I am just testing 2-way SMS and would like to implement and test, one-SMS 2 many-SMS feature
in 2-way SMS mode.

I am not testing web-based GUI interface as don't want to let a third party to flood service users with SMS messages.

First option.
Registration of users via SMS

Second option.
Sending the same message to a group of registered users (SMS not web interface)

Third option.
System administration via SMS sent from phone number registered as an administrator

Fourth option.
Multiplicity of usb modems connected and installed

Last question.
Please let me know if you aware of any commercial application of such sms application,
as a number of sms send software comes free for Linux.

What is a price of unlocked, not-limited nowsms application for tests ?

Hi Jack,

We're actually working on a 2-way application that does some of this. The only problem is, I don't know when it will be ready.

Here are a few comments.

You'd basically implement a 2-way command that processes all received messages. You could setup different commands to process different keywords, but personally I think it is easier to do the keyword parsing logic in your own application.

The simplest behaviour for a 2-way command is for it to echo back a response that is sent back to the message originator.

In some cases (registration) you might want to use this type of logic. But in other cases (forward the received message out to multiple registered users), you need more complicated logic.

I would recommend not using the "echo" (a.k.a., "Command returns response text") solution.

Instead, whenever your script wants to send a message, it should initiate a new request to NowSMS to send a message. This request is sent from your application to NowSMS over the HTTP/web interface. So even though you're not using the web interface for end users, you would want to allow your application to post to NowSMS via the web interface (and you can restrict IP addresses so that only the IP of your application is allowed).

Here's a link that's good for explaining how to get started with 2-way SMS:

For generating new HTTP requests to send a message from within your script, see the APIs section at the bottom of the following page, where there are links to Java, PHP and command line interfaces:

Multiple modems can be added and used by NowSMS simultaneously.

I only deal with technical issues here on the discussion forum. For pricing/sales information, give us a call, send an e-mail, or fill out the web form at

Dear Des,

thank you very much for your excellent product
and your kind reply.
I started to test NowSMS 4 years ago, unfortunately price per one SMS was then high, to test such service in open.
Today I go back to NowSMS with nicer tariff plan from another telecom operator.

What I mean is a feature to let append more script code into Echo field.

It goes better with flow-chart to explain the issue.

1 SMS send to NowSMS Gateway
response generated
1 response send to sender
2 response send to another phone number.

So one SMS send in 2-way mode, generating
2 SMS messages to be dispatched by NowSMS.

You are right.
Web server should be run locally, without remote
Internet access, to not let intruders to flood network with tons of SMS messages.

So I have to look for web interface-based solution.

I have asked you about general price quotation
as I plan to set-up NowSMS Gateway in local school community for tests
and making time-limited service for high school students is exactly like making time-limited
offer by MS with Windows 7.

When application gets on popularity, time comes for its termination.

In the meantime I have tested SMS application by Huawei, made of widgets.
So each submenu command invokes new widget as local application.
