why the hell do you need a plastic chip? its useless and redundant.
get a username and password from the phone carrier and that's it.
just like connecting to an ISP for example.
why are people clinging to old technology for no reason.
Besides, phone carrier nowadays are exactly this: ISPs. they provide an IP and a bandwidth.
maybe if people stop clinging to old techonology and use it the companies will be forced to advance as well.
maybe stop using fax machines and they will stop producing them!
There are several companies that provide travel esims. I use knowroaming. Much more convenient than trying to find a shop that sells sim cards after you arrive.
Because I'm much more likely to lose/forget a username and password and going through the hassle of getting a hold of the carrier, proving who I am, and recovering said info is a bitch. I'd prefer to not go through that over and over. I buy my phone out right with no part of the carrier. They have no need to be a part of me switching phones.
