Is there a way to boost the reception of your phone?
If I put my phone in a metal case with long antennas on it would that work?

Cell phones require two way communication to work. Even if you think you’re just receiving data you’re actually transmitting acknowledgements that you successfully received each packet of data. So the first thing you have to do is determine if your “reception” problem is actually a reception problem or a transmission problem.
Better antennas are a good way to boost both. I should note here that antennas don’t actually boost power, either received or transmitted. They have no external power source so they can’t actually amplify total power. What they do is redirect it…they trade power in one direction for power in another direction. Putting a “better” antenna on a device can be done but if the interface isn’t perfectly matched you lose all the benefits by introducing new power losses (to heat and/or signal reflections) at the unmatched interface. With cell phones the manufactured antenna and interface are already matched. Adding a different one would be unlikely to work well.
