First impressions: Yes 4G network performance and the Yes Go 4G dongle

Posted:  November 22, 2010   By:    40 comments   

Things are starting to turn around for Yes. After a poor start off the blocks in this ridiculously competitive telco race, the new contender is looking like it might be able to keep up with the pace.

After receiving an email confirmation that our pre-registered account has been activated, we were finally able to log onto the Yes network with our Yes ID. And with that we immediately started on some performance tests of the Yes network and the Yes Go 4G dongle.

So here it is our first impression of Yes 4G network while using the Yes Go dongle.

At RM99 with RM100 pre-loaded credit, the Yes Go 4G USB dongle offers the lowest entry point into the Yes 4G network. The Go has drivers for both Windows or Mac but we’ve gotten reports that they are some issues when running the device on a Mac.

We like the packaging of the device. It’s simple and uncluttered. Inside, you get the slim dongle and an installation guide. On the device itself, a label behind reveals that the Yes Go is made by Informark — a Korean WiMAX equipment manufacturer — that carries the model IMW-U300. A quick check at the informark site reveals the IMW-U300 Go looks remarkably similar to the IMW-U100 dongle that informark advertises. We’re not sure what the differences are between the two but we will try to find out.

Weighing in at 16g, the Go feels very light and judging by its weight alone, you might think that the device is hollow dummy set. This is a good thing considering the fact that you’ll be carrying the Go with you but it doesn’t bode well for quality as it feels rather cheap — simillar to to the original W1GGY.

The foldable USB head is stored neatly into the body just like P1’s WiMAX’s older W1GGY and it flips out up to 270 degrees to the back. When compare to the W1GGY, you’ll immediately notice how much smaller the Go is. Forget about comparing it with P1’s so-called Super-W1GGY as it’s plainly obvious that the Go is much, much smaller and doesn’t need a cable or a suction cup.

Spec wise, the Go operates on WiMAX at 2.3GHz which is the allocated WiMAX frequency in Malaysia with channel bandwidth of 5MHz, 8.5MHz and 10MHz. The device has a rated download peak speed of 30Mbps and uplink of 6Mbps.

Installing 4G Network Manager

Before you can connect to the Yes network, the USB dongle boots up the set up file of its “4G Network Manager”. Installation was a breeze, with just four you’re ready to connect. We also like the look and feel of the connection manager but it didn’t have the option for us to look at the signal strength and quality — the RSSI and CINR values (Update 24112010 0107hrs: Turns out you can check the RSSI and CINR values under settings where there’s a tiny button on the top right marked SYSTEM INFO).

To connect to the Yes network, the Go Network Manager will first search for coverage around your area. If there is coverage, the signal strength will appear on top represented by the number of bars. To proceed, just key in your ID and password then click connect. The whole process from searching and logging in took less than 30 seconds and we’re able to connect to the Internet.

We compared this with the P1 W1GGY and Super-W1GGY and found that the Go, beats both hands down on the speed in which it is able to detect the network and also the speed in which the computer can detect the modem. The go does offer speedy connectivity.

Just for fun, we also compared the network detection performance of the Go and an MSi WENB. The Go was pretty close to the network detection time of the WENB. Considering that the WENB has a WiMAX chip embedded right on the motherboard itself, the Go’s performance is amazing.

If you’re a highly mobile user who needs to send out emails quickly, you’ll appreciate the fast start-up of the Go. We know we did.

Yes Internet experience
Unfortunately our initial test location (Taman Shamelin Perkasa, Cheras) had very little coverage with the Network Manager showing between 1 – 2 bars in signal strength. This could also be related to the fact that we conducted our tests from the 17th floor of the apartment building that we’re in.

Side-by-side with the our W1GGY tested at the same location, we were able to get the same number of bars (between 1 – 2) but we were unable to get connected to the network.

Despite the less than optimal network coverage, we proceeded with the test anyway. As you can see in the speedtest pictures posted below, the download and upload speeds are pretty impressive. However ping seems to be inconsistent locally with some showing under 100ms while international sites clocked around 300 ms.

Seri Kembangan


Kuala Lumpur


New York

Los Angeles

We’ve also done speedtest using other ISP’s tools from Maxis, P1 and Streamyx with screenshots at the gallery below.

Comparing to other 3G networks, we averaged DiGi at 1Mbps download and 300kbps upload, with U Mobile we got roughly the same speeds. Maxis performance at our location is appalling delivering dial-up speeds. We don’t have a Celcom account to test so weren’t able to compare Yes with that.

But do bear in mind that this is a virgin network with very little number of users per site, so you should expect these good, solid speed right now. The real test will be if Yes could deliver this consistency at the load increases with the number of subscribers. But having said that and having test other virgin networks before, we can say that these results are amongst some of the more impressive ones we’ve seen.

