Android app to Bulk SMS from csv lists with Schedule

[chribonn]

Hi,

I am involved with a number groups. We periodically communicate to members using SMS.

Is there an android app that:

* Allows me to have separate phone lists in csv or text files
* allows me to schedule SMS messages.

Each list consists of under 100 numbers.

I want to avoid at all costs having these numbers included as part of my own contacts.

I am interested in both paid and free solutions. I would like to use the SMSs that are part of my phone bundle.

Thanks
