I do type a message and save it in the drafts folder whenever some idea hits my mind. The drafts folder can store up to 20 messages and the memory is filled now.
So, I type a message and send it at my own number and I receive a message in some seconds. I followed the routine and now my inbox memory is also low. So, I have to delete previous messages in order to receive the upcoming messages.
I hate this practice as I may lose some important messaging about to arrive at my inbox.
I think I should change my mobile phone.
