877-335-9586

Just called my cell.

Got 2 separate calls from this number. I didn't recognize it and so I didn't answer. The caller didn't leave a message either instance.

same here...don't know who it is and they didn't leave a message.  Did not answer.

answered but no response on the other end

I got two calls from this number in the last two days. Both times, the call dropped after I answered. I called it back and the recording says it's T-Mobile, my carrier. But . . . I don't know why they are calling me. I didn't "push 1 for English" to see what they wanted. Maybe them, maybe not.

I got a call from 877-335-9586 so I am about to do something about this. Trace the number so it will go directly to the police.  If you don't know how to trace a number then look it up on the internet or ask someone like the police, or the phone company.  This works for cell phones any kind of cell phone and landline as well! You can also put a weird message not using your voice so when the caller calls you then that caller will think that he or she got the wrong number. Use another voice to do this and it can be a man's voice or lady's voice and you can decide what voice you want to use when you hear all the voices. some of these are really funny because this is to help stop these morons from calling and harassing you and your family. Look it up on the internet and you will find it. I am about to look this up right now because some of my friends have people calling and harassing them.I have a lot more tricks and secrets that most people don't even know about. Because I know that people like to act like a complete moron and guess what this person is a moron not me! So, I will be laughing because this person will not go far if they keep doing this to me. This person will end up in jail because I don't play that game.I hope this helps!!!!! Remember don't give any information out unless you know this persosn and you trust this person especially your credit card number, birthday and social security number. Be Safe and only go to people you can trust!!!!!

I've gotten multiple calls and never answer and always get a long blank message. not sure what they hope to accomplish but it's kind of annoying

I got two calls from this number today, and both left a blank voicemail. I called the number back and it is a T-Mobile customer service number.

I just got a called missed it so I called back, the person on the other end said hello, then said it was t-moble just calling to update my information and be sure everything is working fine.  I told them I was busy, they wanted me to call them back. I looked up the number and see that there are many others who have got a call from this same number. How do I report them?

called cell. I didn't answer...they left no message.

Received a call well actually more than one call from this number. Was curious and dialed back and it said T mobile?? I do have the carrier from T mobile but I am sure if they wanted something T-mobile would call and leave a message and not play phone tag. So most likely these are losers phishing for info....Beware scam artists are everywhere and are very creative in how they get info from people.

Just got a call on my cel, called it back and I get a T-Mobile recording.  I do have T-Mobile, so who knows if it's legit. I've recieved other calls from them and it always comes up as TMobile and they do answer

Wow okay. Hopefully by now you have refilled your prescription. Pretty sure it's just T-Mobile.

Its just T-mobile , a courtesy call about your service.

It's T-Mobile calling to explain the billing for new customers and take a quick survey - they ask you to rate your t-mobile network coverage, t-mobile service, and t-mobile in general.

It's not too annoying except for the painful detail they take in explaining the bill. I'm a grown up, I can figure out my cell phone bill... no need to call me to explain it again, that's actually a little insulting.

It's company claiming to be t-mobile, it's not.  

They tell you it's a survey but it's not. they are phishing for information so they could exploit your online bank access and or email.

The information you give them they will use to answer security questions to reset your accounts.

If it is really T-Mobile, then WHY do they hang up on everyone? Like me?

Just got the call, didn't answer. Called back from my work phone, the introduction says it is T-Mobile, pressed 1 for English and got an operator. I told her that I just received a call from this number and asked why. The representative said that this was T-Mobile and they were calling new customers to thank them for switching and to see if we have any questions.

Same Here I answered itt but did not respond

Received same call from this number on my cell called back and it said
T-Mobile which it isn't....didn't press #1 for English. Hung up and called customer service
at T-Mobile and reported it. T-Mobile's normal practice is to send a text message not a call.
So, keep this in mind.
