I have local cell-phone numbers for each city I live in, but they are only active when I'm there.  

Even then, I don't pick up all voice calls and respond to all SMS messages.  

The best ways to reach me (both voice and text) - are via Facebook Messenger and WhatsApp (see next section)...

Instant Messaging & Calls

The two channels I use for both Instant Messaging and Calls are:

Facebook Messenger
