Physical Sim user here. The great thing about Sim cards is that you can easily move them from one device to another (for most carriers) without having to contact customer support. Going on a rough trip (say, boating)? Move your Sim into a beater phone that you don't care if it gets destroyed or drowned. Esim makes that use case more difficult, as you would have to contact customer service twice for that case.

Great video, explained it well! Now I just have to decide to go with an eSIM or traditional one for my new phone that arrives next week.

Thanks Gary, this is an excellent in-depth explanation of what eSIM is.

May be you could do a video on the security of eSIM and whether SIM swapping can occur on these.

Thanks, I've been wanting to see somebody explain e-SIMs. Glad it's Gary. ♥

I'm looking at getting a new device. Saw a phone which offers dual sims namely SIM and eSIM . Thanks for your summary.

Dear Gary: I'm interested on a demonstrative explanation of WiFi Calling. Thanks for your efforts.

Was unaware of this until now.

updated to a newer iPhone (forget version) and have not activated due to not working when following instructions from my carrier. This seems to be some artifact of the Sprint merger and hitting some edge case. So currently I am a regular SIM user on an iPhone 11 waiting to use my newer eSim-enabled iPhone still it its box. I will take it in to a Sprint branch at some point to get the better camera of the newer phone.

More space, they should reborn the 3.5 jack port

I have a Pixel 6 Pro with a physical SIM, but I'm inclined to try a second pre pay eSIM. A least I know what is involved now. Thanks Gary.

eSIM is good until I broke my phone. It was not easy to recover it as you would need a spare phone with eSIM to transfer it while waiting for your original phone to get repaired. While it was only my secondary number but the pain of not having a physical SIM to just pop into another phone really makes me rethink the pros and cons of eSIM. Luckily I got my original phone replaced immediately when sent for repair hence the downtime ended up being shorter than expected. :)

My s10e is the traditional sim card. I just upgraded to the G S23 Ultra. I'm just getting hip to eSIM. At the moment I'm having a hard time trying to remove my sim card❓🤔. So I hope I don't have to add the sim card from my s10e to my Gs23 Ultra..

Thanks for the update on eSIMs. I guess I could have used this concept on my last trip to Europe. I have an iPHone Pro Max.

In my opinion, the esim is the way the network will further control and limit user experience. Only phones they see as acceptable to the network will be allowed to function on the network. For example, phones that are imported to here in the US don't utilize the esim so they would be out and networks could further limit things to only devices that they sell. This limits your choices as to which phones you use.

Is it really new technology or just integration into VLSI of the chip ?

One advantage I see about the e-sim, is that it won't get damaged from miss handling it, dropping it, greasy fingers, etc.

All makes sense however you talk about eSIM like its a choice over the old SIM however state it is built in. You also say it frees up space for other components however lots of new phones came with a nano sim spot and built in eSIM. Also, and most importantly, Can a small eSIM chip be purchased to make older phones compatible with eSIM?

I have the pixel 6 pro with E-sim capability. But I was wondering if I say use a physical SIM and an E-sim ( activated). I was wondering if I could add More carriers to the e-sim and essentially have a triple SIM and use/activate each one depending on the needs? so not necessarily simultaneous use of all 3.

