Probably the most reliable way to reach me is through WeChat. I hope we can be WeChat friends. WeChat is free. My WeChat ID is kahaluu.
The reason I suggest WeChat is that because sometimes I don’t have my phone, its normal SIM, and/or T-Mobile/Google/Skype lacks service in the area that I’m visiting.
So although you may have established a non-WeChat mode of connecting with me. Please feel free to use WeChat in case I haven’t responded timely. Otherwise you’re also welcome to just continue using the mode you find most convenient in contacting me. Thanks!
