In my new dorm, the cell service is shit. As a result, it is not uncommon for me to lose 40-50 percent of my battery overnight just from searching for service (all radios turned off). So my question is, if i turn my phone off at night so the battery doesn't drain, or put it into airplane mode, will I receive any and all messages that were sent to me when I turn my phone back on/turn airplane mode back off?
