I use a phone almost only as a portable hotspot. So the smaller size is handier, but if the larger phone gives even a 3% better connection or reach or quality hotspot, I would bother with the newer, more expensive phone in a heartbeat. Does anyone think (or know) that they might get a better reach with a 6S Plus than a 5S? Same plans, same areas, etc. Would the larger phone have a better powered antenna (or whatever) or even an iPad might give better/worse hotspot connections/service? I couldn't find anything on the subject, if anyone has some technical knowledge or experience, it would be very interesting. Thanks!
