Could anyone suggest what I should use for phone service while in SE Asia? Someone suggested Unicom for China. Is there any service that would be good in all countries? I'm not very knowledgeable when it comes to phones. I upgraded from my rotary dial to a smart phone though. I have a Samsung Galaxy.
I'm not a heavy phone user. My communication home is with Skype. If WIFI isn't available I would use my phone to access forums and Skype. When I rode through Russia several years ago, I bought a modem? and a simm card for my tablet. I think I don't need a modem now that I have a smart phone.
