China Practically Unreachable By Western SMS?
Ainsy writes "A friend of mine recently began a placement as an English pronunciation teacher in China. She has picked up a pay-as-you go sim for use over there, only to discover that China seems to have been almost completely overlooked by international communications agreements, specifically from the UK. A bit of snooping tells me that Vodafone is the only network from which it is possible to send SMS to a Chinese registered mobile phone. SMS in China is upscaling massively, and is incredibly cheap currently — even 'premium' SMS info services cost 1 Yuan (that's just £0.081 GBP). I'm curious why such a large section of the world market is cut off from the west's wireless communication networks especially with the recent Olympics putting the spotlight on the nation in general.
China mobile is the world's largest carrier ranked by subscriber base (415 million) and isn't even the only carrier to operate in China). There are a few websites around from which SMS can be sent to China for a fee but this is of only limited use when on the move. Can anyone tell me why this situation has come about and when we can expect this sort of service to be enabled?"
China Telecom & China mobile are no longer actual monopolies, but still control enough of the market to be very monopolistic in nature.
You can expect SMS interoperability...never, and the last I heard, they were pissed off with the potential of skype-like services cutting into their profits and were going after skype-out with great vengeance and furious anger.
Actually most of the "Chinese" spam does not originate there. It's paid for by American spammers, to sell American products. See the ROKSO list if you have any doubts.
Oooh, scary. Did you even read the summary? "A bit of snooping tells me that Vodafone is the only network from which it is possible to send SMS to a Chinese registered mobile phone." If it's already possible via Vodafone, that indicates it's a business rather than government issue.
The parent has it all wrong. Like many things in China, to the untrained eye it looks like some direct attempt to refrain free speech. In reality it's completely economic...
China Mobile _could_ allow anyone to send for free on their network, but frankly, very few people (relatively speaking) care. In a country so big and self-dependent, international texting doesn't matter.
Opening up free internet based SMSs does little other than open up a HUGE hole for people to commercialize on China Mobile's service. China Mobile, being a government owned corporation, wants to ensure that it holds a monopoly on innovation on its network. This is largely why you see very little new things in terms of SMS happening in China, because if someone attempted anything, China Unicom would simply block their service and duplicate it.
It's not about rights, it's all about money
PS: Skype can send to Chinese phones (I'm in China so I've looked into this)
In the USA, it's also legal to use a pay phone or a prepaid phone call without revealing your identity. You will reveal your location, so make sure you call from a relatively populated place that is devoid of cameras.
For some, anonymity is a valuable commodity: Some people are willing to pay $10-$20 for a single phone conversation in exchange for anonymity - that's the approximate cost of a cheap prepaid cell phone with 10-20 minutes of talk time.
No, you're buying an illusion of anonymity. With modern call log pattern analysis systems, intelligence services can determine your identity from your calling patterns, not the number from which you happen to make the call. The rough geographical location they get from the cell phone companies is just the icing on the cake. This kind of pattern matching is well suited to automation and it wouldn't surprise me one bit if every cell phone in every country with a decent intelligence service was subject to such analysis.
One would also expect pre-paid "anonymous" cellphones to be subject to additional "identity guessing" analysis since they are an obvious option for "anonymity" that the naive crook might take. With a bit of data sharing and international cooperation, I bet they can track people as they move around the world from cellphone to cellphone.
Basically, if there is any kind of pattern at all to your cell phone use - and there almost certainly is - cell phones are not "safe", no matter what. The same, of course, goes for people thinking that going to an internet cafe and thinking that their web browsing is somehow hidden. Fact is, if you log on at an internet cafe and then do the same 10 things you always do, that narrows the scope of your likely identity down like 6 orders of magnitude. Wow, thinks the computer, this session at this net cafe looks very similar to the guy at this home address. And boy, it's geographically pretty close. Likelihood: 85%. Save.
If someone is watching at the telecoms/ISP level, and you can be sure they are if you're in a UKUSA country, then your identity is likely derivable from patterns of usage, not the registered owner of that IP/number/whatever.
Sucks doesn't it. Anyway, it is possible to communicate anonymously, but it's a lot more work than just buying a prepaid. In fact you basically cannot use the phone system at all. You have to think a lot more like them, though, if you really want to escape the pattern matching dragnet.
On the bright side, SIGINT is pretty high level stuff. The intel agencies are not going to be giving away this kind of info to the police, who will just overuse it and kill the golden goose - at most they'd send a tip or two in politically important cases, I guess. One would hope that the top-level intel agencies are fairly responsible with the awesome data they have and you'd have to be a pretty bad guy for them to actually act on info from pattern matching surveillance.
Let my new 7-digit UID be a lesson to all - write down your passwords.
