People calling me get a busy signal

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.

Hey @magenta5655286 

Is this happening with 100% of your calls or just certain callers?

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.

That is good to hear! Please do let us know if the situation changes.

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

Hey, @daddyo1425​!

I have to agree with Chris - this is super strange! What type of phone are you using? Does location matter? As Chris asked, when this happens how many bars of signal do you have? Lastly, have you talked with Tech Support regarding this yet?

Well that is incredibly strange! Do you happen to notice how many bars of signal your phone shows when this happens? Does this tend to happen more frequently when you are in a specific area?
