COBA it's a great app, there are many apps out there but mostly for Argentina, Colombia or Brasil, COBA come as a pioneer in Mexican market with a REAL US bank account, It's awesome how simple and easy the process is and i really know COBA will be growing up! Besides the app works very smooth and if you dont want to use or not have your cell phone you can just go the web page and its done!. Congrats COBA!
