The connection is excellent. A great smartphone app.
Perhaps, what upset me a little is that the transition to a different tariff is not instantaneous, but from zero hours the next day,
while the phone settings are needed for the Internet. Which is completely unusual and not obvious.
As a result, we were left without Internet for almost a day, because at first we waited 24 hours to switch the tariff, and then until 9 a.m., until the communication salon opens, to understand why there is still no Internet.
