Flattr this!

Although most of my friends are using 3G/s now, I do get the odd 2G phone to play with.

Today I had another crack at enabling MMS on a 2G. For some reason not much documentation, and too much misinformation out there on the net.

Guaranteed working instructions for China Mobile users below:

Note #1 – this is for 2G iPhones only. 3G and newer phones, skip to the MMS settings at the bottom of the post, and put those in Settings / General / Network / Cellular Data Network…

Note #2 – 2G users – if you used BlackRa1n to jailbreak, this will not work either, and will b0rk wireless. Use PwnageTool, and create a 3.1.3 jailbroken / boot neutered (carrier unlock) firmware, install that first, then continue.

iPhone 2G users –

Install 3.1.3
Jailbreak with usual steps.
Add in Cydia / Sources
Wait a bazillion years for cydia to timeout with the various blocked in China repositories.
Click Search
Download Activate 2G MMS

Normally we’d be done, however the MMS settings won’t let us save a diffferent MMS and GPRS name, so we need to install a specific IPCC (iPhone Carrier Setting file) for China Telecom.
As China Telecom is (at time of writing) not an official iPhone supplier, they don’t have an IPCC file, so we need to roll our own.

Here’s one I found earlier –

Download that, unzip, and throw on the desktop.

We’ll need to tell iTunes that its ok to use the IPCC file first, so close iTunes.
Now head off to terminal (or a DOS window for those on Windows), then paste this in.

Mac users:
defaults write carrier-testing -bool TRUE

Windows users:
(32 bit)
“C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1

(64 bit)
“C:\Program Files (x86)\iTunes\iTunes.exe” /setPrefInt carrier-testing 1


Ok, now open iTunes again, connect the phone if its not connected, and..

Mac Users:

Press + hold down Alt(option), and Click “Update”

Windows Users:

Press + hold down shift, then Click “Update”

iTunes will prompt you for a file.
Choose the IPCC file you downloaded.

Sync the phone.

Finally… shut the phone off again.

Once you power up again, you should be able to send/ receive MMS!

If its not working for you, check that the settings are in there –

Settings / General / Network / Cellular Data Network

(anything not listed below should be empty)

Cellular Data
APN -> cmnet

APN -> cmwap
MMS Proxy ->
MMS Max Message Size -> 300172

Tested, and working on lots of 2g iPhones.

If anyone wants to mess around with the settings for the Huawei eHome router EchoLife HG522-c (typically the ones supplied with the “3M or 4M” connection), then here are the user / pass settings.

User: telecomadmin

Useful if you want to rejig the QoS settings.

If that login doesn’t work, try this – which is usually seen on the HG226 models –
User: fiberhomehg2x0
Pass: hg2x0

The other standard modem HG520S is easier – admin / admin

Might be useful for some folks. I’m mostly posting here for myself, as I’ll probably forget and need to google it later.

From 12:00 – 2:40pm today Shanghai Telecom was experiencing router problems for servers in the 61.129.88.xx address space in the data centre at WuSheng Lu (the main Shanghai Telecom building).
This affected 3 of our servers, and one of our clients managed servers.

Shanghai Telecoms official response below:


Unfortunately once they had resolved their router issues, at around 3pm,  Shanghai Telecom decided to create some new ones, by arbitrarily rebooting all the servers in that address space.
Due to their actions, on reboot, our database server could not fully mount the data partition, and so a number of our client websites were unaccessible, as was our webmail service.

Repairing the damage caused by Shanghai Telecoms actions took around 2 1/2 hours.

Full services resumed at approximately 5:20pm

All services are currently running smoothly, although we do have some reports of connectivity issues from some clients.
If you are still unable to connect to the mail server, please turn off your ADSL modem or Router, and log onto the internet again.
(This will clear any route issues  in your router, and you should be able to connect successfully.)

Apologies for the inconvenience.
