How to turn on SMS over IMS?
SMS and IMS are some of the features that many people use, but few are taking care of. Even so, in the world of developers, it is just an ordinary feature.
The meaning of SMS is Short Message Service while the IMS’s meaning is IP Multimedia Subsystem.
If you are going to toggle between the two modes, it will make the text messages and calls put through VoLTE which means Voice over LTE.
Because of the subjection to vote, the messages are mailed in two ways.
The first one is by way of 4G/WIFI connection text messaging, then the other one is through 3G?2G.
In short, the messages and calls that are being sent depend on the Internet Service Provider.
After the SMS is turned on over IMS, messages are sent over the 4G connection network instead of the traditional 3G and 2G.
In a lot of places, the options do not work, and even you change the options to each of them, there is no result seen.

SMS on top of IP was fully identified 3GPP Rel 7. It’s up to the IMS and it is deliberated to provide affinity between the existing cellular legacy and the implementations with more detailed messaging capabilities over SMS and IMS networking.
For some without IMS, a transition solution was named. It is previously called with misleading name SMS over CS but this is called SMS over SGs.
It allows the transmission of native SMS from CS infrastructure over the LTE radio network which is a hybrid approach.
SMS via SGs was identified as part of Rel 8. SMS service for mobiles in LTE is provided by SMS over SGs and it is intended to be a transition solution because it requires a CS domain infrastructure for the SMS transmission.
What is turn on IMS registration required?
IP Multimedia Subsystem or IMS is a set of designations to give numerous services such as data via IP protocol i.e. the internet, multimedia, and voice.
