Most SMS products go through a telco aggregator and need their own number, short code, or carrier deal. Kelzop doesn’t. The mobile phone you already use becomes the SMS gateway, and we add the shared inbox, audit, and workflow on top.
A small Gateway app runs in the background on each connected Android phone. It captures inbound SMS the moment they arrive, queues them locally (encrypted), and syncs them to Kelzop over HTTPS.
For outbound, it leases jobs from the cloud and sends through the device’s own SIM, so replies arrive from your real number.
Kelzop is the system of record. Every inbound message is deduplicated, threaded by sender, checked against opt-out lists, and stored against your tenant.
Outbound replies move through clear states (queued, sending, sent, delivered) with explicit handling for the rare case where the phone sends but can’t confirm.
Your team works inside one calm web inbox. Conversations are threaded by sender across every connected number. Assign, note, tag, search, and reply, all without picking up a physical phone.
The other path is to provision a dedicated short code or virtual number per business. That’s a legitimate model, and one we may add later. But for most teams already running on mobile phones, it’s overkill, slow to set up, and means asking customers to text a new number.
