Slow Data Speeds

Hi, I just switched over from Sprint about a month ago. I’m currently experiencing terrible speeds in my home. I did reached out to T-Mobile and was provided with a signal booster. I get 3-4 solid bars and 9 on the coverage area and my speed is pretty bad. I have two iPhone 8s and two 6s in my place. I don’t remember having his issues with Sprint. I’m attaching three screenshots for speedtests done in three different locations inside our home. Not sure what will happen if we lose

Ouch. 😥 Thanks for the update even though it wasn't pretty. If you stumble upon your ticket number, pass it our way so we can check it out as well.

No uodates. I just another test while displaying full bars and LTE. Below the screen shot. I checked my email and logged into this site without WiFi and it was painful.

Hey, @carlosdia​!

I know it hasn't been a full three business days yet, but I just wanted to swing by to see if you have any updates for us.

It's good to have those examples in case engineers specifically ask for them. So if you do testing like this in the future, keep the results in your back pocket. Sorry you weren't given the ticket number, but you can always ask for it and they'll give it to you. You'll want to give our engineers at least 3 business days to investigate the ticket and give an update. I'm afraid if you follow up too soon, there won't be any update because the engineers are still working the ticket.

I did call today but was not provided with a ticket number. I also asked if I needed to provide them with the test results but they say they didn't need them. Should I follow up again with tech support?

Okay. Thanks for that information.

I also think that's a great idea to collect data in other locations in regards to the hotspot speeds. I appreciate you giving the USB tethering method a shot as well. For ticket's it's always good to give our engineers a few days to work on it. That way, it'll give them some time to check things out and give an update on the ticket.

The answer to your question is, "Yes, I've always seen a decrease."

That being said, you have to understand that I only got these two lines at the end of June, and between then and now is really the only time period where I've been doing heavy-duty exploration of using the phones as hotspots.

I will almost certainly try USB tethering as part of my testing process, but I want to do some further testing in multiple locations with using the phone as a hotspot with my computer to see if that has any influence on this issue at all.   I opened a ticket yesterday, but am not going to follow-up on it until I have some hard data to follow up with.

@carlosdia I appreciate you also being so thorough with your testing. I agree that these results lean more toward this being an isolated issue in your specific area. I believe we mentioned you having a ticket as well. Have you reached out to have your ticket updated with these results?

@britechguy these are very interesting results you've got with your hotspot speeds. Have you always seen a decrease in speeds when using the hotspot function? Also, have you tried setting up the device and tethering the data via USB to see if there's a differences and  DL/UL speeds?

This is getting curiouser and curiouser on my end.

I have found that I can get a 4G LTE speed connection pretty reliably provided I have my phones on the second floor of the house, so that's good.  What's not so good is what's happening if I attempt to use either one (a Samsung Galaxy S7 or a Dougee Y6 Max) as a mobile hotspot.   Even if the phone itself has blazing fast data the hotspot function does not, and by a factor far larger than it should be, as I know the speeds will not match.

As an example, the Y6 has the following when Speed Test by ookla is done directly on it:  P 45     J 4     DL  31.3   UL  12.9

If I am using the device as a mobile hotspot, whether I'm sitting right next to it and my computer indicates it has a perfect WiFi signal or am further away, but still with a strong signal, I am consistently getting figures very similar to the following:   P 59      DL  0.52     UL  0.51  (jitter is not reported on the PC Speedtest app).

The exact same sort of thing is happening with my Samsung Galaxy S7 though, oddly enough, it's best data speeds on the device itself are somewhat lower than the Y6, which I really would not have expected.   It probably has to do with the device size and internal antenna, as the Y6 is much larger than the S7.

This makes mobile hotspot use absolutely impossible, and since the behavior crosses devices (and it doesn't matter if I'm using 2.4 GHz or 5 GHz WiFi) it's pretty clear that it's not likely to be the device end of things.

I actually need this stuff to work, as data is more important to me than voice, by far.

Another test at 407 Spinnaker Way: 3 Bars LTE. DL 1.20, UPL 1.67, PING 55, JITTE 8.2.

Ok, I followed britech's suggestion and ran a bunch of speed tests. The biggest take away is that the signal at my place and around my neighborhood stinks. The tests were done within no more than 5-6 mile ratio from my place. I'm including addresses in some cases or at least streets crossing. All addresses and zip codes are for Williamsburg, VA, mostly 23185 zip code. All tests were down without moving and without using any apps etc.

These are around my neighborhood.

