There is one contact in my phone that if I send an iMessage to him first, it will not deliver, ever. He tells me he hasn’t hear from me in weeks, even though I text all the time. If he texts me first, and I answer relatively quickly, it will deliver and he gets it, but if I take an hour to respond, it never delivers. The same thing happens if I call, sometimes it will work, other times, it rings once then it goes straight to voicemail. He never gets a “missed call” notification. What’s going on?
