The fastest way I've checked my utme jamb result was literally just with my phone. You don't even need the internet. You just open your texting app, type RESULT and then your JAMB registration number (like RESULT 12345678AB), and send it to 55019 or 66019. I tried this for my friend last year and she got her scores almost instantly. You do need some airtime though, so make sure you have at least N50 or so, because it isn't free.

There's also the online method. You just get on the JAMB eFacility portal, log in with your registration details, and click to check your result. But for everyone around me, using the SMS thing on your phone is way easier, especially if you don't wanna stress about finding WiFi or dealing with slow websites. I even did it on my mom's old Nokia. It totally works!
