Hi,

The mobile is able to receive sms but when trying to send a new message i get a sending..... status and that's all. The message is not send.
I have checked the Message center number it is Ok
When changing my SIM to another phone ......it works
I contacted VODAFONE to send the setup.....they did it but nothing
I DO NOT WANT TO FACTORY RESET THE PHONE.
Does anybody knows something?
Service stopped or anything?

Backup all your stuff and perform a factory data reset...it will fix the issue.

Hi snest,
I have the exact same issue, since 5th-Feb-2012. It seems to be related to the stock messaging app. Don't have a clue what went wrong, but it just stopped sending messages. I have no issues receiving though...
I've checked my logs and I didn't install anything. Perhaps I did some updates, I'm not sure...
I also called Vodafone PT to check if everything was ok, and it was.
So I decided to start my own testing in order to try to narrow down the problem.
1st test: different SIM. No go, same problem, which means the problem is on the phone.
2nd test: restore the latest ROM backup (CWM). It worked. I was able to send/receive SMS flawlessly. The only problem was the backup date... it was 2 months old. My bad.
--> At this point I realized that the problem was on the messaging app. Something messed with it.
3rd test: Install a messaging app from the market and re-test. So I flashed the current ROM back (I backed up just before test #2), and when it came up I re-tested. No go. Then I installed the Handcend Messaging app from the Market, tested, et Voilá. It works.
I tested the stock messaging app once again and nothing, but from Handcent works like a charm.
So it's proven: the problem is on the stock messaging app.
A hard reset will solve the issue for sure, but before going there I'd like to try to reinstall the stock messaging app, if possible...
If your S2 is not rooted yet, a hard reset is the (only) way to go. I don't see any other way to solve this...
Cheers

Hi, I had a similar problems a little while after I installed handcent. SMS stopped sending. I had done some messing around removing bloatware with titanium prior to that, so assumed it was something I had done. I went back and defrosted all the apps I had frozen, but SMS still not working :-( I then thought to reinstall handcent, after which the problem disappeared , so in my case it was the other messaging app causing the problem!
My advice would be to try a different SMS app and see if that fixes the problem. Might be enough to get things going again.

This was the reason why I installed Handcent - to try and "wake up" the stock messaging app. Handcent works flawlessly, but it didn't solve the original issue.
I never had any other messaging software installed before, and my bloatware was removed a long time ago (October 2011) right after flashing a new Android version (2.3.5). So this was not the root cause for the messaging app to stop sending sms...

Go SMS Solved the problem?
Hi All,
Thank your for your replies.
I installed the Go SMS and merely resolved the problem of sending SMS.
But still I can not sent via stock messaging apk .

Try clearing data from your Messaging app from menu > applications > manage applications.

Unfortunately cleaning data did not solve the problem.

Factory reset. Or do a clean flash of GB stock rom.
Same difference, pick your poison. You may not like it but that's the only thing that's going to fix the problem (unless it is a network/apn/sim problem).

Most probably the Message centre Number has got corrupted...
Do this..
Open messaging ... Menu... settings..scroll down to Message Centre..
Note down the number ...
Either contact the network service provider...or first check the network provider support forums...to see if the number is correct...
once this message centre number has been corrected..you should be able to send messages...
I dont use Go SMS... but if you see the number there...you can copy it to stock messaging app..

I forgot to update this thread... Sorry.
I managed to isolate the issue, and found that the problem was on the messaging app itself (mms.apk) that somehow got corrupted. I tried to reinstall from an old APK backup, but it got worse, it stopped working completely.
After several hours and many tests, I ended up restoring a 2 month old CWM image (equivalent to a Factory Reset). Then I fully restored a 2 days old backup (Titanium Backup) leaving out mms.apk. Problem solved.
In your case, my advice is:
1. Install Titanium Backup from the market and perform a Full Backup (to SD card, otherwise you'll just loose it);
2. Factory Reset;
3. Setup the basics, access the market, and install Titanium Backup;
4. Full Restore (all files) EXCEPT mms.apk.
This is the only way to have the messaging app to work again with minimum (acceptable) data loss. Good luck.

Excellent advice Mnico

Pls Help!!
Hello Guys!! I need some help here on how to be able to send sms. I tried using Handcent and Go SMS but to no avail. However, what confuses me is that I can send sms using a different carrier sim(Like Globe and Sun. Am wondering if im missing out on anything to make it work. I have s2 from korea/olleh on ver 4.0.3.. TIA

Hi macnaque.
Your problem is slightly different from the one that is being discussed on this thread... and a lot easier to solve as well.
It seems that your problem is due to a simple misconfiguration of the Message Centre number for your main carrier. Try the following:
- Boot the phone using your main carrier SIM. Then open the original Messaging app, and open "Settings". Scroll down to "Text Message (SMS) settings" and compare the number you have set under "Message Centre" to the one provided by your carrier. (you may need to check their website or call the customer support service to get it)
I had this same issue just 5 or 6 days after buying my S2. Somehow the last digit of the Message Centre number just... disappeared. Never happened again though.

Same issue fixed
I had the same issue on ShoStock rom on my SGH-I777, Put my sim in another phone and was able to receive messages just fine, BUt when I had my Sim out, I did a simple reboot on my phone and then put the Sim back in and rebooted the phone again and everything works just fine. I am pretty sure it had something to do with the efs folder and the IMEI number because when the sms wouldn't work, I could not open the efs folder but after the reboot and the sms working I can open the folder and view the contents,

I had the same problem. I tried everything and only installing rom by odin works for me.
