Sprint iPhone 5 can't send MMS to non-iPhone users.

I have the same issue and its not your IPhone 5 as the moment I booted up my girlfriends 4s from the iOS 6 update her ability to send pics in iMessage was broken too. I honestly think its a bug in iOS 6. I've tried restoring, toggling the iMessage, rebooting and turning back on. I've tried removing my iMessage account and re adding it, nothing worked. I'm waiting for apple to fix it. I'm doubting a new phone would resolve it, but it could as this is not effecting 100% of devices on iOS 6. I know several who have no issues which is all the more frustrating but I'm really just waiting as it seems to be widespread

After getting my new iPhone 5 I can only send and receive texts from other people who also have iphones... I have been getting phone calls from people who texted me to ask if I received their texts. I never did and they couldn't receive mine either. Through a process of elimination I tested all of my typical text contacts and only those with iphones can recieve my texts. I'm on AT&T, not sure if its a carrier issue, or ios6?

Whilst iMessage and SMS use the same iOS interface they send differently and to identify which protocol is in use the messages are colour (color) coded.

iMessages sent between iOS and OSX devices are blue and are sent via the Internet.

Standard SMS messages are green and sent via traditional mobile networks.

What i expect all you Sprint users are sending/receiving are iMessages and NOT SMS.

You may need to check that Cellular Data is switched ON under

Setting/General/Cellular

and the Send as SMS is ON under settings/Messages.

Also toggle iMessage off to see if that forces messaging over SMS.

Caveat there are some problems associated with SMS/MMS which are carrier/sim card related.

Some sIm cards provided by network carriers hide an important set of settings in iOS and this prevents you from manually altering certain settings necessary for sending SMS/MMS.

I don't know if Sprint are among those.

I turned off iMessage and now I can't receive any texts. So it looks like its a carrier issue and I'm not able to send SMS messages. Thanks Keith as your info on the color coded texts allowed me to see clearly that I was only able to receive texts via iMessage when turned on. Does anyone know of an easy fix short of calling AT&T and trying to get them to address the issue?

IM ON VERIZON and have the same problem.. Dont understand it

I just called AT&T regarding this issue and the person I spoke to in tech support said when I upgraded from my old iPhone to my iPhone 5 and the service was transfered to the new device, they did not turn on the text messaging plan. This is why I was was only able to send messages through iMessage and not through SMS. While on the phone, the agent turned on text messaging and asked me to send a test text to a number he provided. It went through perfectly and he also texted me back to confirm. So, its a simple fix. Just call your carrier and alert them of the issue and they should be able to fix it quickly.

Have you tried disabling imessage? I have the same problem until I disabled the imessage. The imessage only works with those whose has apple products.

I reset my network setting and now I can send pictures to contacts via text. REALLY annoying that I cannot have WIFI even set up ... Even if I turn off the wifi it still does not send the pic "File undelivered" . So I have to reset network settings and not set up wifi. PLEASE FIX!

SPRINT- IPHONE5

I was also having the same issue. I received my iPhone 5 almost a week ago and after a few days I noticed that I couldn't send or recieve MMS from people that don't have an iPhone/iMessage. After doing my own list of trouble shooting and then contacting Verizon Tech Support and them basically repeating the trouble shooting steps I had already done myself, ultimately it lead to me doing a complete reset of my phone (Erase all Content and Settings). Now here is where I believe the problem is. I restored my iPhone 5 from a back up of my previous iPhone4 that was on the AT&T network which has different settings and which somehow changed the MMS setting for Verizon. I believe iMessage uses data and that is how picture messages were able to go through to other iphone users.

So basically I had to go into settings--->General---->Reset----->Erase all Content and Settings and then set it up as a new phone without storing from my previous back up which would put me back into same position. Again, this is because I restored a back up from my last iPhone that was set to AT&T settings and porting my number over didn't seem to be the issue at all.

The only issue now is to manually replace the content(pictures,apps ect) that I had previously.

Im having the same problem... my network goes in and out i called Sprint and they told me that on their end everything works and the issue is an Apple issue and i have to take it to an Apple Store

I had the same problem with my iPhone 5 on iOS6 on AT&T. After a month and a half of my phone not working right I decided to call AT&T. The tech spent 25 minutes trying to figure out the problem. Nothing seemed to fix it. Then finally he asked me to go to Settings>General>Reset and to select "Reset All Settings". I did that and the phone rebooted and boom it fixed the problem and I was able to send MMS to a tmobile blackberry as well as receive pics. I also tested it with an android phone on the Boost network. So those still having that problem should try this. It might be due to the fact that I restored from my iPhone 4 back up. The downside to this reset is that you're gonna have to set up all ur settings back to the way u had them, small price to pay to get the phone working one hunet. Cheers.

Perhaps you didn't notice the word sprint in the title. Not to mention the fact that the post is almost a year and a half old.
