If they want widespread use, as many countries will not adopt one, there should be a system that allows reading a plain SIM card then make it appear it is installed in a phone.
that card reader will brought when a person travels to a country which doesn't support eSIM system.
This is why I think eSIMs were conceived:
Do you think the eSIM will allow two phone numbers to be active at the same time? Like dual SIM phones do...

There still will be dual sim phones so there will be dual standby and dual active phones
TWO cell phone numbers
Then there will be the traditional single sim phone, so you go on holiday and to avoid roaming charges you use a local sim card
Same thing instead of switching sim cards, the easiest way is to log onto holidays network and ad long as your phone us not lost or stolen (eg Clean IMEI) your phone can accept the new holiday number you top up electronically
You real number is temporarily deactivated just like removing a physical sim
Why is this good for GSM
In the USA the other technology is CDMA phones which don't use sim card, Verizon Sprint.
You activate the phone so providing it is not lost or stolen you can switch networks
Because there is no physical card, it affords a very high level of security
If a phone is stolen all a thief has to do is swap sim cards, with an esim they cant
The other thing is location relies the phone being BOTH on and connected to the network
If a thief can change the sim card as it can't be re registered it has to be turned off in order not to be located
Say your phone is stolen from home whilst you were on holiday, all the Police have to do us see who has re registered the phone and what numbers were called, but it may be unlikely that will be necessary security would require actual ID
Apple and Microsoft have reset Protection this stops the phone being used for call, location if the lost phone is made easier if they can't just change sim cards
A stolen phone is no good if it has to be switched off
FINALLY there is no reason why esims can't be worldwide
For ultra convenience to users, should simply allow basic ID plus pw logging in the network. much like logging in the email service, online bank account. with this way, changing phone everyday would be a fun. depends on the need, the activities in the hour. esim is a step toward this direction, but not the same thing yet. with esim, the need for multi sim tray can be dropped.
But, for security concern, a physical device is needed. the sim, is an device allows the network operator easier identify a user, less tricking can be done. the sim card is the most basic ID, on top of this, many other online activities are done.
Phones with eSIM is good only if it can enable more than 2 cellular phone numbers of different carriers or network providers to be used simultaneously, like Dual SIM functionality. It should also include a few handy options like backing up data to migrate to another phone with an eSIM built in and an option to clear all the data by yourself or remotely in case you want to sell your phone or in case, it's lost or stolen. This requires an universal approach from the manufacturers and carriers/network providers/telecom industry for the technology to take off. Otherwise, it's just useless in my opinion. Phones aren't getting any slimmer anyway, we aren't seeing 1 mm slim phones even after the removal of 3.5mm Jack.
Microsoft was also working on esim as a way to have connected PCs or connected devices(all running windows core). If Surface Phone gets released it would come with esim. Still waiting...
Anonymous, 15 Oct 2017Â„given the time it will take manufacturers to include eSIM's as standardÂ“ See USB CFrom like may 2012 it was micro USB. And as european union said all charging cables should be unified but they wont. Apple still have own because apple thinks he is something special. Now we have USB-C wich will be unified for all devices until something really cool and new arises. But apple will still have own no matter the rest of the world use USB-C.
Its same with the E-Sim.
Its a great idea but when you loose your unified number or get stolen someone will gain acces to your phone your contacts and probbaly will revrite it to make it your own.
They you get a bill big enough to buy a house and someone will be very happy for a good joke and the other person will have eyes for tears.
No matter how good this will be or it sounds there will always be one certain word wjhich gives a lot of questions. (BUT)
Great article!!, very excited to see what this new technology has to offer especially with 'The Internet of Things'.
Â„given the time it will take manufacturers to include eSIM's as standardÂ“ See USB C
And sooner or later skynet will rule the world, the mark of the beast is coming to a close.
If I have 2 phones I usually switch back and forth, will it still work würg eSIM?
I don't get why they didn't use nano from the first day, i mean considering you can cut your mini simcard to fit and work just fine :|
still I wish we didn't need a simcard. we could just use the internet for calls!
Lol the chip was always same size only thing was the size of plastic,even in nanosim you can see the chip inside...
this is exactly what i always think about. eSIM should be on motherboard and carrier operators just code the telephone numbers into the esim, so a phone can carry about 20 telephone numbers or lines you don't need to carry two phones for two simcards, just inbuilt simcard will handle as many as 20 telephone numbers from different carriers.....My dream is coming real
Wow! It was a very pleasing article.
Thanks to GSMArena and thanks to the guys who contributed anyway in this technological progression.
