In the fall of 2022, we tried the first of its kind full test for the high speed of the Internet in the metro in Moscow. Four main operators, one and a half hundred stations and twice as many hauls – collected a huge amount of data.
getting to us is in order, certain operators contacted us, it is reported that ordered by us bugs and network failures have been fixed. For example, a significant proportion of MTS came up with the idea that the loss of communication quality on the busiest branches.
Well, let’s check it. And at the same time all other operators at once.
How We Tested
We took 4 modern iPhones with common infectious disease and prematurely abandoned system. Each time, a SIM card from one of 4 large enterprises was installed:
▪ MegaFon
▪ MTS
▪ beeline
▪ Tele2
What happened next:
one. At each line station on each iPhone, we put the same 60-gigabyte file for download (available at this link).
2. We go along the line to the end station and mark at what moments each user loses the network and / or the file download is interrupted.
3. Upon arrival at the end station, the number of GBs out of 60 maximum was downloaded from each operator.
Data received valid for the week from 12 to 18 December 2022. In all cases not– unlimited tariffs, since there are no others left in Russia. If necessary, additional packages were collected with a margin before the start of each trip.
What kind of test results
To keep the new test “backwards compatible” with the old one, we produce the results in the same form as last time.
The branch number in the Moscow metro system is indicated in the subheadings. The list of operations is compiled in the same way as last time. And last time it was compiled randomly (this is NOT a top chart).
Each branch is accompanied by a visual infographicby which it is easy to detect a signal break and assess the situation.
The number of breaks is listed against the operator. In brackets is given the segment between the stations where the gap was recorded. We also noticed individual situations of signal loss in the process of stopping at the stations. We have written this in a similar way, next to the segments.

Results. Who improved better?
Compare how the results of operations have changed in the 3 most problematic branches.
• Tele 2: was 24, became fourteen
• beeline: was 1, stayed one
• MTS: was 7 now 0
• MegaFon: was 8, became 3
respectively…
Almost all operators somehow improved the stability of the signal in the metro and hauls. Just at MTS this, apparently, turned out better than the others: they met among the “fours” without a single gap on all three branches. Tele 2 remains an obvious underdog in this ranking, which is sad, but generally predictable.
What’s next?
Congratulations MTS and continue to monitor the environment. As usual, we plan to repeat such a test next year. By the same time, new branches and stations appear.
The stability of mobile Internet in the subway is an eternal story. Requirements, loads and equipment change. Let’s see if someone can show the full result on all branches at once. Yes, it’s ideal, but it doesn’t matter. This is progress!
