I believe eSIM will be a significant change agent for the Mobile industry. I’ve posted many eSIMs updates. I evaluated eSIMs for a client during 2018.

Least Cost Routing is harder than it looks
All voice network operators are continually looking for ways to cut the cost of delivering outgoing long distance calls. The best way to do this is to use 2 or more Inter-Exchange Carriers (IEC, in FCC-speak) or what you and I might call “long distance service providers,” and cherry pick the cheaper provider for each …

Traffic Pumpers Filling Long Distance Pipes
Starting late last year our long-distance network has been overwhelmed with calls to various for-free services. These services often appear to be the proverbial free lunch, with no apparent business model because the service is 100% free to the end user. Typical offerings include free conference calls or voice chat rooms. These services can completely …