Thanks professor. Great explanation

I don't think eSims caught up much in my country so far, though I think they must be a thing for iPhone users... vast majority of people won't be on latest flagship devices though, it's mostly older mid range to low end down here, so most of them won't be compatible with eSims. Heck, I don't think most people even jumped towards USB-C just yet... I still see a lot of people carrying smartphones with microUSB ports. :P There is just one thing I don't like much about eSims, and that's uniqueness and portability. I think this is different to some other countries, maybe someone else will be able to explain and compare this better than myself. But at least afaik, here where I live a Sim card is unique. You cannot have 2 Sim cards with the same number, so it's kind of a deterrent for cloning and whatnot. I have also moved my SIM card from one device to another for different use cases... eg. from smartphone to tablet to smartwatch. It's a hassle, and rare case, but just temporary measure. The thing is, once this all becomes software based, the security and rules of using it are dictated by carriers, and this is the real problem for me. For instance, will the carrier allow me to use more than one device with the sim? What limits will they impose between IMEI and IMSI? What I really wanted is to have a single number for 3 different devices simultaneously... the smartphone, a local phone that is there for backup and to replace the landline, and a smartwatch that I wear while out and about, particularly when running and I don't want to take anything else with me. But I imagine carriers won't allow me to do this, because they'd rather force you to pay for extra accounts to have that sort of functionality. I also wonder how much of a different this would make for security and privacy. Not that having a physical chip with info is that different from the info being embedded into the device's own hardware, but a degree of separation is there. In any case, with iSims being a thing, I guess it's just the way things are gonna go.

Why did you stop speed test g?

Can DSDA be extended virtually a la eSim+SIM simultaneous operation? Sounds easier than DSDA firmware mods

Just a correction, I saw list mentions compatible Samsung devices with an exception of S22+, however I beg to differ,I am using S22+ and have used an esim on it acouple of times. To be more precise I'm using the exynos variant.

eSIM further limits the consumers' freedoms. It's just one more thing the software on the phone can lock you into.

Just a thought. There are over 30 million used phones sold every year, so with an Esim how does that work when the Esim is locked to the original purchaser?

Summer phones have both esim and normal sim also.

I have to use an esim for my 2nd line (iPhone 14 has only 1 physical sim). Problem is all the cheap plans are physical sim only.

Yes, I have a Galaxy S22 Ultra, and am using an eSIM and a physical SIM when I go overseas. So I can use both when necessary.

Thanks for the explanation. In theory, with an eSIM, it should be possible to use the same SIM across multiple devices so you can have a single phone number that can be used across multiple devices for phone calls and messages, right? Like how it can be shared between an Apple watch and an iPhone (subject to carrier support). So why isn't it advertised as such? Any security concerns there? Would love it if Gary explains this as well :)

While I was activating esim, error in reserve profile error code 1, how to resolve 😢😢

Hello my name is Gary eSIMs and this is Gary Explains

eSIM more battery saver since smaller and embedded on SOC?

Is the QR code provided only valid until Esim activivated? Just thinking of criminals that might make a copy of the QR code and trying to activate it on other devices as well.

Im still kinda new to esims, can they be used for prepaid services? Or is it exclusive to postpaid?

I got got an eSim few days ago and I absolutely hate it. You are restricted to one device and you can't swap it more than 2 or 3 time a year. This is totally against privacy.

How many e sims can I use on an iPhone

IMEI isn't connected to the device but to the sim card slots. If you have 2 slots, you have 2 IMEI numbers

Gary they're called iPhone 10s and 10r not Xs. I'm surprised you of all people made that mistake

I tried getting an esim from o2 and that didn't work well. They sent 3 different bar codes for the esim and on 3 occasions none of the bar codes worked. So not a good experience.

i have the S22+ and it has esim.

Can we get Gary eSimms?

esim explanation starts @3:14

It was a funny situation when my friend bought a phone, pulled SIM slot out and prepared to insert a SIM card there, but... he searched and searched for a card in the phone box, but no card at all. He found just some paper with a number. It's your new SIM card, I told him. Are you kidding? No, I didn't. He called CS, told the number and made the phone working.

There are will be pros and cons. One in case of phone is destroy it need replace. Or transfer to new phone.

Now, they're coming out with iSIM which moves the SIM into the processor itself.

How’s e sims with locked iPhone 12

Gary, would you explain how an eSIM digially moves between phones (from an old or lost phone to a new phone) please?

Let's exchange a hardware key for a QR code, what can go wrong? Especially now that confirmation codes for bank transactions and alike are sent via SMS. I see absolutely zero benefits for the customer, just a loss of control. If my provider ever forces me to use eSIM I'm switching providers.

Is there a difference between eSIM and iSIM?

