Hi Ashish
Firstly, please try to avoid using the term "service" as far as possible when discussing commerce and product ordering. The word "service" should be confined to its formal meaning in the OSS/network domain.
In your example, you would start with the product catalog, and create specifications for the underlying things you are offering, such as data, voice, etc. You then create product offerings that use the specifications, and add the commercial aspects such as prices, terms, qualifications.
As part of a shopping cart or ordering process, you would instantiate Products from your offerings and specifications, and at some point during the ordering process you would persist these in the product inventory.
You can see examples of catalog models and orders in the ODA use cases IG1228, for example use cases 3 and 4 for fiber broadband, and I think use case 8 for 4G/5G mobile.
Good luck
Apologies for the delay in reply, hope it's still helpful.
