Galaxy S II - My phone won't let me send SMS but it lets me send MMS?

[kapesha]

My Samsung Galaxy S2 (T-Mobile) won't let me send text messages.. I can receive them but I can't respond back. Also, I can send MMS but not SMS. Whenever I send an SMS, it just keeps loading and says "sending" then finally says 'failed' w/ a red ! sign beside it. I can also call people and receive calls but whenever somebody in my contacts call me, it always say "Unknown number". I already checked my message centre number and it has the right number in it so I don't think that's the issue. I thought it was because I just upgraded to jellybean 4.1.2 but then I downgraded to ICS and it's still like that.... help?

Hmm....this is an interesting problem. What carrier do you have? Also, what APN settings are you currently using?

T-Mobile... and I'm not sure about the APN settings... how can I find that?

T-Mobile has put together a guide on how to check the apn settings and reset them. Here you go:
Reset default APN settings for data and picture... | T-Mobile Support

*sigh*
I feel like I already did everything...
checked if the message centre has the right number
cleared data/cache
reboot
took out the battery out for awhile
did a factory reset

I still can't send a txt message, but idk why it lets me send an MMS though......

Unfortunately, it didn't do anything....

Alright, we can still troubleshoot. When did this issue start occurring? Was it during a time when something new was installed? Is the phone up to date? Are you aware of any issues with T-Mobile in your area at the moment (network connectivity, upgrades to the towers, etc.)?

It started when I finally upgraded to Jellybean 4.1.2. But then like I said I downgraded and went back to ICS 4.0.3 and it's still won't work.
And I don't think something's wrong with T-Mobile at the moment since my family's phones are all good. This actually happened to my brother a few days ago, but it was resolved after my mom changed his phone from 2GB to 4GB (I think that was about the internet/web/4g limit) and it worked... she did the same for me but it's still like this. We contacted T-mobile and their suggestion was to clean the cache/data etc. and turn off the phone but yup it didnt work.

What I don't get is how I can receive msgs and send a message as long as it's in MMS (it doesn't have a problem when I do that, and it sends the msg fast) but when it comes to SMS it won't..

I have a theory that it might be a network issue. If your brother's phone was resolved by an account switch, it sounds like a network issue. What baseband do you have? It's found in settings and then about or status I believe

Maybe I should try contacting them again later if nothing doesn't resolve this..
and its baseband is: T989UVLE1

Nevermind..... it's finally working.
I called T-mobile today and apparently they had my sent message blocked, and they had no idea how that happened.
They unchecked it and now it's fixed!

Awesome! I thought it was a network issue. I'm glad it's fixed!

I have the same problem can't send SMS text message I can receive not send.
calling t-mobile on Monday, everything worked fine until, I upgraded to 4.3 rom

 

[Lhaime Del Rosario]

where can i fund the t mobile to call it?

 

[melisaaallen]

This is happening on my Note...we're on Net 10 (through AT&T network).

the solution to to the same issue I used was to put my Sim in a non android phone (Nokia or Iphone etc) then the messages came through. I returned the sim to my phone and all is good for now. My Help Center said the sms were held up in the system, as it does and can happen from time to time. 2 options were: 1. try Sim in non android phone to clear the blockage... 2. Get your service provider put in a request to delete messages held up then to re-set phone after hour or so. (turn phone off for 30 secs)
