Queue OTPs and order updates from your website — they go out through your own Android phone and SIM. No per-message gateway fees.
You keep your own number and SIM. SendLK just handles the queue and the routing.
Install the worker app, enter your pairing code, and your phone is linked to your account.
Your website calls the API with an SMS. It lands safely in your private queue.
Your phone picks up the message, sends it through your SIM, and reports back the status.
Built for OTPs and transactional updates — the messages your customers actually want.
Messages go out on your own number, so recipients see a sender they recognise. Nothing routed through a stranger's shortcode.
Your phone polls every few seconds and sends right away.
Every message shows sent or failed, with a reason.
Generate and revoke keys yourself, whenever you need.
Pair more than one device to keep sending if one is busy.
Track what you've sent this month against your plan.
Priced in rupees, pay with PayHere, and keep everything running on hardware you already own. No dollar invoices, no foreign gateway lock-in.
