I bought a Cambridge Sciences Vector G7 tablet from Amazon UK running Android 2.3 and an unlocked Vodafone branded Huawei E220 USB modem from ########### to use whilst on holiday in Spain. I've also ordered a Spanish Vodafone SIM from ########### which I am waiting to receive.

I first plugged the USB modem into my Windows Vista laptop and checked that it worked using the Mobile Partner program and a Vodafone UK SIM. The settings I used were:

APN: internet
Access Number: *99#
User name: web
Password: web

I then connected the USB modem to my G7 tablet and created a new Vodafone 3g connection using the same parameters shown above for the laptop. However, the connection failed because 3g was already running and needed to be stopped first. The running 3g was found at settings - applications - running services tab. After stopping 3g and re-booting the G7 I was able to connect to the Internet. I also found it necessary to reboot the G7 each time I used the USB modem to connect to the Internet.

I hope my experience helps others to get 3g working on their tablets.

And you did try to set APN type to "default" (without quotes). I know that has helped before when the device refused to use the new an, even after deleting the old one. But the problem you are experiencing where it just dissappears I haven't seen before. A quick google search gave some unanswered cries for help from six months ago. If you have the possibility to use another ROM, that could be worth a try. Also, the adb log (using t.ex. alogcat) could maybe help someone help you.

Working 3G USB dongles:
Do note, your modem version can be seen on its white label written with very small text.
some modems require zerocd (linuxtool) or commands executed in windows to disable the mass storage part of it. (search google for the commands)

•* ZTE MF 639 (might need roaming enabled to get data working)
•* Vodafone K3765-H
•* Vodafone K3715
•* Vodafone K3565 / Huawei E160
•* Huawei E169
•* Huawai E170
•* Huawai E171

•* Huawei E1550

Download 3g-usb-stock1.zip for 3.0.1 stock release Acer_A500_1.141.01_EMEA_GEN3: (vermagic=2.6.36.3 SMP preempt mod_unload ARMv7)
Download 3g-acer31stock-usb.zip for 3.1 stock release Acer_A500_3.019.01_COM_GEN1 (vermagic=2.6.36.3-00005-g5dff38c SMP preempt mod_unload ARMv7)



HOWTO:
- first: Backup your /system/build.prop on the tablet , just copy the file to a safe place, as its important if you wish to do a online update later on.
- updated zip, so you can now install the zip as an "update" using ClockWorkMod/CWM if you got this installed.
- download the "system.zip" attached to this post.
- unpack all files to a temporary folder ie. C:\myfiles
- assuming you got adb running
* push files to your tablet with;
•adb shell mkdir /data/local/temp

•adb push C:\myfiles\system /data/local/temp/
* next run
•adb shell
* then run all commands below in the shell
•su -
•mount -orw,remount /system (i forgot this line, ITS IMPORTANT)
•cp -a /data/local/temp/* /system/
•chmod 4755 /system/bin/pppd
•chmod 4755 /system/bin/rild
•chmod 755 /system/bin/rild.run
•chmod -R 755 /system/etc/ppp

If you done these steps correctly, and you reboot.
you will now have a working 3G option in Settings -> wireless networks
so you can configure your APN now and connect to your 3G network.
and you got it all automated with honeycomb 3g! no terminal needed to start 3G!

HINTS
- Other reports are to remember to "Disable PIN" on the card.. I have no personal experience on this part, but check up on it, if its not working perfectly, or no data, but network is ok.

- I got reports back about enabling roaming to make it work, and also remember the story from Folio100 with 3G dongles..
so if you cannot get data connection at all, try to enable roaming and see if APN does not appear which matches your isp. maybe read you ISP website to confirm it.

- If you happen to remove the dongle, there is a solution (using as example gscript) to restart the ril daemon.
in a shell you can restart the ril-daemon if you reinsert the 3g usb dongle.
do it like this in the shell:
su -
stop ril-daemon
start ril-daemon

run putty
click serial below port number and then change port number to one previously founded
click open
write atz and press enter, modem should answer ok
write ati and press enter, modem should give name, type, etc
write AT^U2DIAG=0 and press enter, zero cd is now disabled

You need also put sim card from modem to any phone and disable pin checking

ok I've been working with this further. I've took the default t-mobile apn entry and have been able to change it one section at a time to try to determin what setting change is causing the entry to disappear.

when I got to the MNC entry and changed it to 410 from 280 and saved this is when the APN entry disappeared.

I'm wondering if it's possible to leave the MNC entry at default and get it to work?

ok I have confirmed, it is the MNC setting that is causing the problems. I did a reset back to defaults and then went into the t-mobile us apn and changed only the MNC setting from 260 to 410 and saved the APN. this caused the t-mobile US APN to disappear.

any other ideas guys?

please bear in mind that I have confirmed that my modem is unlocked. I was able to get it to work perfectly with my AT&T sim under ubuntu linux 10.04 LTS as a 3g broadband modem using the AT&T settings

I am sure that there is something missing from the
firmware on the tablets and that why we are having these
problems

I've given up on it for now. It seems to be an issue with the firmware on the A816 as the modem will work if it would let me create a new APN with the correct settings. The modem works fine using the same settings as a broadband 3g modem on my linux netbook.

Yes having the same problems as well and have tried lots of different ways, and also thing there is something missing from
the firmware that is stopping it working which is a shame, as would be easier to just plug the dongle in that use tethering
with my phone, hopefully somebody can look into this and give us a fix to get it working
here is what I have tried so far
here is a link about getting 3G Dongles to work with Android
