Explained: eSIM and SIM Card

[@lyenhua]

Ok folks go straight to 3.00 for eSIM. You are welcome

[@charlesmcgehee3227]

That one sentence explaining what an eSIM is was all you needed to say. Thank you for your time and the information I needed!

[@ZackCase]

Anyone else distracted by that awesome poster?

[@pilotmedic]

Back when the esim started coming out the companies always told me that I need it to have both numbers from the same carrier. Nov 4, 2021 I just bought the OnePlus 8T cell phone Wich is CDMA/ GSM, I have a Verizon sim and T- Mobile sim in the same phone. Works great.

[@redstrass2257]

Lol. The Simcard technology didn't get smaller, phone manufacturers just decided to remove the extra plastic (which made it "smaller and smaller") thus the micro and nanosims (which are essentially the same, just with a smaller plastic footprint)

[@angelluistorresjr8358]

Another issue is someone like myself like to have two cell phones and I like having unlocked phones directly from the manufacturer.

[@toadsdude992]

But with e sim, when someone stole your phone, they cant use it until they go to the step to change the number. Therefor its more chance for us to recover our lose phone

[@adityabagul3657]

If you complain to cops the sim will deactivate buddy

[@shlomiunger3518]

It also means the government will be able to track you ALWAYS... You'd have to take out the battery and render your phone useless instead.

[@toadsdude992]

@@shlomiunger3518 well, i don't mind if government track me. I need to track my phone in case somebody stole it. And i don't think government have an interest in my data

0:59 The SIM doesn't "receive" or inject the "signal" into your phone! that would be the Rado-Modem CHIP, The SIM is just a low-capacity memory that contains the data needed to connect to your carrier and identify you as a user, in the past, you can also store texts and contacts. Is a carry-over technology from the first era of cellphones is not really needed nowadays.

[@glynpowell5275]

Please explore the way this system can be a dual SIM system with the two numbers present all the time.

[@LilMomo29]

I have to fast forward to search for that 1 sentence :3 but thanks for the video

[@CompadreLucho]

Volvimos al principio de los tiempos.

[@norehanyahya2284]

SIM card or eSIM main role is to facilitate authentication by network that you subscribe to. That’s all. It can also store apps, contacts and so on but nothing major...

[@muhammadshahab2730]

just simply define the difference between esim and sim

[@Bilgewater]

Great explanation!

[@machukis1]

Awesome detail in your explanation! Thank you….

[@paopaowell]

now i just realize that is subscribe identity module LOL

[@Batman-ht9ym]

Wait, how do you make call to switch plan? Let's say, if you have a US plan and you go to UK, and you want to switch to UK plan, you are calling a UK number using US plan, and that would be expensive. Wouldn't it be nice that you can just get a sim card at the airport and swap without hassle like needing to call someone?

[@maninthecab]

Jack Yu That’s exactly what I do - I’m in the UK and my normal account is on the esim , when I go on holiday I simply buy a cheap pay-as-you-go SIM card at Bangkok airport , and , Bingo ! , I can make local calls at local rates and still receive calls from home , all on one phone (or choose to turn off the UK number to avoid costly incoming calls ) .

[@casandrajudge5624]

This was super helpful. Thank you!

[@hopper1629]

When he finally gets to the only thing I wanted to know he says "for all we know it MIGHT have the ability to have dual cell phone numbers" 🙄

[@oxBadiaxo]

I currently work at T-Mobile and I'm finding out that my customers having a hard time switching like to know more info. But how can a provider like myself learn more about SIM cards and how they work. Ive tried researching this since my last job with a different provider.. what i want to know is the difference between international and domestic sim cards and what all the acryonyms mean

[@meyou9651]

I learned alot....thank you....I too, dont want to call to speak with someone from my company to get my info switched over from old to new phone AND I sure Dont want to talk to the company when traveling abroad to get a new number then call back, before i leave to have my old number reinstated..... just give me a good old SIM card. Sounds like a👎 for an eSIM.

[@rayleeaustralia]

The point is that you don't save any space, the dual sim feature will have a slot for one SIM card n the other for esim

[@maninthecab]

Raymond Lee Err , no , there is no slot for the esim ; it’s simply a module in the installed firmware.

[@angelluistorresjr8358]

Honestly it doesn't make sense there was a time before a SIM cards when it was embedded into the phone already so in a big way I feel we're going backwards

[@ShapeCZ]

SIM cards don’t “inject” any signal to the cell phone... lol

[@diehardAMD]

I bet if I look it up.... I bet you're wrong. I bet it matches the hard programmed IMEI number (located in the phone's hardware) to the carrier's provided number that provides an account for encoding over the CDMA-type or GSM-type carrier waves for subscriber identification. It acts as a "middle man" like he said between the device and owner to the carrier and tower.

[@ShapeCZ]

Chris Look it up 😉

[@borntodoit8744]

[@sleekbook]

How about eSim vs CDMA ? CDMA phone dont have sim card too.

[@Babblingboolean]

It's a similar concept. It seems as though the cellphone industry likes the idea of CDMA (the technology being built in the phone) but over a GSMA signal.

[@SoyAlexDeMex]

CDMA phones do have sim cards

[@PearCoin124]

i like physical sims over esims

[@giladwasheretravel3553]

Why does this video have 30% thumb down?? It was great. Thanks dude

[@angelluistorresjr8358]

It probably got so many thumbs down because he didn't really get straight to the point it was kind of dragged out

[@Babblingboolean]

No clue. Made the video simplified for everyone. I guess people dislike esim so they disliked the video? Lol who knows.

[@brianfong5711]

I think you need some sound absorbing panels. A lot of sound bouncing happening.

[@Babblingboolean]

Yeah, I got similar feedback from other viewers. I upgraded my audio setup and it's much better throughout some of my latest videos.

[@brianfong5711]

@@Babblingboolean Thanks for the upgrade!

[@mcunhabr]

eSIIM sux. It's a huge step back. It's just like old analogical phones, were you need to contact the operator to activate the service.... Is too much sacrifice to gain a little space. Much worse than remove headphones jack.

[@peternielsen7855]

Dropping the physical slot would indeed suck. However, offering eSIM + nanoSIM like the iPhone XS does is the way to go. Prevents disaster like losing the SIM tray in-flight while swapping SIMs. Now we finally can have two operators and switch in the phone settings instead of playing with fire...

[@Bryan_Lai]

Is it possible for the carriers to develop the apps which allow users to inject their numbers through these apps?

[@josezonio4820]

looks too greedy for them to do so even phone plan customization is not an option for them for cheap and fair value for your dollar. just look at usmobile where u can customize plan which is the only carrier who offer s it in us and globe telecommunication in Ph.

[@ShadiFagihi]

eSim seems like inslave customers to that one specific carrier.

[@kwocci3049]

@R J l think that they meant to say enslave.

[@MJComics309]

Pretty great idea

[@geoffreythorberg2580]

eSIM is a step backwards. My first mobile phone in the 1980s... it was embedded in the unit... could not change it as easily as a physical SIM... eSIM is NOT easy - right... NO NO NO it is a hassle and takes longer than the three seconds it takes me to swap a physical sim.

Thank you for the heads up mate...!

[@HaseebHeaven]

Stop explaining sim card too much and more explain eSIM

[@rolandwelz]

Not at all accurate. When properly implemented you can swap, add, switch, and store multiple carriers with ease. An e Sim is programmable so you can just add a new carrier by adding a new sim code although right now not all carriers are setup that way. An eSIM may be provisioned remotely, but end-users can add or remove operators without the need to physically swap a SIM from the device, just add a new SIM code. No phone calls needed.