Unlike other operators, Yes never specifically advertised about its speed figures, instead it generalises that subscribers can expect up to 3 – 5 times the speed of 3G. We find that 3Mbps download is roughly three times faster than what normally get on our 3G HSDPA connection at our location. Effectively, the 3 – 5 times faster than 3G claim is substantiated.

What’s more surprising is the upload speed of 2.75Mbps clocked in the speedtest which definitely is the fastest upload we’ve seen on a mobile broadband. Of course speedtest numbers may not necessary reflect actual usage. So next we tried to do a couple of download test.

For a single thread downloads, we got about 150KB/s to 180KB/s on average which we find is pretty decent. To test out the max download throughput of the Yes network, we did a multi-thread download test and the results were even more impressive.

Downloading using FDM started pretty low at 180KB/s but that progressively went up to an average of between 500-600KB/s which equates to a connection speed of just under 5Mbps.

Next, we tested video streaming on youtube and that delivers smooth experience free of any buffering even when we bumped up the video to 720p. However when pushed to view 1080p videos, signs of buffering start to appear due to its higher bandwidth requirement. Nevertheless, Yes still delivered impressive speed and consistency.

First impressions
While we’re pretty happy with Yes in terms of its performance, we must once again point out that this is a virgin network with very little load and a small number of users users on the network right now. As with almost all networks of this kind, it is normal to see good performance. The real test will come when the network gets loaded with more and more customers. The speed and consistency of the Yes network in the long run will be dependent on their network and capacity planning to cater for user growth. So to know if this new network is really good, we will have to wait and see.

The tests that we’ve conducted in this first impression are just preliminary to test the basic performance of the network. We’ll have a more thorough test at various locations soon to see if Yes does provide consistent experience all round.

While we are doing this, please let us know if you have a question about the Yes network we’ll try to have it answered.

Thanks for the review. Can you guys try to test the performance while on the move (eg train or car)? Perhaps also see how well the YTL base stations handle handovers 🙂


    Thanks for visiting. In fact we did a test on a moving car. Watch out for a post on this tonight. 🙂

Can you try at 120KM per hour? Does it disconnect when you move places?


this is fantastic news.

despite all the bad articles on your site, i have many friends who have nothing but good things to say about Yes and YesLife in particular. Teething issues are bound to happen. Once this stablises, it will be very hard to beat.

while the Go is impressive, i think the Huddle is the ace in the pack for Wimax/Wi-fi on the go.

10Mbps mobile speeds around KL and PJ is simply amazing. i am going to say YES!


    I can't factually substantiate this, but when I enquired about the Huddle, the seemingly knowledgeable YES sale supervisor (not the flagship) was frank and honest to me by saying that the Huddle is showing poor performance in receptivity. While the Go is displaying 3 bars of reception, the Huddle can only cough out 1 bar at the same spot . He advised me to hold on unitl a new firmware is in place to rectify this problem. BTW, YES outlets kiosks will not be offering the Rm1199 Huddle package until the following month, save for the flagship in LOT 10. I've been told they are ironing out some issues between YES and its partners.


This is like unifi prepaid mobile version. Please test in more area, I'm planning to dump my maxis broadband for yes. How is the hudle?

Would love to see the speed comparison of both yes modem.


nice one guys. looking forward to more detailed tests. thanks.


    Thanks! More coming soon!


Thank you for the great write up !!
Just wondering if you could make a cost comparison
btw Unify/Streamyx and P1 with regards to casual to heavy users.
Thank you once again and looking forward to more reviews.


Did you manage to test voice call? Also for charging, is it in a block size of 3 MB per 9 sen ? e.g. if I login and uses 1 MB only before logging out, I still get charge 9 sen?


    Unfortunately we can't as due to interconnect issues with certain numbers. Our number is the affected 331/332 range. Once this has been resolved, we will test and share it with you. On the data, if not mistaken they calculate by MB. So if you use 500KB, you pay 3 sen. If you use 1.01MB, you pay 6 sen.


i heard that many ppl are having difficulties to login into their yes ID and YES website is down for hours because of some foreign attack into their servers. is this major problem fix?


I would like to congratulate YTL on a fantastic job in getting this WIMAX out. Of course one would expect initial problems as it is not easy to be the trend setter especially in sorting out humangous technicalities. Internet and phones are not going to be the same again. Well done YTL.


    I agree. This is the world's first converged 4G service with voice and data in one plan. And despite the growing pains, it works, and works well too once issues have been ironed out. We Malaysians never are one to encourage the good things that come out of our own country, but are so quick to criticize.

