Ive successfully installed playsms 1.4.3 on Ubuntu 18.04, Ive installed on a physical machine at the moment for testing, I also have a Huawei 4G USB Dongle, do I need to install other plugins such as Kannel to send SMS and bulk SMS to real mobile/cell numbers.
Not sure on how to add the dongle to playsms and assign to dev for sending.
If you want to use your own sms usb-dongle/hardware/terminal you need to install and configure eg kannel, gammu. Both are integrated with playsms with plugins (SMSC/Gateway configuration). There’s multiple howto’s available eg: https://playsms.org/2021/01/26/testing-playsms-with-kannel/
I ended up with gammu because it was the only one i could manage to both send and receive danish chars: æøåÆØÅ
