ENG: Why do my smartphone spends my money?

Why do my smartphone spends my money?

You have just purchase a new smartphone, turn it on, do a little typing on it, look for the current time and temperature (although you can easy exit to the balcony and see what kind of weather it is :-) and just when you thought to call your best friend / girlfriend, smartphone tells you that you have no money on your account.
Or another scenario: you bought a new smartphone, do a little typing on it, you did not "go to the internet", you left it on the side and a few hours later when you want to make a call or send a message, money has "mysteriously" disappeared from the account (assuming that you do not have a subscription).

First of all, I have to say that this article is written with non-technical language in order to be as simple as possible for people who are not technically qualified and have little experience with technical expressions.

What happened? The key term is "DATA TRAFFIC" or "CELLULAR DATA" (depending on the manufacturer of smartphone and the software version, this term can be called differently). The first thing you must know is that the operator which device you bought aim to earn as much as he can from you. They don't want for you to be happy and laughing all the time as suggested by their numerous stereotypical adverts, their goal is to get as many of your money as they can. One of the "little things" that helps them is automatically switched ON data traffic in the new smartphone.
Basically, all smartphones devices have a "desire" to be connected to the Internet all the time, whether they want to upgrade themselves to the latest version of software, either to contact the manufacturer or doing lots of other little things.
Most of the programs that are installed on the device also want to go "...little bit to the Internet", one wish to upgrade itself, the other wants to connect somewhere, third wants to retrieve the latest data from the net...
It should be noted that most of these programs do not notify user when they will connect to the net, they run invisibly in the background. A classic example is widgets for weather on the screen for real-time display of temperature, humidity, wind and so on. This program does not miracly finds it's data, but it connect to the net, to his server from which retrieves data. There's masses of similar programs that operate on a similar principle. If you play some games they can also be invisibly in the background connected to the Internet. From applications that have visible connection to the Internet, we can mention for example, YouTube or web browser.
And that's okay, because if you have a smartphone only for calls and SMS, instead of that you can use old Siemens C35 or something like that.
For all of that you need to have a card with included (paid) data traffic. Some standard should be 1GB or more of monthly data traffic. Once you have purchased data traffic and turn ON data traffic in smartphone settings, then your smartphone will connect to the Internet through it and MB (megabytes) of data transferred is much cheaper than through GSM signal.
Now we are back to the beginning with the question of why my phone spends my money without my notice?
First you should know did you have included some kind of data traffic in your mobile package. If you do not have any data traffic, then your smartphone will connect to the Internet via a GSM signal which is much more expensive than via data traffic. In this case, I recommend that your first thing to do with the phone after you unpack it, is to turn off the connection to the Internet (turn off data traffic) until you buy some of the data plans offered by your operator whose SIM card you have.
If you have a data plan, but your smartphone "too soon" spend money, then you need to think about what you are doing with smartphone, perhaps you little too much "hang" on it. Also make sure what applications you have installed on it, and what each application does. I have already mentioned various weather programs, they will be lot of time connected to the Internet, so let's say you have something that is constantly receiving the latest news, ads, betting news and a bunch of other programs, each of them takes its share of the pie.
If you are at home and you have a "classic" ADSL over the wire, I certainly recommend that you turn ON the wireless network in router and connect smartphone to it and then connect to the Internet using a wireless network. Mobile phone is first connected to a wireless network and over it goes to the Internet, and if there is no wireless network then you will be connected via a signal from a smartphone. Of course, this is only possible within the house with full extent of the signal from the router.
I recommend a good program that can track the amount of MB that you are using:
RADIOOPT http://www.radioopt.com/
The program, besides the control of traffic, has the option of turn OFF data traffic when you cross a certain level of data traffic which you defined, depending on the amount of paid traffic in the data rate.
For example, if you have 1GB of traffic, set off at 950MB.
How to turn off/on data traffic (in simple terms, the ability to connect mobile phones to the Internet)?

This is not easy to say because it depends on the phone model as well as the version of the software in it.

For iPhone IOS v 6.x: Settings - General - Mobile Data - ON ili OFF.
Good iPhone manuals:

Samsung S3 calls that "Use packet data". Start Applications - Settings - More - Mobile Networks - Use packed data.
Easy way is to use Google: "how to disable cellular data on *your smartphone model*".
For prices and options for data traffic look at web site of your GSM provider.
