I just bought a new Moto G7 Fast and swapped in my old sim card and the data speeds are absolutely awful if I'm using my mobile network. This phone flies one my Wi-Fi with download speeds of over 130mb consistently but if I'm off Wi-Fi my speeds drop to in the 1-2mb down and up both. I have only done the basic system updates, reset the networks, and I'm not sure what to try next. I just want to get usable speeds out of this phone. My old Moto E5 Go was substantially faster than this one is and it was a $30 phone...What should I try to remedy this?
