I have a task to create production system for sending sms, for approximetly 10 000- 20 000 in a day. Our company have an agreement with local provider, and have multiple SIM card. I'm looking for 3g modems or some hardware (like GoIP) but i need very stable and quick solution.
What could you advise?
GoIP is cool, but isn't stable enough.
if you will use the chip to send msn try wit this service

There are many companies which provides sim card hosting services for receiving sms, I wanna how is this possible (at the core level)? do they use any kinda protocol or any custom devices for forwarding text messages to there servers.
This depends on the type of SIM card hosting being offered, if it is Virtual SIM card hosting (VSIM) such as this https://www.world-text.com/services/virtual-sim-hosting/ then this is only achievable were the provider has a direct connection to a mobile network over SS7. This requires very specialist knowledge, software and hardware, but is a very reliable and fast option.
If however they are offering GSM modem based SIM card hosting such as this http://world-text.com/services/sim-hosting/ then this utilises GSM modems which are normally hosted in a data centre and communicated with over IP, with messages returned to the providers SMSC. This method is slower, and is of course reliant on a local cell tower signal to work.
One of my customer is asking for setting up his own sms gateway, where his employees share sms freely. I suggested him to go with 1 of the bulk SMS API offered by other vendors. But he is willing to setup his own.
So when i went through different open source SMS gateways i found Kannel is best one. But it looks like we need to buy GSM SIM with some SMS package with GSM modem. By this every SMS sent will be chargable.
My questions is, how do way2sms, 160by2 works? I mean do they get charged by there vendor for free SMS sent by users? If no, Then how users are able to send free SMS?
Free sms is impossible with Kannel. Best way to deal with kannel is buying a sms-server service from a service provider. It will be very cheaper than normal connection fees.
USB Modem will give you problems when try to send bulk sms.
This is my newest project which consists of making a Server for phone and sms. I would like to do something like google talk where one would be able to make calls and receive calls or even text through the internet.
I would than be able to connect a land line phone or even just a microphone and call my cellular and talk. Otherwise just sending a sms message through the internet to my cell would be awesome as well.
Any Reference or guides would be much appreciated.
Notes:
Yes I know there are websites that do these things. Not what I am asking.
I got a Windows Server 2008 r2 setup at home.
I think I am a decent programmer, enough to be able to program this if I have some clue what I should be searching for.
Do not tell me it is impossible, as not too long ago I saw usb hardware that allowed to make calls over the internet (I know it's more complicated than that but I want to have this knowledge)
Okay, as others have already suggested, Asterisk is one the most obvious ways to go. Some time ago we created an online solution which allows most of the things that you have described, voip calling, dial plan generation, pbx, connection with landlines, sms sending, payments.
Tools used:
- LAMP (linux, apache, mysql, php)
- Asterisk
- OpenSer (http://en.wikipedia.org/wiki/OpenSER)
- 3rd party for SMS sending
- 3rd party for billing.
For phone you have two options:
not buying hardware and use voip. You can use some voip to land line gateways. There are many ways for achieving that. The most "professional" would be buying did number: http://www.voip-info.org/wiki/view/DID+Service+Providers. But there are other ways for example using skype api.
second option is connecting server to landline using special hardware - http://www.voip-info.org/wiki/view/FXO
Probably the funniest part would be writing webgui since writing PBX part could be little tricky. You should consider using Asterisk (free, Open Source) - Linux or 3CX (non-free) - Windows.
Regarding sms:
You can use sms gateway i.e.: http://www.clickatell.com/
You can buy gsm modem to your server
For the SMS part there is the SMSLib (http://smslib.org/), where you can use an attached phone to send and receive SMS.
You could provide a webinterface to write and read the SMS then of course, that would be the easier part.
For the calling I don't know, but it should be possible too. I know there are GSM chips for e.g. arduino but I guess it is very hard to reroute them to the application on the server. It could be possible with a short delay though.
Another option is to look into a VOIP library, e.g. Asterisk (http://www.asterisk.org).
I am stuck in the midst of a project. The project requires that a desktop pc must receive an sms sent from a mobile phone. How can I accomplish this? Please help.
You can connect a GSM Modem like this one to the serial port. It acts like a mobile phone with its own SIM card. I'm sure there are other products for USB.
On the software side, you can check for SMS messages by talking with AT commands to the device. I've done that in Perl and in .NET "manually", but maybe there are some out-of-the-box solutions.
i know (and have used) 2 ways to do this.
The quick, dirty and hacky way is to buy a mobile phone and connect it to your PC with a serial cable, then use old fashioned AT commands to control the phone (including listening for new SMS messages).
Many older Nokias support this, though it's not hugely well documented - this is about the best resource I found: http://wiki.forum.nokia.com/index.php/AT_Commands.
There are many exciting ways this can fail - you have to keep the phone charged, and in a data centre, reception is often pretty poor.
The alternative is to talk to a mobile aggregator (Google for likely candidates in your area). These are companies that can set up SMS short codes, and have APIs for forwarding the messages to you; APIs vary between the providers. This is usually fairly expensive - shortcodes cost money, sending and receiving SMS messages costs money, and the aggregator may not have deals with countries you care about. Caveat emptor, and all that.
You would also need a library to send/receive the AT commands to and from the modem.
See http://www.codeproject.com/KB/vb/phonesmsrecv.aspx
This software can help you. It uses a GSM/3G modem attached to a PC. It can store incoming SMS messages in a database, save to files, forward them to a webserver, in real-time.
(A 3g/gsm modem has a SIM card and therefore has its own phone number to which sms messages can be sent)
I'm taking shots in the dark here. I'd like to create a web service where eventually I send an SMS by using my own hardware. I'm not sure what I need in order to send an SMS myself. I don't want to use any of the existing SMS send services out there, I need to be able to send these SMS myself.
It looks like there's one opensource project in particular that deals with this, "Kannel":
http://www.kannel.org/
what I don't understand is, do I need to get a GSM modem to be able to send SMS? Do SMS gateways (like Kannel) eventually need to get to a GSM modem to send messages, or is there some other hardware you need to be able to actually send the messages?
Thanks
Just find an online SMS Gateway. These Gateway providers are your best bet since they have handled all the heavy lifting for you. Just utilize their API and you should be able to do whatever you want. Some of these gateways are free and some are not. I've included a short list below.

(Carrier based SMS transit)
http://en.wikipedia.org/wiki/List_of_carriers_providing_SMS_transit
I'm sure there are a ton more, but this will get you started.
You always need a GSM modem to send the SMS unless you use a provider that handles this for you (but they usually want money for this).
If you want to setup your own Hardware infrastructure, you have to get GSM Modem, A Sim card and use it to send SMS.
Other option, which I recommend, is to use SMS getways and use
SMPP protocol
XML or HTTP Apis
In later, you dont have to create any infrastructure and the starting cost will be very low compared to GSM Modem. You can get up and running in a day.
Note : to reduce the SMS costs, you should choose different getways for different countries. In India you can easily find getways who provides SMS at merely 3 paise
You will have to download an API that handles the sending and recieving of messages for you. I once used this in one project where i had my GSM Phone connected to my computer thru one of the COM ports. Configured the API to communicate thru the COM Port to listen to any incoming text messages also send messages thru my GSM Phone. Here is a great link to the resources i used for that project. I hope this will help. http://www.codeproject.com/KB/cs/SMS.aspx
