Hi all, question: If I send an iMessage and it says "Delivered", is there any chance that it doesn't reach the person's iPhone, iPad or Mac? Say there is an issue with their SIM card on their phone and or their apple ID or whatever, if it says "delivered", does that mean it did reach one device, thusly can be read or is there a possibility it says "delivered" yet the person cannot read the iMessage on whatever device they usually use (phone, mac, ipad.. one of those, whatever)?
