Message delivery report in Oppo smartphone

Despite the fact that SMS text messages have somewhat lost their relevance recently, many still use them. For example, for transferring meter readings for water, gas, electricity, etc. And in this regard, it is very important that the message exactly reaches the addressee. But how to find out, do not call your mobile operator every time?
On your Oppo smartphone, you can enable the SMS delivery report, which is usually disabled by default.
