I love reading people's remarks about how you can't do this and you can't do that. I've been using a tablet for Uber for 3 months. Main reason is they don't have any business snooping around in my personal phone, but I like having a bigger map display as well. I don't have their app installed on my personal phone, but I use the messaging and texting features of my personal phone to alert riders. If you want voice phone and texting on your tablet, get a Google voice account and phone number and run that app, then give the Google voice number to Uber. Don't rely on wifi, get a regular 4G tablet from one of the carriers. I have mine with T-Mobile and get 5 gigs of data for $30 per month, I believe. Make sure you get one with more than 2 gigs of RAM. I've noticed the Uber app can bog the tablet down after 3 or 4 rides, forcing a restart on the tablet.
