Riders can travel to Tijuana, Mexico, from San Diego on a smooth and hassle-free ride, Uber wrote on its website. A black car can pick you up in ~2 minutes. An UberXL car can pick you up in about 3 minutes. No, they can take you to the border but they can't cross because Uber in Mexico is a completely different system.
I would bring pesos since that's how I pay my ubers in tj. And try not to order an Uber near a taxi service because they will screw you and Uber. I would like to walk a little. The reason is because the taxi service in Mexico hates Uber with such a strong passion that people have been beaten for just using it.
If you're traveling to Tijuana from outside the San Diego area, you can take a Greyhound bus to the border. If you want to take an Uber from downtown San Diego to downtown Tijuana, you'll need to request a transfer to the border, cross the border on foot, and then request another trip in Tijuana after crossing. But as I mentioned before, if you go to your Uber or Lyft app right now, you can see the prices for how much it will cost from San Diego Airport.
