I can't send an sms/text from iphone 4S (iOS5.01)

I can't seem to send sms text messages to a specific VALID contact from my iPhone 4S (iOS 5.01). I get a "message send failure" indication.

I have inserted the full area code, and try everything listed from Apple Knowledge Base support.apple.com/kb/HT1337

I have also tried restoring my iPhone 4S, attempting to send an SMS from a fresh phone without restoring my back up and nothing seem to work?

Its definetly not an issue with my carrier, as I tried inserting my sim card onto my old iPhone 4 (iOS 5.01), and I am able to send the SMS.

Does anyone know what could be causing it? Is anyone having the same issue?

Please help. Thanks.

iPhone 4S, iOS 5

Once I got the new phone back, i plugged into my mac and did a restore from back up! I did that for several times I was still experience the same problem, so I was why don't I try restore from iCloud "luckily I did a backup before handing my old phone back to apple" dada it works. So I figured out why, is because when I did my back up with my mac, I was using a third party data cable, so the backup wasn't done properly therefore don't use third party product when you are doing such an important thing...

Hi there!


I bought an iphone 4s in NZ and had the same problem here in China Xi'an once I put my old SIM card into 4s it doesn't work and I contacted to CMCC they got no idea on it. I keep trying to fix the problem then I go to "setting"and go to "phone option" what I found is that my phone number was 0000000000 it was weird so I changed it to my current mobile number e.g. 136xxxxxxxxx and go back .Finally it works on my phone.Hope it helps you guys.

Hi All,

I've got a iPhone 4s and am using it in France under the Orange network... I've also had the same problem that it will not send regular SMS. It comes back with the "Message Send Failure". I have two things that have worked for me... (one is better than the other.)


1. Permanent Fix: (so far... crossing my fingers) I had my husband's number (not an iPhone) under the 'mobile' heading in his Contact page. I changed the heading from 'mobile' to 'other' and it works just fine now!

(I think this has something to do with the network not recognizing whether the phone in question is a mobile or a landline.)


2. Work-around Fix: If that doesn't work above, what has been working for me, before the above fix, is when I want to send a text message, I go to Phonebook, find the Contact I want to send the SMS to, press the 'Send Message' button, type my message (or paste it from before) and then the message sends. But this needs to be done EVERY message that you send... even if you just got one from them 10 seconds before.


Good luck to everyone... I find this problem quite weird and can't figure out if it's the network or the iPhone's problem.


Cheers,

RachaelJayhawk


PS -- I had tried every other fix offered here and on the iPhone support site before finding this fix!

I had received texts from my carrier, AT&T, so I expected to be able to send texts, but kept getting the "Failed to Send" response when attempting to send texts/SMS and iMessages with my iPhone 4S.


I turned my iPhone off and turned it back on again, but I still wasn't able to send text/SMS or iMessages immediately. I'm not sure if I needed to wait longer after the restart of my iPhone, but I had my Cellular Data off as I had been at home on Wi-Fi, so I turned Cellular Data on and tried again. Finally, I was successful in sending the messages I had been trying to send. When I switched Cellular Data off again, I was still able to send messages, which is what I was hoping/expecting.


So, I'm not sure if the restart did the trick and that I needed to wait a bit longer before attempting to resend, or if I needed to connect to 3G to send my first message, but I am able to send messages now, thankfully.

Had the same problem, i hope this helps.. Basically just changing ur sms centre number to your current operator.:

Well this is the way how to change sms center on iPhone 4S


Step 1 - Checking what number is set as your SMS service centre number


Launch your iPhone keypad and type *#5005*7672# and Press Call/OK


You will get a response that tells you the number that has been set as your SMS service Centre number.


Step 2 - Erasing the incorrect SMS service centre number

On your iPhone keypad, type ##5005*7672# and Press Call/OK

You will get a response that tells you that the service centre has no address or something to

That effect. It means it has been erased.


Step 3 - Setting the correct the SMS service centre number

On your iPhone keypad, type **5005*7672*+xxxxxxxxxx# Press Call/OK

You should get a response telling you the number has been set. later there is a notice stating that the smsc successfully changed.
