Some issues

If you want to phone from Mexico while on a vacation, this can do the job. However, dont think the app developers have figured out how to work with Googles 2 step password system. I can no longer log in. As well, clearer instructions are needed on what dialing codes are needed when calling from one country to another - I did it by trial and error. Using Google phone from my laptop is a better, more reliable and user friendly approach.
