Hello, Quaddurup. Oh, ITSub, nice to meet you. Hi, Sunho. Nice to meet you. You guys look still terrible after a while. You a 10GB... Hello, this is ITSub. It has been so long that I've been using KT. I was actually satisfied using KT, and when I started YouTube literally from scratch, they kept renting me new devices without any conditions, and I had an image of the company as the one who helped me when I needed help, so, I always stuck to KT. So, I'm currently using my mobile and the Internet for my house and studio with KT, the amount I pay to KT for a month is about ₩300,000. KT hasn't been offering me adverts for years now, but since it's one of my favorite companies, even though SK or LG U+ offered me many more adverts, there was no advantage for me to change my broadband abandoning all the services out of a sudden, and I couldn't do a promotion for a company that I don't actually use. But now after a few years, I'm going to explain why I got to film a don't-recommend the 10Gbps Internet. [1. The reason I use 10Gbps]
First, why I use a 10Gbps Internet, I stuck to 10Gbps since I was satisfied with it, but for usual users, 10Gbps is not really necessary. That's because 1Gbps is enough. But for the creators like me, or in the offices where they upload and download a lot and deal with heavy files, it's 10Gbps that has many more advantages than 1Gbps. If we talk about 10Gbps since it's 10 times faster than 1Gbps Internet, you might say the speed is the most beneficial bit of it, but for me as one of the actual users, the bandwidth is the biggest advantage of all. For example, with the 1Gbps Internet, if you download and upload in 4 PCs at the same time, they have to share the speed within 1Gbps, but for 10Gbps, you share the amount of 10, it is an advantage that you can work more comfortably. The disadvantage is the high monthly fee, and the price for the devices to use 10Gbps, is a lot. [2. My case of experience]
Right, then talking about my case of experience, might be a usage review. After I've moved my studio to Yeonnam, I immediately installed the KT Internet for the convenience of my employees. The price is ₩88,000 every month for a 3-year contract, which means I've spent more than ₩1,000,000 only on the Internet a year. Compared to the other plans, it's 4 times more expensive than the cheapest plan, and it's twice as expensive as the 1Gbps plan. Of course, I wouldn't feel it was such a waste if I got to use the service properly. However, a few days ago, I found out that the Internet in our studio is being supported with 100Mbps, not 10Gbps by chance. At first, I thought there would be something wrong, and tested out many different kinds of stuff, turning on and off the MODEM, disconnecting the router, and connecting it directly to the devices. We've tried so many different ways, there was a limit to 100Mbps to the Internet that comes it. So, as I thought about it, there's a thing called 'QS', the speed is limited to 100Mbps when you reach a certain about of usage in a day. This also differs from the services, but I get this limit if I go over 1TB for my plan, but my daily usage doesn’t go over 200GB or 300GB, this wasn't a problem at all. This wasn't even the first time, so I had a feeling after experiencing this sign. First case, the previous Studio in Gwanak used 10Gbps Internet as well, it also had a limit of 56bps for downloads by chance, and it was the only upload that showed the full speed and by finding this out by accident, so, as I contacted the customer service, and after getting an answer of 'It's going to work well again since I've reset it remotely', it surprisingly had a full speed of 10Gbps. During the process, I thought, 'Why a customer should first check the speed and let the people know to fix it?', and thinking that I got serviced with 56bps while paying for 10Gbps, I couldn't quite understand it, to be honest, but I thought it would have been a mistake, I just let this issue go back then. And the second case, after the studio moved to Mapo-gu, on the 30th of March, I tested the speed out as we installed a new router, to found out that the speed only reaches up to 100Mbps. What? I'm certainly paying for 10Gbps, but it's not even 56bps, 2.56bps, 1Gbps, nor 500Mbps, but it's being serviced with 100Mbps. I thought something would have gone wrong, so I tested out several PCs, MODEM and the router, and everything else, but the speed didn't go over 