional messages away from campaigns.
Messages stay queued and go out when it comes back, and the device list tells you it is offline before you have to guess. A message a phone picked up but never sent is returned to the queue automatically, and anything still unsent after its expiry window is marked expired rather than delivered late.
Yes. Pair as many handsets as your plan allows, and each one exposes both of its SIM slots separately. Every send names the phone and the SIM, so you decide exactly which number a message comes from. A SIM you have switched off is refused rather than quietly swapped for the other one.
You are sending SMS from your own SIM on your own account, which is what the SIM is for — but operators set their own fair-use terms, and bulk marketing traffic on a consumer plan is a common way to fall foul of them. Check your contract, use a business plan if you send in volume, and get consent before marketing. Compliance with the rules that apply to you is your responsibility, not ours.
Gocabbi is self-hosted, so your contacts, your message history and your API keys stay on your own server. Keys are stored hashed rather than in plain text, and message history is pruned on a retention period you set.
Yes. Import a CSV, group your contacts, and send to a whole group with placeholders filled in per person. Duplicate numbers are collapsed and anyone who has opted out is skipped automatically.