That was well said, and I can't thank you enough for sharing the feedback. I agree that getting constructive criticism isn't the easiest pill to swallow, but it's something we embrace here. We know it'll only make us better as a company, and more importantly, better serve people like you that have chosen to be with us. We've got your feedback and we'll work hard to give you the better experience and make our processes as painless as possible.

Even though I am far less than pleased about this experience as a whole, the individuals I've worked with in Customer Support (and I include you here, tmo_mike_c) have been pretty consistent in listening to what I have to tell them and taking direct action.  You, for any you, cannot control what is outside your personal sphere of control.

I once worked, many moons ago, for a telecomm giant and have been in retail and waited tables, too.   It is impossible to fix what you don't know about, and most people want to fix what genuinely needs to be fixed, so I do take the time to give feedback, constructive feedback [which is generally not the kind anyone wants to hear, and needs to be delivered forcefully but with respect to the individual receiving it], because it's the only way I have to try to effect change.

I hope that the feedback I've shared does get fed "up the chain" to someone who can effect the necessary changes within T-Mobile itself.   The problem here is not with the individuals I've dealt with, or at least not primarily with them, but with processes.

Ah, okay. It doesn't normally take this much to get an answer, but I am glad you got in touch and received an update about your area. Network upgrades should improve the service and my apologies you didn't get that answer when you spoke with us before. I know waiting isn't the most ideal answer, but I know our engineers are continuing to improve our coverage and are working to do so as quickly as we can. For what it's worth, you've been informative, extremely patient, and exceptionally helpful. I really appreciate that. I also appreciate the feedback you've given about your experience. I really wish would have gone much smoother for you.

These tests take all of a couple of seconds to run when you're anywhere.   Just download the Speedtest (by ookla) app then it's nothing more than tapping a button.  The test completes in well under a minute.  The most work comes from quickly writing down the four parameters' results (Ping, Jitter, Download, Upload).

Now, I'll add more about T-Mobile Customer Care:  It really needs to get its house in order.    The  rep I just got off the phone with, who is out of the Richmond, VA, call center was spectacular.  She was able, after a few minutes research, to give me a definitive (for the moment) answer that wasn't what I wanted to hear, but gave me the information I needed to know:   I am in an area of my town that still has only 2G speeds.    I gather that even though I show 4G LTE reception that the signal is very, very weak.  You could very well be in the same situation.   We're supposed to be upgraded, but there is no firm date for when that will occur (and I had been told by one customer service rep that an upgrade had just occurred at the end of May, which was inaccurate).

Now, why the previous two first line reps, followed by the previous two second line reps, were not able to determine this information and save myself, several of their coworkers, and field engineering the runaround my two tickets have caused remains a mystery.

For tmo_mike_c, the information I received is that my two tickets have Complaint ID Numbers 283 927 38 and 283 927 54, and that they can be located in Grand Central, under the Network tab, right at the bottom.   Both are closed with "no problem found" and the second level customer service reps who were supposed to let me know about this never did for either ticket.  That is simply unacceptable when a direct statement is made that the customer will receive a follow-up call giving the status of the trouble ticket once it is closed.

@britechguy we definitely should have followed up if we said we would. I'd like to give you a status update here, but at this point we'd need are our Tech team or our social media T-Force team to open your account and give you updates on that ticket. I understand that doesn't make up for missed followups, but I know either of those teams can look up that ticket and give you specific info about what's going on.

Same thing for you @carlosdia . I saw that you opened a ticket too and you'll want to reach out as well since the problem is still going on.

I wish I have the time to run all these tests around. I still have issues.

I guess that depends on how you define "much further".   It's a couple of miles at most.

And, no, I have not received any follow-up and the confirmation number I gave the second time is absolutely the only thing I have to go on, and it came in a text directly from T-Mobile, from "phone number" 5116.

I really appreciate your stick-to-it-tiveness here, but the lack of promised follow-up, even if the status were to be, "We still don't know what's going on, but we're continuing to research it," is appalling.   I am, at this very moment, on the phone with Customer Support, even the rep I'm working with [I'm on hold right now] cannot find the ticket number based on that confirmation number.  She has found a note in my account that a ticket was submitted, but with no note of the number (which is insane), and is in the process of trying to track down that actual ticket number.

When I submitted the ticket the statement from that Customer Support rep was that I would receive a text with the reference number I needed to use to refer to this ticket.   Obviously, that was not the case.

T-Mobile needs to get its house in order with regard to these issues, and fast.   Everyone has been very responsive when I am working with them, but no one seems to be able to pull up anything related to prior contacts which are essential to "continuity of care."

This is really great info. I'm guessing those other locations are much further away from your home, right? We'll need to have engineers focus on your home area. Have you gotten any updates on the ticket you filed? My apologies, I'm still having some trouble pulling up that number you gave me.

