Hi, I am building an app that would automate sending SMS to the staffs of a company this festival season.
I read that android enforces a limit to the amount of SMS you can send in 30 minutes ( 30 SMS ) but I can't seem to figure out if its per number or total SMS sent by an app.
Hmmm I took a look at it now, it's funny because I actual have a sample running just ok, I don't know but it's run ok on android 8.1 beside I read @Erel posted it's only relevant to Google play store apps, this app is a private app and won't be available on play store
You should not send more than 60 SMS within one Hour. Android may prevent it.
There may be a limit given by your Provider.
By default, Android limits apps to only sending 30 SMS messages per 30 minutes (on newer versions of Android starting with 4.1 Jelly Bean), or 100 SMS messages per hour (on older versions of Android).
I would use an external SMS Provider to send out all the Invite SMSses...
