Why am I randomly not receiving texts?

I have this same issue and it should be unacceptable! It happened on my previous phone (iPhone X), but did not appear to happen in over a year. Recently purchased an iPhone 12Pro Max and I am missing multiple group chat  messages/conversations and messages from individual people. 
 

The messages I am missing are from both iPhone and Android users. I know I am missing them because people are sending me screenshots of the conversation that verify I am not receiving messages since they don't show up on my end. I have restarted my iPhone, and have ensured that it happens when I am both connected to WiFi and only connected to T-Mobile’s towers. 
 

Has anyone figured out a solution?! I have missed important texts regarding work that I would never know about if coworkers had not sent me screenshots. Also, I missed a text about a family member having a medical issue and having to be sent to the hospital (figured that out by receiving a phone call since I never responded to the text that never appeared on my phone). Who knows what conversations I am actually missing. 
 

I am extremely frustrated and this should not be happening given the amount of money I pay T-Mobile every month.  

I am having the exact same problem as everyone else here with random missed texts. Wi-Fi on Wi-Fi off, from an Android User or an Apple user, the randomness and weirdness of the missing texts either that I send or that are sent to me continues to happen. What is going on here?! Any of us who have a business cannot run a business this way and I'm seeing that T-Mobile has not responded in a way to adequately address this problem which is deeply disappointing because I like TMobile in most other regards but I just can't have people try to contact me, and me them and never know if the messages have been received or sent. it's incredibly frustrating. I hate to say it but it seems that this issue is widespread and won't be resolved until they lose enough business. Come on T-Mobile, we all expect better from you and you're just showing us that you can't or won't fix this problem that is clearly not a one-off or just isolated to Apple.

This one is easy. has done it to some of my android (mostly lg’s) phones.

pay attention! but it’s straight forward.

turn off wifi.

if you do NOT use it, that’s fine, you can get rid of it after.

download google messages from the play store. keep wifi off after you download it and install it.

install it, accept and permit all necessaries access to your phone.

simply go to and enable chat features, it will either ask you or go under settings, in the messages app. accept whatever! let it set up until it says ready to use or chat features are active.

should start working almost instantly or within the minute, and texts etc will start going thru.

once that happens, TURN ON wifi, so it syncs in the system.

that’s it. use the phone like you always have.

keep using messages or get rid of it and go back to your phone’s messaging app if you like.

I had mine on, but I believe it is irrelevant if you have wifi calling on or off.

this little process always and magically corrects this problem. this is a wifi/data configuration thing that needs to be tweaked, corrected, once you got a new phone with the same num or simcard that has been transferred over. even if the phone is defaulted to stock or simply the phone has not been “refreshed” in a while.

if you already do use messages, follow the same steps. if it was already on, turn it off and restart the phone, then do the steps from above. :]

I have been dealing with this problem for MONTHS!!!  And it is driving me absolutely crazy!  My husband had me update my Messages to the Chat thing?  I don’t know.  It wasn’t an option when I first started having issues, but when I reactivated Messages, it automatically updated it.  So I am hoping that worked?  But then I promptly switched back to my other texting app (I had the problem whether I used Messages or my other app).  I’m hoping that by upgrading the Messages to Chat that it adjusted something in the system that will make messages go through.  

I am having this exact same issue and I have yet to hear/find resolution! I’m thinking I may just switch carriers to resolve it. Has anyone else figured out how to prevent the issue?

I may have figured this out. It seems if I'm connected to my wifi network, the issue comes up. Note that I am not using wifi-calling, I'm simply connected to it for internet at home so I don't use up my data plan. Seems being connected to wifi is what's causing this. I've stayed off my wifi for the past 2 days and I haven't experienced the issue. I never had this issue with TMobile branded phones, so I think this is something that only comes up with non-TMobile branded phones.

I get the same issue. On the face of it, it's almost as if my connection to the cell phone tower goes to sleep if there's a period of inactivity on my phone and, at this point, my phone only pings the tower every hour to see if there are any incoming text messages to pick up. I can make it check immediately if I send myself a text message, though. I don't know the true cause, but it is annoying as heck.

I'm using an unlocked AT&T phone, Galaxy S7. I've used unlocked phones in the past with T-Mobile network, though, never had any issues. So, I don't think it's the phone.

I have the same exact issue as you describe above. When I discover that I am no longer receiving text messages, voice mail activities or phone calls.

I text with customer service to have my phone line refreshed. This request usually does the trick. I am currently waiting for the massive amount of missed texts to come through.

I am going to contact Network support Monday to see what they have to say about this.

Best of luck.

Same here!  My wife and have have recently seen this first hand on one of our family group texts along with a couple of other group groups texts.  Now we are really considering moving back to Verizon and paying a little move for reliability.

Any luck yet @stjp​? Same with the phone calls for me. The phone could be in my hand at the time and nothing! Also very random. Not on certain days, certain people, etc.

The only thing I've come to learn on my own is my phone doesn't have band 12, but this issue still makes no sense as that shouldn't effect texts and calls, I don't think. Seems like it would make my data work better in certain buildings and allow me to to voice over LTE which I didn't even know was a thing.

No, I did not receive anything and now I am also having an issue where people call me and it goes right to voicemail with no notification of a call.

I already contacted TMobile before making this post and to be honest this has caused so many complications I'm ready to switch to another carrier. Thanks to everyone who tried to help.

Have you gotten an updates on it? Sorry it's still going on but there's usually notes from the engineering team with a status.
