Well, is texting more or less like email, in that you can delete them (and in fact should if you don’t want to clog your system)? And it was 4:30 a.m. Does texting wake you up from a sound sleep, unlike email?
Receiving a text can trigger a notification sound on your phone, if you have the sound turned on. Also, you have to have the phone on. If you turn the phone off, you will receive all the texts that came in overnight once you turn the phone on in the morning.
