AIS vs DTAC vs Truemove (True-H), technical info for IT nerds/nolifers

fdsa · October 26, 2021

Top tier: DTAC

- does not MITM* any port

- ping times to Europe is ~200ms (I don't remember numbers for sure but they were lower than with Truemove)

- connection is stable, does not disconnect randomly

- normal IP score ratings (was getting google/cloudflare captchas quite rare)

Low tier: AIS (one-2-call)

- MITMs port 25, other ports [seem to be] OK. Note: AIS BLOCKs all connections to port 25, see below**.

- ping times to Europe is ~200ms (190-240 to France)

- connection is stable, does not disconnect randomly

- [I don't know IP scores yet as its the first day I use AIS lol]

Shít tier: Truemove (True-H)

- MITMs ALL PORTS. Note: True-H seems to intercept connections to port 25 but still allows outgoing traffic, see below**.

- ping time to Europe is ~300ms (250-350 to the same server in France at the same time with AIS test)

- connection is unstable, randomly disconnects from few times to few dozens times every day

- low IP scores - dirty subnets, google/cloudflare captchas appear VERY often

The connection speed is OK with all providers, I've used 4mbps and 10mbps tariffs, was getting 4-10 mbps on all of these SIM cards.

* - if you are not a IT nolifer and don't know what MITM is:

if you connect to random (even not existant) IP address and random port that must be definitely closed and get "connection success" - it means that the Internet provider is intercepting all your requests and records or modifies all your traffic. It could be done for completely legitimate purposes (e.g. to fight agains SPAM) or for malicious purposes (to spy on you or to do some other nasty stuff e.g. replacing your sent messages with a different text)

and now the details for nolifers:

Example with Truemove:

$ telnet 1.2.3.4 25

Trying 1.2.3.4...

Connected to 1.2.3.4.

Escape character is '^]'.

with AIS:

Connected to 1.2.3.4.
Escape character is '^]'.

452 syntax error (connecting) <<<<=== that's me pressing Enter many times. "452 syntax error" is a reply from internet provider's MITM server

with DTAC:

Quote

$ telnet 1.2.3.4 25
Trying 1.2.3.4...
telnet: connect to address 1.2.3.4: Connection timed out <=== this is the correct reply so DTAC does not intercept connections

Truemove intercepts absolutely all connections even to not existant IP addresses and ports:

Quote

$ telnet 10.20.30.40 1234

Trying 10.20.30.40...

Connected to 10.20.30.40.

Escape character is '^]'.

AIS intercepts connections to 25 port only (but even to not existant IP addresses):

Quote

$ telnet 10.20.30.40 25
Trying 10.20.30.40...
Connected to 10.20.30.40.
Escape character is '^]'.

Quote

$ telnet 10.20.30.40 26
Trying 10.20.30.40...

telnet: connect to address 10.20.30.40: Connection timed out

DTAC does not intercept any connections at all, even port 25:

Quote

$ telnet (my-server-where-25th-port-is-definitely-closed) 25
Trying (my-server)...
telnet: connect to address (my-server): Connection refused

** - concerning the "raw" outgoing emails:

DTAC does not mess with connections and shows the full banner:

Quote

$ telnet (my-email-server) 25
Trying (my-email-server)...
Connected to (my-email-server)
Escape character is '^]'.
220 (my-email-server) ESMTP Exim 6.6.6 Tue 26 Oct 2021 08:00:06 <=== full SMTP banner
220 this system does not allow bulk/unsolicited emails

True intercepts the connection and shows incomplete output!

Quote

$ telnet (my-email-server) 25
Trying (my-email-server)...
Connected to (my-email-server)
Escape character is '^]'.
220 this system does not allow bulk/unsolicited emails <===== only a part of SMTP banner appears! the first line of the banner was deleted by Truemove MITM server

AIS intercepts all connections to port 25 and does not show any output at all:

Quote

$ telnet (my-email-server) 25
Trying (my-email-server)...
Connected to (my-email-server)
Escape character is '^]'.

<===== SMTP banner does not appear at all!
452 syntax error (connecting) <=== thats me pressing Enter several times. "452 syntax error" is a reply from internet provider's MITM server
452 syntax error (connecting)
452 syntax error (connecting)

421 too many errors
Connection closed by foreign host.

--- if you need a mobile internet provider for professional work - go with DTAC.

Mid tier: AIS

. . .

- connection is stable, does not disconnect randomly

unfortunately it appeared to be not true, today AIS was disconnecting for the whole morning:

Oct 27 10:17:37 lap ModemManager[143515]: <info>  Simple connect state (8/8): All done

so DTAC is the most stable mobile internet provider.

OMFG, I've just noticed that AIS drops ALL traffic to 80 port.

