Need the Mint Mobile app on the phone (and an account at Mint mobile) , but after that the "SIM data" is provisioned electronically to the phone. But mint says there is a matter of minutes (presumably as long as can put the phone on WiFi to get a data transmission).
Carriers have to deploy the correct provisioning infrastructure ( can't guarantee they will do that right. Especially if they are dealing with subcontractors/etc. who sale/resale plans on commission. ) The part the carriers have to get over is how to authenticate the person and deal with the phone API to deposit the provisioned "SIM data " into the phone. Transmitting the data securely shouldn't be a problem if have the right "back end" equipment installed.
There are also users out there who have put in a SIM card upside-down and it doesn't work. That didn't stop sim cards from rolling out. There is almost nothing that completely bungle free by an end user proof.
Can't move until all customer service agents are not clueless. That is just doom. Always going to be storied about customer service folks who messed something up.
It is the step at the start of the process of how do you get the "eSIM data" to the correct phone/user that has to be secured. There is no generic app to do that. Apple could fix that by providing some "hand holding" and guidance of which app and which steps for a provider. It is a "smart phone" is should be able to do something 'smart'.
