So, I've actually checked my jamb utme resit results on my phone before, and it's honestly super easy. All you really need is a phone with some airtime (like at least ₦50) and the same number you used to register for JAMB. What I did was send "UTME RESULT" as a text (in all caps) to either 55019 or 66019. It doesn't matter if it's Android or iPhone, as long as you can text.

Once you send it, you usually get a reply within a couple of minutes either with your result or if there's some kind of problem, like you used the wrong phone number or your result isn’t ready. If you want to see your full result slip, you can go on the JAMB eFacility portal online, but that one takes a bit more effort since you’ll need your email and password.

For just seeing your score, the text method is way easier and way faster. Basically, don’t stress about downloading any app or anything like that. I’d just make sure you have enough airtime so the message actually goes through. That’s what worked for me, and my cousin too!
