T-Mobile Releases New Card, Outlaws VoIP and IM

An anonymous reader writes "T-Mobile has launched a new 3G data card in the UK, and banned users from using it for VoIP or instant messaging applications." From the article: "Lock cast doubt on the sustainable viability of a mobile operator banning VoIP from its network. 'I think that eventually, if there's customer demand for this, it will happen," Lock said. "Other organizations will come along allowing VoIP. Who do you think is going to win?'"

So this gives possibilities of a data-usage plan which allows VoIP, or when the service finally rolls out, the company will simply drop this restriction if the trial indicates a negative support.

      I don't know why VOIP would be functionally useless above 150ms unless it was designed incorrectly. I routinely have longer round trim latency than that on my cell phone calls from California to Tennessee, and that's basically POTS most of the way.

      Right -- a tenth of a second is nothing. I live in the South Pacific, and calls to the US on the POTS have a noticable delay -- at least 1-2 seconds. On the other hand, my ping times to the US average about 400MS, I have no problems using VOIP, and the discernable delay is usually less than that of POTS, if it's perceptible at all.

      At any rate, delays over 1 second can be irritating, but are still "functional." Unless your conversations are often mistaken for auctions, any delay less than 1s should be largely transparent.

      150ms is only the network delay time between the two devices.

      Don't forget that the audio needs to be encoded, packetised and transmitted. Then received, the packets re-assembled in the right order and then decoded back to an audio stream. So it's incorrect to equate 150ms network delay time with 150ms speech delay time on a mobile or standard telephone.

      150ms is the recommended maximum network delay for VoIP traffic as any more than that and you start to get noticably annoying delays. You might be happy to put up with delay on your phone calls but a lot of people aren't (i.e. managers, salesmen, me etc).

      Also, I doubt a call from California to Tennessee would travel mostly over POTS. I'd say the call would be over more advanced infrastructure than 2 copper wires, and in fact you're probably going over a VoIP WAN link at some stage.

      Additionally (in reference to another post by someone else), you shouldn't get a delay of anywhere near 1 to 2 seconds on any (well, to be honest, most) telephone call to anywhere in the world. That is extremely unacceptable delay and carriers would want to know if you're routinely getting this sort of delay. I agree it does happen occasionally but usually only when the default routes are down or fully used and you end up getting routed around the world a couple of times or over a poorly configured IP trunk. If you do get a call with this much delay, hang up and call again. You'll probably find the default routes have freed up by then and you will usually get a better quality line. Usually. :)

      I was testing an E&M voice tie line from Sydney to NY. One of the tests we performed was to loop the NY end so I could hear my speech in the receiver. The delay was at worst 1 second. Sydney to NY and Back, around 1 second delay over 4 copper wires and various other network infrastructure in between.

      The way it works in the states is... you have a choice between SMS and I believe "T-zones" is what it's called..... internet service basicly. SMS gives you access to Aim-ICQ/MSN/Yahoo for a fee per message, or you can get it at a flat rate for a tad more. You can pay extra to get unlimited text messages, or you can go with a data plan and, if you have a phone that supports it, run a true blue IM client on your phone. T-Zones costs a little more than unlimited SMS, not all phones support it, but you can login to multiable services at any given time. The SMS version basicly relays your messages though their standard text message service.

      The artical isn't clear on this subject, but I imagine you can still have your IM, just so long as you use it through their SMS network, a fee per message deal or additional subscription. Just a true blue IM client is banned... which I suspect it's because it simply can NOT be metered.

Last time I had ATT, they suddenly decided that my house was located in a "roaming" area and charged me 50 cents per minute for using my cellphone.

    At least T-Mobile is being pretty up front about the whole thing -- not allowing IM and VOIP is strictly a business decision. They've concluded that most business users aren't heavy users of IM and VOIP, and by not offering these services, they can prevent non-business users from signing up. I bet its more to make sure they don't oversubscribe the network more than anything else. Allowing VOIP and IM would probably more than double the number of people who'd want to sign up.

  19. 150ms is fictional / misunderstanding by billstewart · · Score: 4, Informative
    First of all, the 150ms recommendation was originally for in-continent calls - the standards people recognized that transoceanic calls might need to be as long as 400ms, and that's still better than satellite. Remember that the speed of light in fiber is about 8-10ms per 1000 miles, depending on how straight your fiber routes are (it's a "miles of fiber per miles of route" issue, not an attenuation issue) and just because you can theoretically get halfway around the world in 100-125 ms, doesn't mean that real cable routes will let you do that. India and New York are just far apart, and you've got to deal with it, unless you want to drill a hole through the earth's core.

    Second, aside from what the _standards_ say, calls don't become "functionally useless" above 150ms - just a bit slower, and if they're much slower you might not want to use that cheap speakerphone. Back in the old days, when we used to walk 20 miles barefoot to the schoolhouse uphill both ways, satellite was the standard way to talk across oceans and sometimes even within the same continent, and they were ok. Not great, and sometimes annoying, but ok.

    Direct-dialed calls from California to Tennessee almost certainly *are* carried on POTS, though calling-card calls to India usually aren't. POTS isn't just analog-on-copper - the call gets digitized to 64kbps PCM at your first telco office, switched through circuit-switches, and carried on T1 lines (1.5 Mbps synchronous channelized stuff). The T1s get muxed together onto fiber, of course, and the fiber's usually DWDM stuff that puts 16-64 2.5-10Gbps channels on each pair, but with the major US telco carriers, most of the calls are still old-school as far as switching goes. LA to Nashville is about 2000 road-miles, so if you get a good fiber route it should be about 20ms one-way.

    That'll be changing a lot within the next 5 years - the old phone switches are becoming obsolete, and soft-switch technology is getting a lot cheaper, and it'll be the costs of switches (including parts and labor) that drives a lot of the change - fiber bandwidth is so cheap that it's cheaper to haul intra-US calls uncompressed compared to deploying telco quantities of compression equipment. Another big driver is mobile phones, since they already use a compressed-voice infrastructure.

    International's a lot different - bandwidth across oceans is expensive, so it's worth paying to compress the voice, especially if you either don't use IP or use trunked compression protocols that don't need to waste 40 bytes of IP/UDP/RTP header on a 10-byte voice sample. Those 1 cent calls to Asia are doing a lot of that.
