A
Android Central Question
There are many app which provide the capacity to send grouped SMS. However, much of them are not using the GSM protocol but the internet protocol.
I am looking for a solution which is using only the GSM/SMS protocol in order to be able to communicate even in case 2/3/4/5G is not available.
Is there an Android app to do so? or another way through a PC with a cable (no internet is my constraint).
Thank you !
