Your SIM card, Calisero's platform
Read the guideReceived SMS forwarded to your account
The replies that reach the gateway's SIM are forwarded to Calisero with their sender and time, so the conversation stays in one place.
Nothing lost on the way
Read the guideA queue that survives restarts
Messages and delivery reports wait in a local queue and are confirmed one by one, so a lost connection, a closed app or a restarted phone loses nothing.
Daily limit and pause between SMS
The phone keeps to the limit you set and waits between messages even when more arrive at once, which protects the SIM card from being blocked by the carrier.
Statuses, reports and route
Every message has its route — received, sent to the carrier, delivered, reported — and the app adds up the day, the week or the month, failure reasons included.
Connection watched all the time
The app keeps a secure connection to the server, reconnects by itself and warns you when a permission is revoked or the server cannot be reached.
Price at launch
€0.01 / SMS
Per SMS sent through your phone, excluding VAT.
Device setup is free.
Sending from the SIM card also uses your plan with the carrier.
What you need
- An Android phone, version 8.0 or later
- An active SIM card whose plan includes SMS
- Internet, over Wi-Fi or mobile data
- The phone kept on, ideally on its charger
- A Calisero account
Carriers may block a SIM card that sends too many messages in a short time: keep the daily limit within your plan and use the gateway for transactional messages, the way the terms describe them.
