No se reciben llamadas y los mensajes de textos se demoran

i have the same problem for about 2-3 months now.  I have called them twice so far.  Once when i called they said their tower updates was not updated on my number in our family plan.  that didn't fix the problem.  The second time i called them starting over to the explain the problem, which ended useless wasting my time.  Has anyone received any response back to any of these forum users from Tmobile tech support?

Now after seeing this thread seriously thinking of changing to a different network.  

I've been having this issue too, since at least February 2018 when I missed a bunch of urgent calls and texts from multiple family members. Since then, it's been happening randomly -- sometimes texts are received immediately and sometimes it's a delay of anywhere from 5 min to over an hour. Multiple contacts (people in my phone, random callers, 2-factor authentication bots) and multiple locations (home, work, coffee shops, restaurants, inside, outside); there's no discernible pattern. Sometimes the phone doesn't ring either and no missed call in the log; I just get a voicemail notification and then come to find out I have, like, 10 or 15 voicemail. No idea how many business-related calls I'm missing from people who don't leave a voicemail. I'm in a large city and my phone shows good reception but is seems to disconnect from the network periodically. Tried clearing the cache and restarting the phone as recommended by T-mobile, no help.

It's not happening with other family members on my plan (one of whom had the exact same phone as me until last month), and I'm not aware of it happening to friends on Tmobile/other networks, so I thought it was just my phone until I found this and other threads complaining about this issue and T-mobile's lack of response. I've been a T-mobile customer since 2008 but I'm thinking of leaving because of this.

My Husband and I have been having the exact same problem. It started a few months ago randomly here and there with our Samsung phones. We recently got new Huawei phones and the problem seems to have intensified recently. And we are both missing extremely important phone calls and texts message between each other and with other people on other networks. It's extremely frustrating. With our upcoming move and our family being separated for several weeks we would hate to miss interactions with each other and our kids. Not to mention important phone calls for appointments and moving companies.

There is a lot of online discussion about this same problem.  We have 3 phones w/T-Mobile service and we are all 3 having the same exact problem.  One phone is a T-Mobile and the other 2 are not.  Sometimes a call will ring thru, but it has gotten to be most of the calls don't.  We are testing using the 3 calls from different locations and it happens everywhere we go.

My wife and I had the same problems (incoming calls went straight to voicemail and delay receiving text messages) for a while. We went to T-Mobile store and had SIM cards replaced, but the problems were not resolved. Out of frustration, I switched from 4G LTE to 2G for both our phones, we have been able to receive calls without any problem and text message delay without delay for more than two weeks now. Personally, I think that all the subject problems are related to T-Mobile 4G LTE itself. T-Mobile may have introduced bugs into its 4G LTE during the latest update by accident (?).

Not sure when t-mobil will fix this. Lately customer service told me to delete old messages to make room for new(never received) messages, DIDN'T WORK.

Will they take action when people loose important calls from loved ones, calls from work or a doctor missing calls from patients, a businessman never receiving calls from customers?

Wondering if t-mobil will reimburse people who lose patients/business because of issues with their network or when t-mobil starts getting sued in such cases?

Seriously thinking about emailing the CEO, found his email on twitter(link below), hoping the address is correct and he gets the email. Maybe others should email him too.

John Legere on Twitter: "Email me John.legere@t-mobile.com… "

Definitely still an issue.  I had this constantly on my OnePlus 8T (bought from T-Mobile) and after two SIM card changes (i.e. tried 3 different SIM cards on the phone), T Mobile checking the towers (whatever that means - all looked good on their end) and even doing a warranty replacement (T-Mobile charged me $20), I finally got fed up and decided to cut my losses (still have over a year left on EIP).  I bought a Pixel 6 from T-Mobile and, earlier today, someone called me and the phone call only came through on the Digits app on another line but did not come through on my Pixel 6.  I tried to call back on my Pixel 6 and the call would not go through (I had Wifi Calling enabled).  I had to toggle Airplane Mode on and off to reconnect to the network and place the call.  Very frustrating.

I'm on a family plan with my parents. Many of our contacts are shared between us, like my siblings and other family members. Today my mom asked me if I called her at a certain time but I didn't. Her phone said I called her. I noticed three missed calls from my sister. I asked my sister and she said she didn't call me. I want to know when I'm getting a call and when I missed one. I don't need to know if my parents are getting calls or missing them on their phones. 

This kind of issue happens across all carriers. The reasons for which can vary and would  require someone with the tools necessary to look at things for you. So basically I would call or message the team force team and explain the issue to them. I would also pay close attention to when this happens so that maybe a pattern can be formed. For example, delayed texts only occur when messengering person X from Verizon. Or maybe delayed messages only occur while messaging iPhone users.

You can reach T-force by dialing 611 on your phone or over social media like Facebook/Twitter.

I appreciate all the testing you've done and I wish it was resolved. I'm not 100% familiar with this phone, but do you have the option to change the band to 2G, 3G, or 4G to see if messages and calls work a little better? It can be kinda tricky getting something like this resolved but this is another good test to see if it's related to a certain frequency.
