People who use the communication services of cellular companies often forget about the conditions under which their number is serviced. Getting used to regular calls to specific destinations and corresponding charges, subscribers have to work hard to find out how much a particular service will cost. For example, calling to another country, etc.
In order to avoid falling into such situations, it is enough to find out what prices for the selected tariff plan are used on the SIM card. How to find out tariff plan to Velcom and clarify the terms of service? Is it possible to do this yourself or do you need to contact dispatch service specialists? All these issues will be discussed in the article.
How to find out the tariff plan for Velcom: possible options
A subscriber can obtain data regarding his number in several ways. Conventionally, they can be divided into two categories: through self-service systems or with the help of the operator’s service employees mentioned earlier.
Obtaining any data related to the account status, list of connected services and options is free of charge. Let's take a closer look at each of the methods that can be used to view information about Velcom tariffs ( corporate rate, options for individuals).
Using an automated service to manage your number
The service operator "Velcom" has developed an entire service that is intended for subscribers of this company and allows for complete control of the number: change tariffs, activate and deactivate services, view expense data and receive other information. For people who use communication services and are already familiar with this service, the question of how to find out the tariff for Velcom is not relevant, because all the information is at hand. You can receive it in any convenient way: through a USSD service, by calling a short number, or via the Internet.
How to find out the tariff plan for Velcom through the web interface?
If you want to have full access to your number, view it and at any time independently manage services, account and change Velcom tariffs (“Everyone Talks”, “Smart”, etc.), then we recommend using the web interface. By going to the cellular company’s website and clicking on the “personal account” link, you can find yourself on the home page.
Here, before gaining access, you will need to register. This is not difficult to do; you should carefully read the instructions located on this form. This procedure is carried out only once. In the future, the subscriber will be able to open his personal page at any time, using the assigned password. As mentioned earlier, having the opportunity to view data by number, a person who is a client of Velcom will be able to perform any actions “by click”.
Voice information system

By dialing the combination 411 (+ dial key) from your number, you can get to the multifunctional service. It is enough to select the appropriate items to obtain the necessary data. Please note that here you can also perform any operations with the number. In addition, you can always press the button to connect with an operator if some actions cause difficulties and you need to clarify some nuances.
Short (USSD) request service
If you are interested in Velcom, use the SMS notification method. You can send a USSD request from the SIM card for which you want to receive data as follows: *141*2*1# + dial key.
In response to such a question, the operator will send a text notification to the client’s number containing the name of the tariff. By the way, this request It is also perfect for those subscribers who do not understand their number and would like to refresh their memory. After all, the message sent by the automatic service in response to the previously given combination also contains a telephone number.
View fare information
After the client finds out what tariff he uses on his number, he can easily clarify what conditions apply to him. In particular, we are talking about the cost of communication services, the amount subscription fee(if available), the number of packages that can be included in monthly or daily payments. It is more convenient to do this through the official resource of the operator; it can be easily found through search engine. Next, you need to find the desired name in the “Tariffs” section of the Velcom website (Smart, for example) and read the conditions:
- You must pay 14.50 rubles monthly for using the tariff plan.

If you use the Mobile Internet service on a 3G network, you can receive and make calls without pausing your Internet session.

The data transfer speed in the 3G network depends on: - the distance of the subscriber from the base station, - the density of urban development,
- local interference,
- subscriber movement speed,
- base station load.
When working on the Internet, speed is also significantly affected by factors independent of network A1:
- capabilities and/or limitations of the server from which the data is downloaded;
- congestion of the Internet channel to the A1 network;
- number of streams organized for downloading;
- setting TCP/IP protocol parameters in operating system PC;
- location of the subscriber: indoors or outdoors.
In addition, the speed limit is imposed by the equipment used by the subscriber.