$ curl -v (my-server.com)
*   Trying (my.ser.ver.IP):80...
* TCP_NODELAY set
* connect to (my.ser.ver.IP) port 80 failed: Connection timed out
*   Trying (my.ser.ver.IP2):80...
* TCP_NODELAY set
* After 84779ms connect time, move on!
* connect to (my.ser.ver.IP2) port 80 failed: Connection timed out
* Failed to connect to (my-server.com) port 80: Connection timed out
* Closing connection 0
curl: (7) Failed to connect to (my-server.com) port 80: Connection timed out

ports 79/81 immediately reply with "Connection refused", as it should be, and port 80 hangs for some time and then fails with a timeout.

Of course it's not only my website - same problem with google.com and every other website. Only port 443 (https://) works for the web browsing.

And this fact moves AIS down to the shít tier, next to True-H.

Update: today port 80 works well, possibly such limitation is set up on selected IP subnets only, so if you experience the same issue - reboot your modem to get a new IP address. Works for me on subnet: 182.232.46.0/24 (182.232.44.0/22?)

Concerning the random disconnects: AIS does randomly disconnect but much rarely than True-H (still more often than DTAC) - from 0 to few times per day, while Truemove guaranteed to disconnect at least twice daily, and up to a dozen of times. Usually Truemove disconnects at the night time, I believe their billing system does that to calculate the used traffic.

Also for statistics: I don't see any HTML injections into the plain HTTP traffic.

Yet another update:

Yesterday port 80 (plain HTTP) did not work on subnet 182.232.18.0/24 (182.232.16.0/22?) with all websites I tried, but today I still have the same IP address and port 80 works well with all websites, so this blocking seems to be random.

Concerning the random disconnects: sometimes I have no disconnects for several days in a row, and few days ago I had ~20 disconnects in 1 day. Still much better than TRUE-H.

And for statistics: still no HTML injections into the plain HTTP traffic.

So, to sum up: DTAC is definitely the best mobile provider, Truemove "TRUE-H" is definitely the worst, and AIS is "somewhat ok".

Hi @fdsa, even as someone who used to work in IT support, most of this goes over my head ????

However can you advise; I'm looking at getting a 4G router from Aliexpress. I found suppliers in Thailand only seem to sell old Cat4 models with crappy 11n wi-if.

For not much more I can get a Cat19 Huawei B818 from China. I just want to make sure it'll work in Thailand.

Do you know what 4G frequency bands are used here (B1/3/5/7/8 etc)?

Cheers.

There are many different models of the same router, which support different network bands. Look for the model intended for Australia, it should work well in Thailand too.

For your device - B818-260 or B818-263 should work:

B818-260 - has USB port (easier to flash firmware), bands 1/2/3/4/5/7/8/20/26/28/32/38/40/41/42/43/66

B818-263 - does not have USB(will be harder to flash), bands 1/3/5/7/8/20/28/32/38/40/41/42/43

Btw it seems to be Cat12, not Cat19.

muratremix · December 13, 2021

What about fixed internet connectivity? Truemove had transparent proxy before, I bet they still do. 3BB has MITM proxy for port 80 for State enforced blocking of websites, but 443 / HTTPS was fine.

Thanks I was looking at either B818 (which I think is Cat19) or B628 which is Cat 12. There's only about £10 difference between them and both a lot cheaper than in UK whihc is a bonus!

That was definitely my first choice, but I'm kind of struggling with the language barrier finding out what's involved.

The condo I'm renting despite it being built about 6 years ago hasn't had fibre installed. So I think it'd need cable run and holes drilled in the wall etc?

The building has free shared wi-fi which is actually fine (at least while there's not many people living here). Obviously I'd prefer my own unlimited fibre for 600 baht a month, but if there's another 6,000 baht installation fee on top I'm not so keen as I'll probably only be here for another 10 months.

fdsa · July 30, 2022

Fun fact: AIS "1 year SIM" lasts for 9 months :biggrin:

I've activated my SIM on 15th Oct 2021, and today 30th Jul 2022 I've got these two SMSs:

AIS
Your full speed Internet has 200MB remaining. After used up, get unlimited usage at reduced speed based on your package. To subscribe package, http://www.ais.co.th/netpackage/5g/
AIS
Your internet usages have been used up. To continue 5G max speed internet, just 99B. 4GB 7days or 150B. 9GB 15days, click http://www.ais.co.th/netpackage/5g/

ok nvm, gone shopping for yet another DTAC SIM.

// EDIT to clarify: I have "unlimited traffic" SIM, not "unlimited speed" one. And today my speed dropped down to ~100 kbps from tariff's 10 mbps.

my bad, I didn't notice the MNCs are different and thought that all of them are AIS.

So AIS (MNC 03) indeed uses bands 1,3,8,41; and I haven't found who uses band 26 (MNC 09) with short googling.

No idea why there is no DTAC because I have DTAC SIM in my phone lying next to the laptop which has AIS SIM, and the phone has good LTE signal and working internet connection.

So this post was a mistake? You are just describing the AIS Marathon SIM after you have utilised the 100 GB allowance for the month.

You can get a new AIS SIM and apply an Unlimited 8 Mbps pack to it for 150 baht per month, comparable in price to the Marathon pack.

Though obviously you still have a few months to go on the Marathon pack, if that is what you have.

