How do I unlock my phone? (update)

[AC Question]

Here are the details:

1.) I forgot my pattern and I have no idea on remembering it.

2.)I can't connect my phone in my computer via USB cable because I can't enable mass storage. It is only charging whenever I connect it.

3.) The option "Forgot Password". I'm not sure if I connected my phone etc.. PLUS!!! I can't turn on wifi...PLUS!! My data network can only access facebook because it is super slow.

4.)I own an china phone(good). Whenever I enter factory mode it has chinese font, so I searched the internet and found a result but the problem is, my phone don't have that specific option to hard reset it.

Any other methods mates?

Update 1

Yes I tried google android device manager but the problem is my phone is not connected on the wifi so it could be detected by google android device manager....

If the phone is connected to 3G or 4G (or even 2G data), Android Device manager should work.
