Raspberry pi send sms without internet

These messages would be sent to my mobile phone and alert me about specific events recorded by my Pi. In previous years there were services that allowed you to send free text messages via the Internet.

In general these services were either illegal or relied on loopholes in mobile phone networks that have since been fixed. I decided to use TxtLocal as they provided a low cost solution with the added bonus of example Python code to send messages from within a script. This was perfect for my Raspberry Pi project.

It was quick and easy to sign up for a free account. This allows the script to run but without using up your credits. Make sure you enter your own user name, hash and target mobile phone number. This will send a real message to your phone and deduct 1 credit from your TxtLocal account. How expensive this facility becomes is really down to how many messages you get your Pi to send. For my purposes I only intend on sending a few hundred per year.

However I found what I think might be a better solution. A guy named Ehsan Foroughi created a python library to interface with google voice, and I modified it to send sms messages. And it works great on the Pi out of the Box. To Matt, google voice basically gives you a free new number. To do SMS all I need is a python script much like yours. It may be more viable in other countries. Ireland I wish that I had this code back in April this year for my 2nd year Mechatronics project at Uni!

Thanks for this — just signed up via your link and it worked beautifully immediately :o Nice one! Could be worth a shot, that way you will not have to send the texts to your phone via an external site, but can send straight from the USB device and out. Nice post… Seems to be exactly what i want. I registered and used the script above changing the neccessary things.

I was wondering what could be wrong.

Send SMS Using Your Raspberry PI and a 3G USB Modem

Please help Ashok. I did the necessary changes. When I run the scripti get the below output but no sms. Any Suggestions. It says the sms is being sent but no sms is received. Im sending the msg to an Indian number. Plus is it necessary that i run this code on pi?

Please reply. Check the online dashboard to see if there is any record of the service receiving your request to send. Website info must be out of date and yes I set it to 0. Download the script again and give it a try.

As long as you put in valid username, apihash and numbers it should be fine now. The international dialling code for the US is 1.There have been a couple of problems, but they were fixed very quickly, not at my cost and in a very friendly manner. Hi ModMyPi! I wrote some intro posts on Building a Pi on Inventability btw.

There are many reasons why you would use multiple carriers, signal coverage in your area being one of them. That done, turn off your Raspberry Pi and plug-in your dongle then restart your Raspberry Pi and ssh in to it. Do this with the lsusb command. Run the following command:. So you discovered that your new 3G dongle thinks it is a normal USB drive and not a 3G modem, we just need to install a few packages and are just a couple of files and we will be all set.

When your Raspberry Pi has finished rebooting, run the lsusb command again and if you look something like this you are golden:. It will almost certainly be different from the one you see above but will take the same form, the ID number of the device above the one you will need to remember is: 12d You will almost certainly be using the name ttyUSB0 in the upcoming commands. Remember before when I said you need to keep track of those eight numbers, well this is where you will need them.

You need to create a new config file with the following command note the file name is the same 8 digits :. The file should have the following contents, obviously adjusted to use your devices ID numbers.

That should be the only thing you would need to change. This software is called Gammu and we install it like this:. A menu will appear. Use the arrow keys and the return key to navigate. Now use the arrow keys to navigate down to Make Sure You Save by using the arrow keys to highlight the save option and then pressing the tab key and selecting the ok option.

We check everything is groovy with the following command:. Finally, time for some computer-based SMS shenanigans! Use the following command to see if everything is working. If all goes well, after a few seconds you will receive a text message to your mobile phone with the word test. In a follow-up post I will show you how to get your Raspberry Pi to do things when it receives SMS messages containing particular words or phrases, so look out for that.

If you wanted to, you can activate them without registering them to your home address. Run the following command: lsusb. Huawei E 3.The SMS will be able to send via the form on the website. The software to communicate with the modem I will write in C.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Install the apache2 package by typing the following command in to the Terminal: sudo apt-get update sudo apt-get install apache2 Then we install PHP. For this purpose, we will use the minicom program.

If everything is fine the answer from the modem will be "OK". My website. By adachsoft geek. More by the author:. Add Teacher Note. Before using these scripts, you need to configure your connection to the database server. I use an external database on my server, but you can also use a local database on the Raspberry PI. It contains a form to send SMSsent form is saved in the table "sms".

The SMS software was written in C. To be able to execute EXE on linux, you must have mono installed. At the beginning of you need to configure the connection to the database and set the serial port under which you have a USB modem. After compilation, we create "SMS-cron" folder in home directory and copy files there: Mono.

In one of my projects I will leave the Raspberry Pi working in a distant rural area with no wired or wifi connection. The only possibility to connect to it is through the cell phone network.

You can obtain many Raspberry Pi accessories including 3g modem from banggood. In order to connect the Pi with the cell network we would first need a 3g modem. Fortunately nowadays they are very cheap and easy to get hold of. The carriers even give them for free. This is very convenient for Windows users because when you plug the modem it opens as a usb stick where all the necessary drivers are, you install them and then it is automatically switched to a modem mode.

Of course it is not that easy under Linux. The good news is that there are plenty of articles how to do it and it is not that hard, so I will not talk about it here :. A good reference are these pages:. But what are AT commands? In reality it is not so straightforward to get a list of those commands since for 3g dongles there is no official documentation at least for those I have.

After that you should see an empty screen. Now what you type is directly send to the modem. You should see OK in response:. AT OK. Now we are ready to send a short message.

There are two ways to do it — either in text mode either in PDU mode. For now we will stick to text mode because it is easier to work with. The phone number can be the full one with the country code or the short one starting with zero. How do we do it in python? In text mode the command syntax is the following:. It would be much better if the modem notifies us pushes directly once there is a message. If we receive too many messages the memory eventually will fill up, so how do we free space?

