I live in a rural area and my internet is terrible. As the signal comes and goes, between 4g and no signal at all. Im on a pay monthly contract. My quedtion, does the pocket hotspot have any kind of built in aerial, that would increase the signal strenght ? As i have tried using my phone, which is a samsung galaxy A9. But has not really made things any better. So i wondered if the pocket hotspot would be a better option ?. Also if i ordered, does it have a cooling off process, so i could try, if no better, could return, before tied into the contract. Any help is much appreciated.
