I need a device that can make telephone calls, consistently 24 hours a day. To be able to maintain 2 calls at 1 time like basic mobiles do. And also need it to call various numbers that I provide randomly throughout the day for under 20mins per call.
Would like it to be battery operated (rechargeable) if possible aswell as mains charger
I will have a sim card to place in the device, which will allow it to call.
