How can you tell when someone receives your text messages? My friend responds to texts after a long time, sometimes a few hours and they always give an excuse that they just received it and replied immediately. How can I tell the exact moment they receive my text?
Go to message settings and turn on receive delivery reports. The procedure varies from phone to phone but the general settings for Android (which am using) is Messaging > Settings > then ensure Delivery reports is selected.
Now every time they open your texts you get notified via a delivery message to your inbox.
