It seems that the home phone has long ceased to be a means of communication of prime necessity. The world is developing rapidly and does not stand still, even grandmothers buy mobile phones to always be in touch. Moreover, as practice and bills received show, it is much cheaper to communicate on a mobile phone with a certain tariff or on the Internet than on a landline phone.
However, for many, the question remains of what MGTS Moscow tariffs for a home phone for 2017 will be. Because, not many have completely abandoned their home phone. Even if calls are not made on this device, there is a subscription fee. So, it will definitely not work to free yourself from payments completely.
On the increase in payment rates
As you know, our country has been experiencing a rather difficult economic situation for several years now. This means that the actual wages of people are falling, but the payment for various kinds of housing and communal services is growing. Including last year, the Federal Tariff Service MGTS increased them from June 1, 2016. Tariffs increased by an average of 3.5%, although initially it was predicted that the increase would be 3.1%.
Of course, on the one hand, such an increase in tariffs is quite natural and minimal. Its necessity is associated with the level of inflation, which does not stand still. On the other hand, for some people, especially state employees and those who are already on a well-deserved pension, every penny counts. Therefore, even for a minimal increase in tariffs, people are preparing seriously and are extremely upset by such information.
More about the rise in price
It is clear that there are their own schemes, which are quite difficult to understand the first time. Because, not all tariffs are raised, and some directions in terms of payment level remain completely unchanged. For example, the price of MVNO packages with telephony does not change, and with the right approach, you can still save money on these services. Given that the number of services in the package will be increased by 42%. It is also worth noting that the tariffs of the "Advanced" and "Premium" packages will also not be affected by the change.
If we consider fixed telephony, which the state offers to the population, then you need to understand that the tariffs for it are made up of a subscription fee (it is mandatory to write off regardless of whether a person uses his city phone or not), as well as the cost of specific telephone connections. The tariffs of MGTS Moscow for a home telephone for 2017 to subscribers to individuals for using a subscriber line do not change. They are 205 rubles per month. But the switching scheme is selected individually.
Payment is charged every month for a subscriber connection and nothing depends on the tariff plan. The final cost of the connection will be combined and it consists of time payment plus subscription fee.
About popular rates
The most popular among MGTS subscribers is an unlimited tariff plan. For its fixed payment, as a result, you can get an unlimited amount of telephone connections. The payment for this tariff plan has been indexed by 3.1%, which in monetary terms is 12 rubles. That is, in a month now, according to this tariff plan, it will be 499 rubles.
The FTS also confirmed the indexation of payment for the basic volume of received local connections if a combined tariff is selected. In the second case, the cost of payment for services increased from 410 rubles to 429 rubles. But the basic volume of a conversation offered by this tariff, 400 minutes, has been completely preserved.
If we consider the cost of a minute of conversation for people who choose more than the previously accepted time-based cost of payment, then since the middle of last year it has amounted to 0.6 rubles. At the same time, earlier the cost of a minute of conversation in this case was 0.54 rubles. At the combined tariff, if 400 included minutes have already been used up during the month, the payment will not be about 52 rubles (as it was before 06/01/2016), but already 0.58 rubles. How much will electricity tariffs increase this year.
For connecting subscribers within the network, the tariff remains the same and the subscription fee is one ruble 58 kopecks for each minute used. The cost of local packages for telephone connections within the city has also not changed and is 625 rubles. This is true for the "Advanced" package, which has already been mentioned in this material. As part of this package, the volume of local connections does not limit, 100 minutes of calls are included in the price. But the “Premium” tariff costs 850 rubles (its cost has not changed either). This tariff will have 300 minutes for free calls.
It is also necessary to note the packages, which include not only minutes of conversation within the city network, but also calls to mobile phones. Here the tariffs have not changed and they range from 600 to 1850 rubles per month, depending on the conditions.
Important! The tariff for installing a telephone in a city apartment has also not changed since June 1, 2016 and still amounts to 1,800 rubles.
Home telephony today for many is still only a means for voice communication. But MGTS tries to keep up with the times and constantly introduces some new services. For example, if a landline telephone is already installed and subscribers want to connect additional company services, they can count on 10-40% discounts for the cost of each service separately.
Many MGTS subscribers who use the GPON optical network have already been able to appreciate innovations - fast telephony and digital television, high-speed Internet, modern cellular communications and even the ability to order security alarm services.
This is how the Tariffs of MGTS Moscow for a home phone for 2017 look like. As you can see, the increase was not for all tariffs, however, even where they were increased, they were quite insignificant. We hope that every person who uses the services of a landline telephone and pays for them adequately is satisfied with the quality of the services provided.
