Essential to my recent decision to pack it all up and live on the road was the ability to maintain connectivity with friends, family, and work. In the past, I had to give the most lasting hugs I could because leaving the country rendered communication difficult, expensive, or impossible. Luckily, we live in a time where technology is catching up to the way we want to live, and I found a great solution to this problem by switching my number to Google Voice. Now I can send/receive calls and texts (almost) as if I never left. Here are some of the features that have been useful for me as a traveler.
I want access to my real phone number from anywhere in the world.
Here's the challenge. I have a cell number that I've been using for 10 years. I consider this to be my real number, and don't want to update all of my contacts every time I move around. Google Voice largely solves this problem. Upon porting my number, it lives in Googleland and I can seamlessly use my real number anywhere in the world through a computer or phone app via wi-fi.
But what about phone companies?
A key concept is that Google Voice is not a phone company, rather it is a wrapper around cellular service. This is confusing, but cool. When I need cell service in a new place, I pop in a sim card, get a temporary local phone number, and buy a bundle of minutes. The magic of Google Voice is that it takes all of these temporary phone numbers under its umbrella and makes them feel like my real number.
In other words, Google Voice is like a receptionist. When someone calls your number, Google Voice guides them to you, wherever you are, whatever local number you're using. It's beautiful and I'm able to totally avoid cell companies' bulky and overpriced international plans.
Also, thanks to the rise of pay-as-you go plans in the US, I only pay for cell service where I need it rather than paying down a useless 2 year contract while I'm out of the country. Google Voice allows me to seamlessly switch between my various types of short-term cell service.
It's not a perfect solution.
Despite the fun receptionist image, Google Voice does not solve 100% of travel connectivity issues. It doesn't work perfectly when outside of the US and outside of wifi range since Google Voice will not forward calls to my Argentine (for example) cellular service. To get around this I buy a local data package and use Google Voice through the data connection. This has worked reasonably well, though not perfectly.
Another downside is that Google Voice does not do MMS. So, when my sister-in-law sends a cute pic of my new niece, I miss out. This is kind of a bummer, but I try to remind friends and family to send pics via email instead.
Finally, as anyone who has ported a number from one carrier to another knows, this process sometimes takes several days to complete. I was not able to get all calls for a day or two and I couldn't get texts for about a week. So be careful to avoid the porting process during times when communication by cell is absolutely necessary.