    Kudos YTL for having the guts to put your money where your mouth is. If it doesn't work, we know you tried and the fact that your money is on the line speaks volumes for the courage that you have standing against all the telcos who are raping money from the Malaysian public.

I don't like the pricing. PAYU is not good. If P1 we download 100GB per month also pay RM99 only. Once limit reached, they throttle the speed only, no need to pay extra. If Yes, how much we need to pay to download 100GB?


The connection keeps disconnected, speed flunctuates..very unstable. Fed up with the connection issue. Not going to say Yes now..


wow… this look great…
love saying yes… keep me continue saying yes ya, YTL gor gor… 🙂

sharing is caring… thanks to
but sharing also scaring too… (other telcos outside there, you hear this…lol)


hi, thank you for the info on YES 4G…. i would like to know about the price. Are we only paying for the usage or do we need to pay RM30 every month (as some people mentioned) + usage. Could you test the speed at bayu Puteri Apartment in PJ? Moreover, I visit sites such as youtube and PPTV a lot, is YES a good choice? Thank you…


    Well Yes say its Pay as You Go but at the same time you are tied to a minimum of RM30/month. On testing, we will do as much as possible.

    If your usage is a lot, exceeding 3GB, Yes might be too expensive. You can check out the cost comparison here:…

    For heavy users, we recommend fixed broadband like UniFi/P1/Streamyx which is cheaper per GB.


      hi..Thank you for your reply. I am not too sure how much GB i used in a month but I will consider those fixed broadband that you have mentioned. Tks again 🙂


        No worries. Always happy to help out. Thanks for dropping by 🙂


can anyone give me the installer? cannot get from yes website

zack pandan

Whoa! Great review soyacincau.. and great price comparison review too! I'm a heavy user so I'll stick with Streamyx for now. Furthermore, it is not exactly pay per use as it claimed, as user is required to maintain min RM30 per month. But the no contract part is quite interesting. Cancel whenever you want unlike other ISPs that insist you sign up for 12 mths contract.
Might consider for my mobile though

Yes 4G: KL Road Test | SoyaCincau

[…] Earlier, we took with the Yes Go USB dongle for a spin and we’ll be the first to admit that we were quite impressed with what the Yes network has to offer. In our stationary tests, we managed 5Mbps downloads and 2Mbps uploads with only two bar reception with the test done on the 17th floor. We know that the network is still new and there’s still very little load on it but even by this measure the speeds that we’re getting are rather impressive for a wireless network. […]

U're Absolutely right, I am pretty impressive with the speed performance but let see when it's get more subscriber at that time!


my speedtest result, location shah alam bukit rimau/kemuning.


Just went to setiawan/Sri Manjung & gua Tempurung over the week end. From gua tempering to Setiawan no yes coverage. Was able to get Digi Mifi to work tho.

Have you try out yes life? I tried using the address book to add some friends ( want to try yes SMS ) manage to put in 1 contact after a long time. Failed to add in more contact. Please do a write up on this as yes did advertise on a 9 cents SMS package.


I'm using ' go 'also, but when I'm using it non-stop for two days, it give me an error on 'Yes' server, the error is, 'Yes is out of credit', but I still had Rm100.00 credits in my account, still the same error I get the next days, I can connect to Yes server but cannot browse! I think IMW-300 can't stand the heat when we use it for the long period, what about you? haven't you test it by using it to a long period, especialy downloading a big files.


Hi Soya,

Thanks for your complete review on YES others as well. Im planning to subscribe to YES because I hate this Fair usage thing with snail speed. Currently im using Celcom Bb the 98 one, i wonder how is the Yes speed doing now. I am also a torrent lover, is it wise for me to change to Yes?? If speed my priority.

Btw, does Unifi have prepaid service now?

And what about TIME..i saw thier banner by the road recently, any news on them.

Hopefully u can help me on this.

Thank you once again for your hardwork.

[…] for some speedtests done on YES, they have managed to obtained speeds of 6Mbps in Kuala Lumpur (here, here and here). Even at 3Mbps, it is definitely faster than my current P1 Wimax Home Lite or Maxis […]


I have a YES but its weird that i cant login to certain website of other campus. did u know how to solve this problem?


I sign up for the huddle and the connection is not working in kinrara and kl jalan seamark 90% coverage I don't think so. I have been down to lot 10 4 times to try to
Settle the issue but yet it persist waste of time and money. My experience with yes "Yes it's totally crap over claim"


can you test the connection at taman kosas, ampang?


if im upload a file, does it calculate as usage data?


    Yes it does.


Hey Soya Cincau, I'm a YouTuber so uploading is more important than downloading for me. I generally upload about 2GB/video everyday so can this dongle thingy support my job? I'm sick of the upload speed streamyx gives me. Hope you'll reply. Thanks 🙂
