USB / Integrated SMS Modem
DataTalk allows you to use your own LTE USB modem, so you can keep your device away from the internet connection and still receive notifications from your technology. To set up the Modem, please follow the video.
You need to supply DataTalk manager modem settings with the AT COM PORT, which can be found under Device Manager in Windows
Currently supported USB modem – TELTONIKA TRM250
However, any modern modem with standard AT commands may work; we do not guarantee this.
The {phone} placeholder in the notification set-up will get automatically replaced by a selected user’s phone number.
NOTE: For Linux users, if you’re having trouble with the SMS not being sent out, please check whether some other app (like modem manager, which is installed by default in the graphical Ubuntu) doesn’t use the modem’s port, blocking DataTalk from using it.
To start with What’s App notifications, you must have a Meta Business account and follow the META business setup.
At the end of the process, you will reach the WhatsApp API setup, giving you a test phone number for testing purposes.
It will also generate a unique Access token, which you will use in the notification tab
Which you will then use to replace the URL for notification:
whatsapp://{token}@{from_phone_id}/{targets}
Keep in mind that WhatsApp notifications are paid according to the META pricing

Discord
Discord allows you to send notifications directly to the channel. Nothing special is required to proceed with Discord notifications, as shown in the video. You only have to create a webhook in the channel and copy the webhook URL, just as shown in the video. Discord notifications are free.
Telegram
Telegram notifications are also free; all you need to do is create a bot using @BotFather, which will tell you how to proceed with the bot creation and give you a special bot token. Which you will use as the template
tgram://bot_token/chat_id
And chat ID, which can be found by using this tutorial
Then you have all you need to create a testing notification

It is capable of sending simple E-mail notifications to your SMTP server for free.
All you need is to know the settings of your SMTP server and fill them out into the template.
mailtos://{smtp_server}:{port}?user={user_email}&pass={password}&smtp={smtp_server}&from={user_email}&to={recipient_email}&mode=ssl
This is an example template that you can fill in with your SMTP server/address details.

SMS
Allows you to send SMS through the SMS gateway, which is mainly paid / per SMS according to your provider.
- SMS Manager (Czechia Distributor) – can be paid in CZK
- Twilio
- Any other provider
This is an example of a notification from Twilio which provides a free trial to try out the notification.
twilio://{account_sid}:{auth_token}@{from_phone_number}/{to_phone_number}