For more information regarding the ZTE at commands look for the fucking manual on the internet :.Nonetheless, there are certain situations in which this technology acts as the go-to choice. The Short Message Service or SMS as it is known, is one of the most robust technologies in the area of mobile communications.

The service has many limitations including restrictions on the length of transmitted messages and asynchronous processing. In spite of such limitations, or rather precisely because of them, SMS continues to be bread and butterfor providers. There is good reason for this since the technology does not rely on the Internet, a channel of communication which is becoming ever more vulnerable.

With respect to the Raspberry Pi, there are a number of different areas of application which utilize SMS. For example, it is usually still possible to register a measurement module via SMS on a 2G network and send status updates even when there is no UMTS reception.

Also, the mini-PC can warn of outages on the network. Likewise, the receipt of an SMS can be used to trigger a specific action. In another scenario, SMS constitutes an independent channel for a so-called two factor authentification. For this process, the Raspberry Pi uses SMS to send a one-time valid password to a previously provided telephone number. The one time password can then be used together with the user name and a regular password for more secure login on sites containing sensitive information.

Unfortunately, you often have to use SMS in order to check your available balance and data volume usage. The Pi can assume this task for you so you don't have take the card out of the stick and insert it into a mobile phone. Below, we provide a brief description of how to install the hardware. In addition, Gammu can be configured as a fully functioning SMS server without much effort. Users then have complete flexibility when it comes to the processing of ingoing and outgoing messages.

A first generation Pi requires a powered USB hub. You will need two software packages Listing 1 and 2 to operate the hardware. Once these packages are installed, the system should automatically recognize the UMTS stick when inserted.

Sending SMS Text Messages Using Python

The exact number of corresponding files depends on the type of UMTS stick you are using. Typically, you will see three. If none of the files in question exist, your stick may not be supported. However it is more likely that the Raspbian system is having problems. Try re-inserting the stick.

If that does not work, your next step should be to run the command sudo udevadm trigger from the console. There is a good chance that the system will automatically recognize the UMTS stick unless you are using a very new model.

You also don't need to go through all kinds of gyrations during installation in order to actually be able to send and receive SMS messages. The command from the third line in Listing 1 takes care of this. You only need the Python package if you want to access the SMS functions. The documentation process has its own package named gammu-doc.

Sending SMS on a Raspberry Pi

However, there are a number other packages that accompany gammu-doc. Therefore it is a good idea to save yourself the space. At first glance, Gammu [2] appears slightly antiquated. The software dates back to when the first intelligent mobile phones from Nokia and other makers first came out. As a result, the name "Nokia" still appears in 50 places in the Manpages.

However first impressions can be deceptive.Logout Register. What do I need to enable SMS sending functionality a device? Thanks for any help, kapauldo.

I suggest reading the portion of Heinlein's The Moon is a Harsh Mistress where the protagonist describes the problems of "bootlegging" telephone service. Re: how to send SMS messages without internet Wed Sep 17, am my only goal is zero configuration, i don't mind paying for a service or whatever, or use a sim card, my only point of saying "without internet" is that there will be no human available to configure wifi, if i can connect to a cell network or SMS I don't know if SMS is the same thing as a cell networkthose are both fine.

Re: how to send SMS messages without internet Wed Sep 17, am Do you know how to send a sms for free worldwide? Note that sending a SMS every hour can get kind of expensive. Check your service plan, also note that some plans with large SMS bundles may have prohibitions against automated use, if you are doing a hobby project you'll probablly get away with it but if you are commercialising then violating your service contract is probablly a bad idea You may want to investigate if there are any providers in your area who speclise in service plans for embedded uses.

The prohibition against automated use is set in place to protect the carrier from a flood of messages suddenly coming from a single node. When configuring this thing, make sure you have a way of testing it thoroughly before even connecting it to a phone network.

If it does indeed only send a text every hour it shouldn't be a problem i. A very good failsafe is also to use a prepaid card, to protect yourself from surging costs should something go wrong I had a friend who did this a couple of years ago and told me it was a fairly simple procedure.

On PCs, screen mirroring works on Windows 8. If you opted for Roku instead of a Google Chromecast, you can still cast YouTube videos from your mobile screen to your TV. You'll see a string of numbers to enter. Go to your mobile device, open a browser window and go to youtube. Now when you're in the YouTube app on the mobile device you paired, you can send the video to your TV screen by clicking the cast iconprovided both devices are on the same Wi-Fi network.

The five simple actions here can all be done in a matter of minutes. When you break them down to their most basic ideas, it comes down to removing psychological barriers and offering better reasons to sign up. Without it, the page has no purpose. And yet so many sites make the call to action nearly invisible. Make sure that your call to action is differentiated from the rest of your page. Use contrasting colors, a larger font, and prominent positioning for the best results.

Test your call to action, too. Some phrasing might work better than others, and one button color might work better than another. The only way to know this for sure is to test the possible combinations. The goal is to get someone to sign up, right. So make it as easy and as simple as possible for them to do so. The best signup forms include no more than the absolute bare-minimum required information.

If money is involved, then make sure you only ask for the minimum amount of information required by your credit card processor. If you need a shipping address, make sure they can auto-fill that information from their billing address. The key here is to lower the barrier to entry as much as possible. Every additional field is an opportunity to change their mind.

Guarantees are going to vary based on what your visitors are signing up for. If money is involved, make sure you offer some kind of satisfaction guarantee. But the problem there is that people are more likely to make a split-second decision to cancel.

Psychologically, going to a separate signup page is a barrier. The modal window also has the benefit of decreasing distractions on the signup page, as it shades out all content other than the form itself. This reduces the risk that your visitor will become distracted by another link or something else on the page and abandon your signup form before completing it. Why not include a free ebook or whitepaper for subscribers. Or a phone or email consultation.
