Hey after 2 months of using my 3G, lastweek, my 3G icon is gone and only full bars chinaunicom and ... I still have 150RMB on my card. I have tried evrything re-input apn, restart my ipad, reset network setting, remove reinsert sim card still no 3g icon and cannot connect to internet outside wifi network.

Anyone can help before i get a new sim card? My sim is 399RMB with usb dongle included at 80rmb per 1gb of data.
Thanks.

I need some help please from anyone who is willing.

I bought a SIM card in Qingdao for my ipad with the RMB 1200 plan. It works in Qingdao, Shenzhen, and Jiangsu but not in Beijing and Anhui. It works in Hebei when I get far enough outside of Beijing.

I know it is not my iPad because my friend has the same 3G, 64g with a qingdao sim card and it does not work in the same places for us.

We went to Unicom in Beijing and Qingdao and they could not tell us whats wrong. I am guessing it is a setting on the iPad?

The unicom wireless mobile usb device that I put into my macbook works fine everywhere and so does the internet on my phone which is also using unicom.

Please forgive me if this is a stupid question.

Are you using "3gnet" for you APN, username and password?

Do you have roaming enabled?

Thanks for the suggestions. I have roaming enabled. I tried CMNET for all three entries and then 3gnet for all three but nothing. It says "Could not activate cellular data network ' You are not subscribed to a cellular data service'

Any other ideas? I am guessing it has to be some setting because of the fact we took the card out and put it into my wireless usb card and it worked.

My other friend just brought his iPad along with 3g service from unicom and he has the exact same problem. So all three of us now. I am not sure if this help but now my safari is frozen up so to check I have to go to my gmail client.

Any other ideas? Thanks!

Okay got it. Had to capitalize the 3GNET. Before I just had cmnet in there as user name. Nothing for password or username. Thanks for all the help!

I am suspecting china unicom changes their setting depending on the place. 2 months ago i am using my ipad in zhuhai to shenzhen without any issues. After 2 months, the 3G icon has gone. I never change the apn (3GNET) ever since. I have transferred my sim to newly bought ipad from us and also no 3g icon.
Any carrier from china that will work on ipad?

My 3G sim is now working back again. Check my post on another thread.

In short, my iPad can not detect my sim and showing NO SIM even I power on my data device.

Any one who have tried manual cutting?
Thanks in advance.

There are many different types of Sim cards, some of which after cutting down works on iPad, but some not.

It just work when you install it. For some types of sim cards, maybe manual APN setting is needed. If so, please just input APN as "3gnet" and leave USERNAME & PASSWORD as in blank.

There is another way to get your iPad connected to internet. Establish a Mobile WiFi hotspot for as many as 5 WiFi-enabled devices (iPad, celluar phones, iTouch, Windows PC, Mac book, etc) to get connected.
