recieved phone call. no one answered. i am a t-mobile carrier.

Ditto
except my purchase was on Monday, December 20

Very unusual and not to mention unprofessional.

Changed my Tmobile family plan Jan 1, got a call from this number a little after 8 PM Jan 5.  I answered and they hung up right away.

recently upgraded my cell phone at tmobile as well, got this call 3 days later. Missed call, no message, today only (first time).

same exact thing... had my new t-mobile phone for a week and this same maryland number has called multiple times, never leaving a message.

junk call

It seems to be a lot of junk when switching to a new T-mobile new plan, T-mobile need to do something

It must be related to tmobile because I just got my phone. No one has the number.  In fact , I don't even know my own number enough to give it out. I have tmobile.

Got 3 calls in a row from this number. Each time it hung up. Damn annoying. I am a tmobile customer.

My phone is a tmoble and i got a phone call from this number

I have received calls from this number 3 days in a row and they will not leave a message so I will not answer or return the phone call.

Just upgraded my t-mobile phone last week and started getting calls at least once a day about 2-3 days after I bought the phone.  They do not leave a message and call during the day or evening.  It is indeed annoying.

Also new to T-mobile for the past week, keep getting calls from 240-699-8960 too. Caller never leaves a message so that tells me its not terribly important, even if it is a follow up from T-mobile's customer svc. So because its a lame call I'm simply ignoring the call till they get the message or I may do the work of contacting them myself someday and scream: "Put me on your do not call list [***]!"

Happy misery! ;-)

they won't leave a real message, just 5 to 20 seconds of silence on my voice mail. t-mobile phone here too.

Repeated call from the above number. No identification. Number unknown to m
