I'll be in the Philippines for two weeks in July. Can I use the Sonic Mobile Communicator while there? Will it cost me more money? I have business voice. Thank you.
My experience is a residential account.
Sonic will not charge you for using it from anywhere.
You can use it to place calls and it will show as the call is placed from your house.
You can use it to take calls as if you were home.
If sonic charges you to call the Philippines from home, then they will charge you too.
The caveat is: only if it works: if the connection is good enough in terms of bandwidth, latency, packet loss, jitter etc (basically MOS)
The sonic voice client does not let you configure much.
I have used it with variable success from France over fiber and over 4G, from the US over satellite connection. It rings ok but the voice quality varies.