More data points from around Staunton today (7/1/18):

1:37 PM  1000 Greenville Ave:

         P 51 J 19  D 26.8  U 5.75

4:05 PM 90 Lee-Jackson Hwy:

         P 39 J 7    D 35.2  U 19.0

And, right now (4:55 PM), in my den on the other side of town:

         P 39 J 11   D 2.95  U 1.26

On all of these speed tests I had a minimum of 3 bars, sometimes 4, and the 4G LTE icon on and showing up/down arrow activity.

Sorry, I see I dropped a digit.  That confirmation number is 28392754.  The 5 was missing.

Another test when out today at Statler Square, which is at the corner of Statler Boulevard and Greenville Rd, gave a ping of 38 ms, 38.8 Mbps Down, 7.0 Mbps Up.  Running right now from in my den it's Ping 36 ms, 3.29 Mbps Down, 0.68 Mbps Up [Jitter 27 ms].

Just back from doing an "around the house, inside and out" tests:

Inside, upstairs:   Ping 36   9.56 D   7.41 U  Jitter 5

Outside, below the inside upstairs location:  Ping 30  6.71 D  6.77 U  Jitter 10

Inside, upstairs, opposite side from test above:  Ping 37  5.42 D  2.08 U  Jitter 10

Outside, close to below the location reported immediately above  Ping 36  7.51 D  5.19 U Jitter 5

And, back in my den:  Ping 33  2.92 D  1.50 U  Jitter 17

The entire set have probably taken me all of 15 minutes to complete.  There's no more than a couple of hundred feet, at most, between the test points and the outdoor figures are sometimes worse than the indoor ones.  It's like I live in the T-Mobile signal Bermuda Triangle as far as data goes.

Hmm. I know speed can fluctuate, but that's a bit of drastic change in a matter of minutes. Does your home have multiple levels? If so, are you on one of the upper levels when you run these tests?  I'm also curious if you're seeing your signal bars fluctuate at all. I did triple check that ticket and I'm sorry, I couldn't pull it up. We'll really need to have our Tech Care team open your account and make sure we had the ticket number right when we sent it to you.

The ticket was created yesterday morning, late morning EDT, and that's the number that came in the text message send by my support tech a few minutes before we concluded the call.

I have also noticed wildly varying speeds, mostly on the 7 Mbps Download or less, but on occasion in the high 20s to low 30s, at home depending on where and when I do the test in the house.  Sometimes moving less than 5 feet can change things, and I don't live in a steel and concrete box.  I got one reading just above 30 Mbps this morning followed by another in the same spot about 10 minutes later of 6 Mbps.

And just now, about 20 minutes later, in hotspot mode with the phone being in the same location where the 30+ and 6 Mbps readings were taken I'm getting download of 0.31 and upload of 1.17.  This kind of variability is just maddening, and isn't occurring in multiple areas within 30 minutes travel of here.

I really appreciate you posting this. It's super helpful and I can see this being really useful for our engineers. I tried looking up that ticket and I'm sorry, I wasn't able to find it. When did you file it? I know Tech Care can look in to your account and double check the number. They can also update the ticket with this awesome info you've given about your speed tests

Just FYI, the confirmation number, which I presume is the ticket number, I was supplied was 2839274  (and I don't consider that private).

As I was out and about today I decided to do some speed testing from my car (and, yes I did pull off) and here are the results:

Location                 Time          Ping (ms)        Download (Mbps)         Upload (Mbps)

Harrisonburg,VA      4:15 PM       47                       37.4                                14.3

"                               4:20 PM       44                       22.0                                18.1

"                               6:40 PM       35                       47.4                                27.1

Mt. Crawford, VA      6:55 PM       38                       23.6                                  8.69

Mt. Sidney, VA          7:02 PM       38                       25.7                                14.0

Verona, VA               7:11 PM       34                       29.3                                   6.14

Staunton, VA            7:18 PM       37                         3.16                                 0.52   (one block away from my home)

"                               7:20 PM        37                      27.4                                   5.50   (my home, outside in the car)

"                               7:25 PM        36                        2.65                                 1.18    (my home, inside)

"                               7:45 PM        39                        2.59                                 1.05    (my home, inside)

If this is useful to the engineers please feel free to pass it on.  The tower that serves my home and the areas surrounding was supposed to have been upgraded at the end of May.  As one can see, the results become hugely variable in the block around my home and generally pretty horrible.  That 27.4 speed I got outside is the first instance of double digits anywhere near to my house that I've gotten in recent weeks.