100Mbps. Thinking of it, when uploading videos on YouTube for the last week, it took very much longer than usual, and I had a thought it might have been because it's uploaded by Wi-Fi. And it took 3 to 4 hours to download a game, so, I thought that the network outside of the country is not working great at the moment. But the reason was the Internet coming in was serviced at 100Mbps not 10Gbps in the first place. Wow, that feeling of betrayal I had. But I thought it could have been a mistake, I called customer service. "Since I've reset the server and the MODEM remotely, you would have the speed back." "If it doesn't work, we'll send you an engineer." That's the answer I've got. Then when I checked the speed after half an hour, oh, it was being serviced to full 10Gbps again. Thinking about that, if it's something that can be solved remotely, it wouldn't be a problem with the devices that we have, and it was too weird for me to think about it. Or I thought it'd be hard to manage since there are so many people using it, but as I did research in 2020, there were about 150 people using 10Gbps Internet from KT. So, I couldn't really understand this, and since it's the second time, not even the first, so, I asked for a reduction in the price. "We'll reduce the price after our engineer checks it." and I got a call from a KT engineer after getting the answer. "I heard your Internet is not on the right speed, what kind of symptom does it show exactly?" "I'm using 10Gbps, but I've been provided with 100Mbps," "and I called 114 then they told me they'd reset it," "then it's got back to its normal speed." "Oh, they're doing it again. Well, I wouldn't arrange a visit for now since it's been solved." Then I called back to KT since I haven't heard anything back from them after that. "Oh, it can't be in 100Mbps since you're doing 10Gbps..." (after talking for a while) "I don't understand but I'll get you the price in between of 1Gbps and 10Gbps." What, I've been using it at 100Mbps not even at the speed of 1Gbps, "Um, then we'll check what kind of technical issues we have here then get back to you again." As a result, it wasn't resolved even I got to talk to them again, and I only got an answer that they cannot understand that I'm getting a 100Mbps speed since they've been providing the signal for 10Gbps. I told you that the engineer didn't visit me since he's heard that I got the right speed back, right? And to KT's logic, to get reduced in the price, the engineer should visit me and check the fault in the MODEM, we didn't get a visit from the engineer, and it's not a problem with the MODEM in the studio, that's why they said they cannot give me a reduction in the price. To summarize, even though I couldn't use the 10Gbps service properly, but it was organized to make it hard to get any reduction in price. I expected this to happen, when I first brought up the problem, as I checked the speed, I called KT at the same time. [A test is done in Wi-Fi 6, but it's considered normal to get at least 300Mbps.] [The speed was supported very well from the 4th time after the reset (the speed at 10Gbps, wired).] So, as they kept saying that they cannot believe it, that's why I sent an email with all the proofs. And the answer from KT was, "We don't know the reason for the speed slowing down." "That could happen since the server at KT has bugs in it." and they said, "Since we've been sending out the signal for 10Gbps, it's not a problem of KT." So, I asked, "Since this is my second time having this problem, so what kind of measures should be done if it happens again?" and they answered cannot check the slow down of the speed first," "and the solution is to check the speed every single day and call us every single time if it slows down," that was the answer I've got. To be honest, I wasn't more about getting reduced in the price, but more about hoping this problem to not happen again, and I wanted the cause and the result. But KT kept saying that they don't have a problem, and the fact that the customer should keep check the speed and call KT to solve the issue, I couldn't quite accept it. That's why after I've experienced this, I'm going to talk about why I don't [3. The reason I don't recommend 10Gbps]
recommend a 10Gbps Internet from any other companies. The first is the issue with the speed limit. Why is there a sudden 100Mbps speed limit when I pay to use 10Gbps? ["Might be because of a bug."]
