On what factors do the sending/receiving rates of sms' depend? Modem? Phone carrier? Anything else? What is the rate at which NowSms can send and receive sms' per minute? Any particular modems/carriers you suggest to optimize these rates of sending/receiving? My service will be receiving and sending a lot of traffic. THANKS for any help! | |||

Hi Zola, The trial version of NowSMS is limited to a max throughput of 30 messages per minute. Licensed versions range from 5 messages per minute to several hundred messages per second. Overall throughput really depends on your SMS connectivity. If you're using a modem, then on average, you'll only see a max throughput of 6 to 10 messages per minute, per modem. (Overall throughput dependent on signal strength and mobile operator performance.) We have tested modem configurations where a modem supports SMS over GPRS/EDGE, and you can get closer to 1 message per second. However, our experience has been that few mobile operators have this support enabled on their network (and some operators that had it enabled at one time, have since disabled it), presumably because they don't want modems submitting messages at such high throughput. (3G vs. 2G makes a big difference performance wise for sending MMS with modems, but not for SMS.) What country/region are you located in? Availability of different modems tends to vary quite a bit by region. -bn | |||

Thanks for the reply. 1. I couldn't find a link to buy the product, where is that? 2. When you say 6 to 10 messages per minute per modem, is that including sending AND receiving SMS's? 3. I'm in the US. Do you know of any operators that offer SMS over GPRS/EDGE or the operators that provide the fastest sending/receiving rates? Thanks for your help. | |||

Hi Zola, Sorry to take so long to post a follow-up. We don't process orders on-line. Your best bet is to give us a call or drop us an e-mail (details at http://www.nowsms.com/contact.htm). Sending and receiving are metered separately ... so receiving doesn't count against your sending quota. (However, when you are using a modem, receiving a message can cause the modem to abort an active sending attempt, which can impact your performance.) In principal, NowSMS receives messages as fast as it can, to avoid situations where messages might be dropped. We do meter the rate at which received messages are passed to the 2-way callbacks ... but we don't let them backup on the network. In the US, the Multitech GPRS modem is a pretty good choice. Note that you're usually better off with the GPRS model (Wavecom chipset) than the EDGE model (Siemens chipset) ... even though EDGE is theoretically faster. (Similar to comments above about 3G ... higher packet data speeds only offer a boost when you're talking about larger data packets being transferred, like with MMS.) In the US, we've tested SMS over GPRS with T-Mobile, where it has worked ... but unfortunately, when it has been available ... it has been only available regionally. A couple of years ago, we noticed that it was not available in New York, but it was in Baltimore. Later tests suggested that it was no longer available in Baltimore, but was available when we ran some tests in Jacksonville, FL. If you're interested in SMS over GPRS support, the best thing to do is to try with the trial version, which will go up to 30 messages per minute. Under "Properties" of the modem in the "SMSC" list of NowSMS, configure "SMS Access" as "GPRS", and see what type of speed you get. (If you don't see the speed increase, that usually means that the modem could not find this support available, and it dropped back to circuit-switched mode. Or in some cases the fallback doesn't work, and the messages cannot be sent when this option is configured.) -bn | |||

Bryce, thanks for the reply. A few more follow-up questions: 1. You said that receiving a message can interfere with the reception of a message. Is this is a wireless service problem, or a porblem with NowSMS, or the modem. I would need to prevent this from happening as my service has customers that will be paying to receive their messages timely. 2. So if I'm just doing SMS, I should buy a Wavecome Multitech GPRS Modem? (Just confirming) 3. Just to clarify, if I were to get service through T-mobile and buy a modem, is their a flat fee for NowSMS? I don't intend to have this gateway on the internet and I'm looking to avoid charges PER sms b/c of the high volume I'll be sending. Thanks for your help, again. | |||

Hi Zola, 1. It's a wireless service issue. The message being sent just has to get retried. 2. For the US, yes, that's what we'd recommend. And if you're talking SMS only, the GPRS model is slightly more reliable than the EDGE model. 3. For NowSMS, yes. I can't speak for mobile operator service plans, but when sending with NowSMS via a modem, to the operator this appears the same as sending an SMS from a mobile phone. -- Des NowSMS Support | |||

Thanks for your all your help. My final two questions: 1. Back to #1: Is NowSMS configured to automatically resend the message ("retry it") if it is interrupted by a received message? In other words, would I have to manually configure it to try to resend a message if its interrupted or will NowSMS take care of this problem? 2. Do you know anything about Short Codes? Is this something I take up with my wireless carrier? THANKS | |||

Hi Zola, 1. It all happens automatically. If a retry is required, the first retry is quick. If a second retry is required, there is more of a delay, in case there is a problem with the message, giving other messages a chance to be attempted. Retry settings can be tuned, but usually there's not a need to unless there is something unusual about your environment. 2. You can go through an operator, but usually you go through an aggregator (a.k.a., SMS service provider), because you want a short code that works across operators. (In most major markets, if you try to go to an operator, they're going to direct you to an aggregator, because they prefer to do their business that way.) There's generally a recurring fee associated with this. Pricing models vary ... usually there's a setup fee to make sure that you're serious, and then you've got monthly minimum commitments, usually with a few months pre-paid. For the US, you can learn more at http://www.usshortcodes.com, which is the web site for the cross-operator short code administrator. You'll see there that they charge you $1000/month to lease a specific short code (or $500/month if you ask them to assign you one randomly). You need to commit to at least 3 months. But if you go directly to the CSCA there, you then have to negotiate with all of the operators to get them to activate it and get them to route it. Most people just go to an aggregator and work all these details through them. But I figured it was useful to point out this underlying administrator, because you can see that there's a fixed cost just for having the short code, before you get into any messaging charges. From US customers, we probably see mBlox used more than any other aggregator when it comes to people using short codes. But that is probably because NowSMS has support for some special parameters required by mBlox. Other providers that come to mind include Sybase 365, Verisign, MX Telecom and OpenMarket. You'll usually connect with one of these providers using SMPP. -- Des NowSMS Support | |||

What's the difference between an Aggregator and an Operator? Do I assign the Short Code to my TMobile account?? And how do I find out more about NowSMS pricing? Thanks | |||
| Des - NowSMS Support Board Administrator Username: Desosms Post Number: 402 Registered: 08-2008 |
Let me start with this.
No, it is not possible to use a short code with a modem. You would connect with a service provider over the internet for sending/receiving messages. Usually you would use the SMPP protocol.
A mobile operator is someone like AT&T or T-Mobile. An SMS aggregator is a service provider that manages connections to multiple mobile operators (and other aggregators). When you move out of the modem world, you are talking about different types of messaging accounts.
