I’m going to start off the tips with this little gem:
If you’re bootstrapping it, and you’re on a trip in a different country, NEVER roam with your cell phone. It will always be cheaper to buy a local SIM and pay local rates. And if you find yourself traveling frequently to a certain country, it could even be cheaper to get a SIM with a line (as opposed to a pre-paid SIM) and use that every time you visit that country. Either way, roaming will kill your budget unexpectedly, and is not good for any company that is bootstrapping it.
