iPhone MMS settings for O2-UK

Do you use an iPhone on the O2-UK network and find that you can no longer send or receive MMS since the last iPhone software update?

It seems that Apple’s carrier bundle settings for O2-UK don’t recognise that some O2 customers aren’t on official iPhone tariffs and so need different MMS settings to the default.

Below are the O2 MMS settings that you should use if you are not on an official iPhone tariff. For example you might be fortunate enough to still be on a Simplicity tariff with unlimited data.

Settings > General > Network > Cellular Data Network > MMS

APN wap.o2.co.uk
Username o2wap
Password password
MMSC http://mmsc.mms.o2.co.uk:8002
MMS Proxy 82.132.254.1:8080
MMS Max Message Size 307200
MMS UA Prof URL (leave blank)

Switch your iPhone off and on again after making these changes and MMS should be fully restored.

All Your MMS Are Belong To China

A warning about the GO SMS Pro messaging app in Android Market.

I have discovered that when used in a particular way the app uploads your private MMS image attachments to a public web server in China (gosms.en.3g.cn)

For example, here’s one I sent earlier –

http://gosms.en.3g.cn/D?f=NPQRRMAE200dI_ViaGoSMS

It doesn’t tell you that it’s doing this and the client settings aren’t obvious. Worst of all there is no way to delete images once they have been posted.

Try it for yourself:

  • Open GO SMS Pro and start composing a new message
  • Add some text and then tap on the paperclip icon to add an attachment
  • In the GO tab, tap Pictures and select an image to attach, then tap Send

You’ll see that instead of a true MMS with an embedded image attachment being sent, your image has been uploaded to a Chinese web server and your message now contains a link to it.

If you are using this app in place of your stock messaging client and want to be sure that your images are sent only to the intended recipient, then I strongly urge you to uninstall immediately.
