I want to swap from China Mobile to Smartone, and move my number.
Reading my current contract (which i think has expired, though it's really not at all clear...), it says I have to give 30 days notice in writing to terminate, but doesn't say where i need to write.
In the UK it's very simple. You call them up, tell them you're leaving and want to port your number, they give you a code which you give to your new provider, then a few days later it's moved across.
How does the process work here?
