I have a lumia 822 and I'm getting sms delivery confirmations for only some numbers. I did a soft restart and a system restore and checked all my settings and nothing changed. I know some messages are being received because they respond back but with no confirmation that it was received. other messages I am getting nothing at all. So I don't know if they are going through or not.
Help is just a posting away! I'm confident that together we can get your sms delivery notification working properly and consistently. Let's start with are you using the stock sms app on the device? Also, what software version do you have on thce Lumia 822? Can I assume that there isn't any physical or liquid damage on the device? As you share the details then we can investigate.
