Help Foreign SIM and Hangouts Dialer/GV

Hey everyone,

So I travel a decent amount and have a wallet of SIM cards for the countries I visit. I really wanted to use my Google Voice number to make and receive US calls, so I set up an OpenVPN that routes all my data back to the USA and tested it extensively in the USA and it worked fine.

Unfortunately, I found as soon as I got overseas and inserted my foreign SIM card, I was getting some weird behavior from the Hangouts Dialer - numbers that I had called in the States were all of the sudden either saying "The number you have dialed is incorrect" or would sometimes ring a total stranger in another country. I believe what may be happening is that the new SIM is transparently prepending the country code or something into the dialer, but am not 100% certain. All I know is that on Wifi in my overseas hotel, with the SIM inserted I get the above weird behavior, but removing the SIM or inserting a US SIM (even if I'm not on a cellular network) fixes the issue.

Does anyone have any suggestions on how to beat this issue? It would be a major bummer if I had to port my number to Ooma or couldn't otherwise use Google Voice/Hangouts Dialer.

Thanks in advance for your response!
 
An American expat friend of mine tried to use GV in China. Had problems with it, think phone had a China Mobile SIM, possibly because it was choking on the +86 prefix, just a guess. He was using a US VPN, because Google is blocked otherwise. He subscribed to MagicJack in the end, that works no problem and uses their app, because he wanted to retain and use a US number even while overseas. There's also things like Skype In/Out and Vonage, sure they both work no problems intermationally, and don't care about a particular country, carrier or SIM.