I didn't hear the proper reason back until now. It's just like. "KT has sent out the signal properly and there can sometimes happen a bug, so it'll be solved if you turn the MODEM off then on again." But this is also about turning on/off the MODEM at KT, not ours. I could assume a few things since I didn't hear back with an official answer about it. If the server calculated that our Internet usage is too low, or there's a contract ID for each user in the server, and they save the profile at the speed of the Internet. Even if it's set to 10Gbps, there can be errors sometimes, and according to the words from here and there, they still have too many errors to provide services properly for 10Gbps yet. It's the second time for me. And when I heard from the engineer before he came to visit, since he mentioned that this kind of issue doesn't happen once or twice from the 10Gbps service. And according to a report from one of the subscribers, it's not a problem only of my case, nor only of KT, but you cannot doubt the quality of 10Gbps being provided across the country at the moment. The second is the issue with the providers which is because that the customer has to prove that the speed doesn't come out properly when it comes to this kind of issue. At least I had the proofs so KT replied me "That can sometimes happen if a bug occurs in the server", but before I mentioned that I have proof, KT gave me an answer being like, "KT has no problem at all, that cannot happen since we send out the proper signals," "Wouldn't that be your problem?" At least I found it quick since I like digital devices and tested out some stuff, bur normal customers barely have any chance to check the Internet speed, so, it's highly likely that they wouldn't notice the slow down of the speed and keep using the service paying the same price. And that the problem is fixed remotely in one or two minutes. If it's a problem that can be solved this easy, shouldn’t KT first spot the issue and solve the problem before a customer finds it out? The third is the issue with repairs. I assume you're not in a common environment if you're using a 10Gbps Internet, but it's hard to get fair compensation when a problem occurs in the service. The biggest problem is that if you don't ask for a reduction of the price, they don't mention it first at all. In my case, I had to ask for a reduction and that's when they tended to try, but until I showed them my proof, it was really hard to get an offer for a reduction in price. Other than the compensation, the answer that I got regarding how it is going to be solved if it happens again another time, they kept saying, "That can't happen", "We sent out the signal for 10Gbps". Didn't I send you an email with the proofs in it? 'There is no problem since we send out the 10Gbps signal properly.' That's the kind of answer I've got. And when I asked what measures can be taken if it happens again, they asked me to call them back if I find a problem by checking the Internet speed every day. That's the answer I've got. Lastly, the fourth, there're issues with the poor 10Gbps devices for now and the information about it. This is additional stuff, but one thing that I couldn't trust was that... I have experienced installing 10Gbps Internet from all of SK/KT/LG U+ to test them out. There was not much information about 10Gbps when I called the customer service, but the engineers who installed 10Gbps, none of them had a device to check the 10Gbps speed. And they asked me if I have any device using 10Gbps, so, I had to assemble a PC that can use 10Gbps, then connected 10Gbps Thunderbolt to MacBook to check the speed. So, the network company didn't take a device to check the speed, but they checked if the speed comes out to find with the customer's devices, that was the process that I couldn't really trust. Regarding the quality and especially the service of the network outside the country, it’s decent from KT, that's why I trusted it a lot. But there was a sudden speed limit which has to be first found out by a customer, and not promising the right compensation and a future development is a big problem in my opinion. If I can use 10Gbps properly but with a bad service I can keep using it considering it has at least a good speed. But there were circumstances that I cannot even use 10Gbps at the speed of 1Gbps, and it's all the customer's job to prove it. I can never recommend it. So, I don't recommend using 10Gbps service for now, but if you are in an environment that requires 10Gbps, do check if the speed comes out at 10Gbps properly on a regular basis every day, and if there's any problem with it, go ask for a reduction. And you have to collect the proof in advance, and instead of fixing it remotely, ask for a visit of an engineer and figure out and get the answer on the spot. KT actually recommended me like this as well. Anyway, this is it for today, I wasn't satisfied with the quality of the Internet from KT, so, for the 10Gbps service that is currently being provided in the country, rather than having the service as a mere formality, but for the people who actually use the 10Gbps service, I hope they provide more detailed care and prevention of the reoccurrence of the problems. What's interesting if I think about it, this cover should be fixed with screws, but the 10Gbps that I recently installed, the engineer left the top open.
