Hello Arun,
Well i too switched to Yasomite and found out my 3g dongle is not working at all. There were modem interfaces in System Preferences > Network but i deleted those interfaces following other crappy fix for yasomite 3g dongle issue. Now even i plug in the dongle, i dont get any interfaces rather than Ethernet and Wifi. Do you know any ways to get my 3g Dongole interfaces on??
Thankyou already.

I have exactly the same problem than Arun. I delete the zte mf 190 interface and now i dont know how to add it again. Thanks for your help!!

HI There
Thank you so much for this post!! I was struggling for the past 3 days with this issue. ZTE modem working perfectly now.

Thanks for this – worked on my ZTE MF112 on MacBook Pro running Yosemite. Despite being told that the dongle was "incompatible" with the new OS. Told to go and buy a new one – fortunately I tripped over this hint.

Hi. Thanks for your support, but I have not been able to establish a connection yet. The message that appears is "Has not been able to establish a connection with the PPP server"
Help Please.

i get this error "the communication device selected for your connection does not exist. Verify your settings and try reconnecting." I have followed this guide step by step twice, i cannot find a solution.

Hi. I followed the steps but it didn't work. I get an error message saying, "the communication device selected for your connection does not exist. Verify your settings and try reconnecting."
Please help
Thank you

My issue is that after upgrading to 10.10.2, every time I connect my dongle , E303 or others, it eats up my gigabites with a great velocity. In about 10 seconds I lose 1 gigabite. If I don't disconnect it, I have to go and recharge the dongle. Please help me solve this issue. thank you.

Check if any auto update is enabled. Also check Adobe reader updates, bittorrent or utorrent apps is running or not.
Open terminal and type the following command. It will show which program using internet on your Mac.
lsof -P -i -n | cut -f 1 -d " " | uniq

I have 10.10.3 OS and i unable to get the options which is shown above for installation of MF667 ZTE usb stick, if any one knows how to install, pl let me know.

Great manual, thanks!
For me in step 5 I had to fill the APN field.
I searched the net with "APN Telenor" (Telenor is my mobile phone provider in Hungary).
I found that the right APN is "online" for Telenor.
I typed that in, and now it works fine for Huawei e303.
Thank you.

Some 3G moderm will cannot fix follow above. You need uninstall all device.
Find & download kext from google
Then, browse to your usd disk drive > right click open content of your drive.pgk >…find filename.kext
Drap&drop this file to kext loader tab > load kext button.
Wait a few second
Now, go to system preferences> network> + button. You can see 3-4 menu of modem 3g. Select your interface
This fix approve for 10.10.x & 10.11

Hello there,
Could please give me some more specific way to fix this problem. I've tried kext but still couldn't find my service provider interface. Thank You.

i downloaded the OS X El Capitan and now my 8ta dongle refuses to work. When i try to connect it keeps displaying The device has been disconnected or is unavailable. i used the Dongle on another computer and it works. please help.

I went onto the link and did the download, but on the final step of installation, it says "Installer cannot install the software because there is no software found to install".

For El Capitan, the old method is not working any more.
You need to download a new driver for the modem, as El Capitan does not support it by default.
Search for the driver on the webpage of your phone company, they should provide you the driver if they supplied you with the modem.
My telehone company provided the drivers for their modems on this page, but I think this will not work with your device, just FYI:

My MacBook Pro can't read Huawei Modem after installing El Capitan.
How can i solve that?
Please It can't connect and can't read.

My 3G wireless modem for broad band internet