DTAC currently have 15 & 30 Mbps annual SIMs from 1400 and 1700 respectively.

Bruno, what was your info source/sources for your post back in December listing the various LTE and 5G bands of the three major mobile providers?

I noticed you listed only 5G 700 Mhz as the sole 5G spectrum for both DTAC and AIS... I thought one or both of them also were using some other bands for 5G?

https://www.gsma.com/membership/resources/dtac-and-true-merger-talks-point-to-a-need-to-address-unequal-footing-in-thailands-5g/

"In February 2020, NBTC assigned spectrum for 5G use across low (700 MHz), mid (2,600 MHz), and high (26 GHz) frequency bands."

"AIS launched 5G NSA (non-standalone) in February 2020 using the 700 MHz, 2.6 GHz and 26 GHz bands, followed by 5G SA in July 2020 in cooperation with Huawei. AIS deployed 5G CA (New Radio Carrier Aggregation) by integrating its mid-band (2600 MHz) and low band (700 MHz) spectrum."

"AIS and TrueMove H deployed their initial 5G networks on the 2600 MHz spectrum, while dtac used frequencies in the 26 GHz band."

"AIS and TrueMove H deployed their initial 5G networks on the 2600 MHz spectrum, while dtac used frequencies in the 26 GHz band."

Currently:

AIS:

5G NR Frequency Bands

n28 (700 MHz)

n41 (2500 MHz)

n258 (26 GHz)

DTAC:

5G NR Frequency Bands

n28 (700 MHz)

Truemove H:

5G NR Frequency Bands

n28 (700 MHz)

n41 (2500 MHz)

DTAC use of 26 GHz was not for general public consumption.

So this post was a mistake? You are just describing the AIS Marathon SIM after you have utilised the 100 GB allowance for the month.

not a mistake - I've purchased that SIM in October 2021, and activated it on 15th of October.

The tariff is limited speed (10 mbps) with unlimited traffic.

...or the "unlimited traffic" SIMs from AIS are not actually unlimited?

What do you see(SMS) when you use this USSD code? *121*32#

Well, you are right -

- the "unlimited" SIM from AIS appeared to have a 100 GB traffic limit ????

They weren't selling annual unlimited 10 Mbps SIM at that time last year. Their last annual offer was unlimited 8 Mbps. So it was either that or the Marathon SIM you had.

Marathon SIM it is.

OMFG, I've just noticed that AIS drops ALL traffic to 80 port.
$ curl -v (my-server.com)
*   Trying (my.ser.ver.IP):80...
* TCP_NODELAY set
* connect to (my.ser.ver.IP) port 80 failed: Connection timed out
*   Trying (my.ser.ver.IP2):80...
* TCP_NODELAY set
* After 84779ms connect time, move on!
* connect to (my.ser.ver.IP2) port 80 failed: Connection timed out
* Failed to connect to (my-server.com) port 80: Connection timed out
* Closing connection 0
curl: (7) Failed to connect to (my-server.com) port 80: Connection timed out
ports 79/81 immediately reply with "Connection refused", as it should be, and port 80 hangs for some time and then fails with a timeout.

Of course it's not only my website - same problem with google.com and every other website. Only port 443 (https://) works for the web browsing.

And this fact moves AIS down to the shít tier, next to True-H.

ffffffffff...........

did I say already that I hate AIS? This filtering of all port 80 traffic is driving me nuts, plus their horrific problems with internet connection to Europe and lack of any response makes them even worse than True-H.

Is there any other mobile provider worth trying? I have a few DTAC SIMs already and thus need a backup provider to diversify my connections.

Wow, very interesting offer, thanks! Unfortunately my modem does not support Band40 (and the one I'm planning to switch to does not support B40 too ????‍♂️)

Your final choice is My by NT(formerly My by CAT): https://www.mybynt.com/th/PrePay.php?package=217_เน็ตสุดคุ้ม-เล่นได้ไม่อั้น-4G

679 baht for 62 days of 8Mbps is the current promo on that page. But don’t bother choosing from there. Go to their Facebook page. There you can find unlimited 15Mbps for 359 baht including calls, 319 for 12Mbps, 239 for 10Mbps..

They also have a product similar to AIS Marathon but for 1490 baht; 100GB @ 15Mbps etc
Another promo if you don’t need high speed is 100 baht per month for with unlimited 2 Mbps or 30GB of 4Mbps.

They’ll either be like Truemove H or they won’t. I guess you’ll find out and let us know here ????????

My by NT are on Bands 1 & 3. You can pick up a Cat.6 portable router that covers those bands for around 1300 baht currently. Though perhaps your needs go beyond a simple portable router.

Thanks, I'll check these "My" SIMs out.

I have a 4G modem in my laptop and a usb modem for the WiFi router, both Cat6.

My needs are very simple: do not block any of my traffic (I can understand port 25 but why the hell AIS drops plain text HTTP traffic?!) and have a stable connection with European servers. Not necessarily fast - 5 megabits/s would be plenty, and so far only DTAC matched these needs.