I just bought the Samsung Galaxy a54, and it has the e-sim.

I don't really like the idea of an eSim, I always carry a spare sim to pop into my phone, should I need a change whenever I wish. 😉

Now we have iSIM

I have an eSim on my Galaxy watch now it is fine. I had trouble finding a TelCo company that used eSIM that was over a year ago. I live in Thailand.

if you have iphone, esim is good in case you lost your phone, since no simcard can be removed, so your phone can always be tracked....

The Pixel 2 had an esim.

Interesting I am in the USA using Verizon and I don’t see any IMSI only a ICCID or a EID or a CSN number except of the IMEI I thought the IMSI is used for the global travel sims that have multiple carriers so every carrier have its own IMSI even you only have one ICCID

Sounds like a hackers/cloners dream.

I think Apple chose esim because of the high volume of stolen phones from stores and shipments. Not so much on customers! You rarely see where there is a rush on stolen Android phones! I will continue to purchase sim vs only esim! Thanks Professor 🎓

I thought e stood for electronic for some reason 😂

MACs can be changed or faked, same for IMEI...

I use dual physical sim. More secure.

eSim can potentially be an anti theft system as the sim is not removable.

I use two sims, a physical sim for work and personal esim on iPhone 13. The reason for not having two esims is that on carrier demand that I need to visit them when i need change my phone, which is not cool.

I have S23 ultra, it can't use 2 active eSIM, only one active at a time> "The Galaxy S23 Series offers a Dual SIM slot and also has eSIM support. User may use up to two physical SIMs or 1 eSIM & 1 physical SIM at the same time. The Galaxy S23 Series lets you store multiple eSIM profiles, but only one can be used at a time">

came for help, got a PowerPoint

What happens when you change or buy a new phone, you lose all your contacts?

eSIMs are a bit of a nightmare with a broken phone. Bitter experience, so never again.

Hey, this video is two hours old! I thought you claim to cover new technology! What is the history channel??

I do not like this. I would prefer my SIM to be device independent. There are all sorts of downsides to this. For instance what happens if I go abroad and temporarily want a local sim card? Having it tied to the device will create a lot of bother.

eSIMs are yet another nightmare for privacy. Since you can't remove them from the phone and phones with removable batteries are a thing of the past, the only way you can be sure you're not being tracked is to leave the phone at home

Bad review, sound like a marketing material, without mentioning the bad part of eSIM. Which is when transferring the number to new phone is *NOT AS EASY AS* using the old SIM.

I heard that Esims are burdens on battery( they suck battery more then the normal Sim, some has reported that it takes like 5-7% of battery) , so is it true ?

eSIM will be something of the past in a few years. iSIM will replace it, which will save even more space and increase security

We were warned about these esim cards. Now carriers can limit your access to whatever they choose and worse it can be used for tracking purposes. They'll say that it's in case you lose your device etc but it's more about tracking you, especially through the ever-controversial 5G. No, I'm not one of those conspiracy theorists but I can read and understand what I read, especially in the small print that everybody ignores. Another interesting point is ... who remembers back in the day when we could only use our devices on certain networks or with certain providers? There's a good chance that's coming back. Just watch.

Huh?

Bonus is that as the sim cannot be taken out, you do not need a sim pin. You can just disable it.

Gar e sims

He didn't explain why Apple want to push eSims but the networks don't want them.

Yea naw they are easier to hack 🤣😅

I'm a regular person. I bought a regular budget smart phone. It works great. I have looked after it and so it still works great. It will still probably work great in 5 years time if I continue to look after it. But will the world have 'moved on' such that it no longer works great? Probably. Technological progress does not benefit everybody.

I'm concerned about privacy since I'm not Hunter Biden and don't have the FBI on my side to cover my a$$. Will multiple esims get leaked to the carrier? When traveling to certain countries/satellites (China, Hong Kong, Macao, etc) I worry about privacy as the minute I go through the airport I'm being tracked facially...