Now we have to find out what Velcom USSD requests exist. This mobile operator offers a lot of different commands that allow you to receive this or that information about the SIM card, as well as enable/disable certain functions. In general, USSD requests on Velcom are available in huge quantities. But we will consider only the most useful and popular of them. Maybe they will help you solve this or that problem more than once.
What it is
But first, let’s find out what our current needs are? Knowing this, you can understand whether you need them or not. Maybe you can do without them completely? USSD requests from Velcom, like any cellular operator, are nothing more than a means of subscriber self-service.
With their help, you can control your phone balance, check and change the tariff plan on your SIM card, perform various functions, as well as disable and activate certain services and options. The main advantage of such combinations is that they are free and can be activated at any time of the day or night. The main thing is to know what exactly you need.
Balance
Perhaps it’s worth starting with the main function - this is a USSD balance request and all the commands that will help you control the funds in your SIM card account. There are not so many of them, but there are some special ones among them.
For example, a balance request is made using the combination *100#. At the end of each dial, you need to click on the “Call” button. In response, you receive a message about the status of your SIM card account, and the result is displayed directly on the screen.
USSD requests from Velcom allow you to easily change the tariff payment system. To work without prepayment, you need to dial *145#. If you want to register some unconfirmed request, then *141*1# will help here. Basically that's all useful commands to manage your account. We continue to study Velcom USSD requests further.
Rates
It's no secret that using these commands, any subscriber can change their tariff plan. Each offer has its own combination. To know full information You can find out more about this on the operator’s official website. After all, Velcom has many tariffs. It would take a very long time to list all the USSD commands for connecting them. So this moment check with the operator.
Instead, we will try to learn universal USSD requests from Velcom. The tariff plan that you are currently connected to can be found out using *141*2*1#. In addition, the subscriber can receive his phone number by dialing *147#. Information about the Internet tariff plan is displayed after dialing *141*2*3*1#. Everything is easy and simple. In some cases, you receive an SMS message with all the information you requested, but often the data is displayed directly on the phone display.
Additional services
Now a little about the interesting capabilities of our today's operator. Velcom also has its own USSD requests for them. “Favorite number”, for example, is added using *141*3*3#. After this, you can add this or that subscriber to the appropriate list.
Additionally, note that you can also enable some interesting and useful features using our commands today. For example, you can connect the Internet, MMS, and security to your phone with one single request. With its help, you will also receive all the information about the mobile Internet that is available on the SIM card. To do this, dial *135# on your mobile phone and send a request for processing.
Sometimes you want to talk while roaming. Velcom USSD requests allow all subscribers to quickly connect to similar services. "Roaming" (international) is activated using *141*3*2*1#, and " International calls" can be activated by dialing the combination *141*3*1*1#. It turns out that without outside interference at any time, everyone is able to activate the services of profitable calls by mobile phone Abroad.
Services
Do not forget that Velcom USSD requests have one more feature. And it applies not only to this operator, but to everyone in general. These commands make it possible to enable/disable certain additional service packages and services. What can help us when communicating?
Let's say, the "500 SMS" option package. To do this, you must type *119# from your phone. Please note that the request itself is free. But to connect this or that option you will have to pay according to the tariff. All available settings (Internet and MMS are included here) are received after sending *135*0#, and “Mobile Internet” is activated by the command *135*1#. As you can see, there is nothing difficult about this.
It is also worth paying attention to somewhat non-standard services. Velcom offers its clients a service. Oddly enough, it connects without problems using the USSD request *200*2#. "Melofon" is another service that subscribers often pay attention to. And it is activated through the combination *424#. In principle, these are all quite popular services that you can connect to.
Help and queries
The last point we will consider is sending “homeless people”, as well as receiving reference information on a SIM card. Velcom allows you to do all this using certain USSD commands.
So, for example, anyone can request a call back (send a “homeless person”) for free. Dial *131*friend's number# and send the command for processing. Another Velcom subscriber will receive a free message from you asking you to call back. Sometimes this function very useful.
The balance of free SMS, MMS, minutes and Internet traffic also has to be checked from time to time. In this situation, another self-service command will help. It looks like *100*1#. If you want to know the whole list paid services, connected to mobile number, contact *141*2*2#.
Do not forget that the full list of USSD commands from Velcom is quite diverse. Sometimes you want to quickly look through it and select the desired function self-service. Anyone can do this very easily and simply. What does that require? Just submit a special request for processing. It looks like *141*9*1#. In response, you will receive an SMS message in which all available commands will be published. Unless this does not include requests to change the tariff plan (for a specific offer).
As you can see, Velcom USSD commands are varied. And with their help you can fully control the functionality of the SIM card. Don't be afraid to experiment. Remember that when you connect to a particular service, you will be charged a fee in the amount established by the tariff. All reference information is free.
