People calling me get a busy signal

New customer, just realized T-Mobile’s spam blocker is overzealous, blocking many family & friends.  Watch out! 

At work, or at home, etc. I’ve had it show a particular phone number called me 32 times. They said they called 3 times and explained the problem when dialing it wouldn’t go through at first, then again it just hung up on them, then 3rd time it went through but never came to a voicemail prompt. 

if i call my own cell phone number from my work phone, it will ring and ring, then will eventually go to busy signal. The same thing will happen (it will go to a busy signal) if i decline the call. What the heck is this? I pay for phone service, yet i get no service. I have constant missed phone calls, and my phone never vibrates or rings. This is the most pathetic phone carrier I've had. You definitely pay for what you get.

I am having the same issue as some of the people above.   When someone from a company calls me, they get a busy signal. I cant supply the rep with a phone number because the company has multiple land line numbers. It would also be a bit tedious to try an obtain all the effected numbers to give to Tmobile.  (Google Pixel 2)

I have exhausted all trouble shooting methods such as:
turning off the phone

factory reset (which I will not do again)

phone reset (under my phone option) 

test inbound calls from multiple people in the same area code (I can get their calls)

total clear out of any / all blocked numbers

Checking signal bars when I was told the caller could not reach me (its 3-4)

Change physical location (did nothing)

Advised company of faulty land line equipment and / or  other equipment. Was advised by company that other people in the same area code are able to receive their calls (but not me)

• contacted Tmobile tech support with days / times callers reached a busy signal. Did some minor trouble shooting with over the phohe rep , but problem still persists

If anyone out there has had a exact / similar issue and was able to resolve it, post your solution here.

This is a common and very vexing issue. After much troubleshooting I figured out that it was the Tmobile NameID spam blocking service. I disabled that and the problem magically went away, after trying virtually everything else (to include SIM swapping to other phones).

Turn that off, and perhaps DIGITS as well, and you should be golden.

1st check call blocking to make sure the phone number(s) aren't listed. Go to Phone app, Settings, block numbers. Mine wasn't listed though i added the number left it for awhile then removed it from that list. Unfortunately that did not work.

Same thing with me and I also have a Galaxy S8. Since the last few updates my phone has not been working properly. Just recently I've learned that parents have been trying to call me for days and they've been getting a busy signal. I am able to call whomever but not receiving calls is not acceptable right now. I have some sick family so my parents not being able to contact me is pushing me toward another carrier.

I have been having connection problems for almost a year. It's intermittent. People calling me get a busy signal when I'm not even on the phone. I run a business on my phone,  so unfortunately after many years with Tmobile,  I may have to change carriers. Who knows how many thousands of $ lost business in the past year. Awful!

I am having the same issue. Everytime the person tries to call me it would ring one time then say ”this line is busy” and the phone hangs up. I use to receive call from the person but now I cant.

My doctor office stated again that they tried to get a hold of me for a week with nothing getting through and then it did. I don't know what else I can provide because someone has to tell me that they have tried to call and can't get through.

To my knowledge, it is not happening when someone is calling from another cell phone, every time someone has told me it has been from landlines. Yesterday my doctor's office tried to call multiple times just to get a busy signal, they finally called my office phone and left a message, thank goodness. So I have no idea what I am missing.

My husband, who is on T-mobile, does not get half my text messages, I get all of his, but about 1/3 of mine don't go through to him. This has been very frustrating because I don't know what he has not received.

I work from home so I am in the same location all day every day. No signal problems.

I am having same issue and took my phone off wifi calling like you did months ago. Still getting message on my work phone from my neurologist, my doctor's office, my bank all saying they have tried to call me all day but just get a busy signal. How many other people have tried to call me just to get same that I don't know about. I own a company.

I need these calls to come through or be able to leave a message.

I have a Samsung Galaxy 8plus, I never had this issue with Verizon, ever. I want to stay with T-mobile but I am getting a feeling this is something with the network.

Thank you for your responses.

This happened at home office in an excellent signal area and on WI-Fi calling.  Using a ZTE.  Discussed this issue with tech. several times.  Finally received an answer that seems to be working.  Will get back if not.  Apparently, having my Connection preferences setting to Wi-Fi preferred was (maybe) causing this situation.  Tech asked me to place setting on Cellular preferred which uses Cellular Network for calls.  If Cellular unavailable, use Wi-Fi.  Makes sense, I guess, since I am in a very strong signal area.  However, my Wi-Fi signal was also strong, so I do not know why that would cause a busy signal for callers.  In any event, calls seem to be going to voicemail now when I am unable to answer instead of a busy signal.

On my android:

Go to: Settings>More>Wi-Fi Calling>Cellular preferred
