Phone under 400$

Get a Nokia 130. see: https://www.gsmarena.com/nokia_130_(2017)-8769.php
Decent first phone, good reviews and available for around $12 so you'll have $388 to spare.

for 400$ you can get an asus rog phone II, i would definitely recommending you to look into that phone. You wont regret.

This is literally the same thing as the one above, just gonna sell out soon so get it fast!

i think for low budget phones, you get lot of stuff by xiaomi, i used one in a while and was very goo for my daily use and i favor miui.

there are a lot of phone under 400$ but it all depends on your country so if could provide this we my pick one for you
