Launching soon. The Calisero Gateway app is not available yet. Create an account and we will email you on launch day; this guide describes the steps from then on.
The Calisero Gateway app turns an Android phone into an SMS gateway for your account: the messages you send through Calisero — from the API or the dashboard — leave from the phone's SIM card, and the SMS that card receives come back to your account. The service and its prices are presented on the SMS Gateway page.
The app's screens are in Romanian; the labels below are given in English.
What you need
- an Android phone, version 8.0 or later;
- an active SIM card whose plan includes SMS;
- an internet connection, over Wi-Fi or mobile data;
- a Calisero account.
A dedicated phone, kept on and on its charger, works best. The gateway only sends while the phone is on and connected.
1. Install the app and sign in
Install Calisero Gateway on the phone, open it and tap Sign in. Use the same details as in the dashboard; if two-step verification is on, the app asks for the code as well.
If the dashboard is already showing the QR code, you can choose I have a QR code from the dashboard instead: the code carries the account, so no sign-in is needed.
2. Grant the permissions
The app lists the permissions with the status of each. The required ones are:
- send SMS — so messages can leave from the card;
- read received SMS — so replies reach your account;
- phone and SIM state — so the app sees the cards and the signal;
- notifications — for the gateway's permanent notification;
- no battery restrictions — so Android does not stop the app in the background.
Access to contacts is optional and only used to save new senders to the address book. Continue turns active once every required permission is granted. If you denied a permission for good, the app takes you straight to the phone's settings.
3. Pair the phone with your account
In the dashboard, open SMS Gateway › Devices › Add device. A QR code and an 8-character code appear on screen.
- Scan QR: fit the code inside the frame; pairing starts by itself.
- Enter the code: type the code, shaped
XXXX-XXXX, then tap Pair the device.
The code expires after 10 minutes and works once. If it has expired, generate another one in the dashboard.
4. Choose the SIM card and the limits
The last step sets up the device:
- name — the phone's model by default; you will see it in the list of devices;
- SIM card — on a dual SIM phone you choose the card messages leave from;
- daily limit — how many SMS the phone may send in a day (500 by default);
- pause between SMS — how many seconds it waits between two messages (3 by default).
Carriers may block a card that sends too many messages in a short time, so match the limit to your plan. You can change both at any time from Settings.
5. Check it and send a test SMS
After Finish enrolment, the app shows a summary: the name, the card, the limit and the device ID. Tap Send a test SMS to check the route end to end, then Go to the dashboard.
From here the gateway runs in the background, with a permanent notification. What comes next — statuses, reports and what to do when the connection drops — is in SMS Gateway: how it works and what to do when it stops.
