4G and LTE Data network speeds terribly slow

Amid the pandemic lockdown, I’ve been indoors and mostly reliant on wifi. Today I had an outage and relied upon t-mobile data to carry me through the day and it let me down. Right from the morning, I either had no connection, or speeds of 0.2Mbps with very choppy connection. I tried calling Tmobile customer rep, who was kind enough to walk me through several steps to try resolving the issue. In the end he suggested me to switch off LTE for the time being to get around 2Mbps. An hour after that, the connection dropped dead for several hours. Now its back again with speeds around 1 Mbps. Tmobile customer reps are swearing that there is no outage reported in my area and I am the only customer with problems. I know there are no issues in my phone as data connectivity is fine in other neighbourhoods, and my wife also sees same issues as me. My neighbours are on ATT and they have no issues. I even stepped outdoors and walked around my neighbourhood to test for internet connectivity speed. While it is better than what I get inside my home, it is still less than 2Mbps. How can I convince tmobile to send engineers to this area and test connection speeds on the ground with their device?

What phone are you using & where are we talking about (zip)?

iPhone 11, zipcode 95133. Tmobile coverage map says excellent speeds at my address based on customer data.

I’m not familiar with iPhones, but have you checked that your APN settings are correct? If you don’t know how try Googling it or take your phone into a Tmobile store. Are any open in your zip code? However, you are correct Tmobile reports excellent coverage in your zip - solidly!

Similar problem. Lte speed on ipad is around 0.2Mbps. Same SIM card in iPhone gives 80Mbps.

What type of phone do you have? either way, try to do a full network reset. make sure network is registered to tmobile lte when you do near by search of networks, just in case you are not roaming around, even if you are at home. It’s to make sure your bands are set correctly. and of course make sure things are under us and under automatic/lte etc if you see it.

 

assuming it’s tmobile, for android and iphone, do this and reboot if it does not by it self.

 

Home screen, tap Settings > General > Reset.Tap Reset Network Settings.Type in the device password if prompted.Confirm selection. good luck :]

Thank you. I tried that. No luck :(

Been on with tech support for the last 45 min because I have the same issue....       .20 mbps download, upload is at .01mbps....   I have an LG G8thinq at zip code of 97702...they walked me through all the steps that everyone else has talked, about with ZERO improvement, and then they recommended a new SIM card.... I'll let you know what happens when I get it. They put in a "ticket" to try to resolve the issue. We shall see if I continue service. 

@Beast101101 im currently having the same issue. Im in zip code 96818 and im on an Android device. Samsung galaxy s10+. im seeing speeds at 0.2mbps download and 0.12mbps upload... I called multiple times. They tell me that the service they're seeing is fine on their end. Finally after like the 10th time calling, they tell me they'll send a technician blah blah. The normal bs yanno.. but they walked me through the troubleshooting and ill see a very drastic change. One of the times i saw it at 60mbps download and 40mbps. So i know what its capable of. Most of the time around 10-30mbps for both. But it'll last anywhere from 10 minutes after i get off the phone with them to 4 hours. And boom. Can't do anything. I'm actually really curious to know how a new sim card is doing for you. They told me they checked mine and it was fine apparently. Looking forward to your reply. Best of luck. 

I am experiencing this and went through the steps in this thread.  In 38104.   Any new information?

Same problem!!

I'm 300 ft away from the T-Mobile antenna and the speed is awful between 1.2 - 2.84 mbps.

I'm using a Galaxy Note 10+ with essential plan, but the first 2 days with this plan the speed was 57 - 168 mbps.

 

What's wrong with you T-mobile? 🤬

.05-.12 mbps!!! Wow! this is like a 3rd world country! I was in Philippines and I would say it was a lot better there!!! This is so terrible! 95133 area code too!!!

I am getting this same coverage at 95131, 95035 and most of place I’ve been. I always check because everything taking too long to load. There is one place in Milpitas that I got about 60-70mbps but because I was close to the tower and on a weekend in industrial/commercial area. I am guessing less people less congestion.

 

If the area too congested, do something about it!!! It so terrible and I just bought a couple of new phone so stuck on this awful coverage.

Reminds me of a few places in Los Angeles.

‘IF’ there is a way to set this on your phone (Android users can do this, typically), Try and select LTE Band 41.  This will force you to Sprint (roaming must be enabled).  Sprint has a lot of spectrum in many areas.  Here in SoCal, I’ve been hitting +200Mbps on Sprint B41 (where I find it).  

Eg.  Woodland Hills on One Plug 8 5G - ~1-2Mbps with full signal on T-Mobile, and once, it (by itself) flipped over to Sprint B41, and I was hitting +200Mbps.

File tickets - or T-Mobile will just continue as usual.

We are seeing 0.7 to 2.5 M download and 0.02 to 0.2 M upload in Southern California since 01/11/21 using a T Mobile Lumia 521 with 4G support.  The problem is 24/7.  80% of the time, there is no data flow and the website would time-out.  Switching to an AT&T MVNO SIM card fixes the problem.  I also tested the T Mobile SIM card in another phone with 4G LTE support.  Speed is around 40 M, for now.

I believe T Mobile is aware of the speed issue with the 4G and 4G LTE bands.  Root cause is probably the integration of T Mobile’s and Sprint networks.  Switching to AT&T towers would be best if there is coverage in your area and the price is par with T Mobile’s.

SoCal is a pretty big area.  I don't have these issues north of LA.  If you could band select B41 and pick either Sprint or T-mobile depending on location.  5g phones can be strange with service and give worse performance in some areas.  Several 5g sites have been enabled in my area and in parts of the San Fernando valley.
