I am away in my touring caravan over easter and want to watch the local football derby on sky go on my macbook. I will literally be in the middle of a field so everything is ran from batteries and internet via the mobile networks. I have an iPhone 6+ on vodafone and a iPad mini2 on EE, both allow tethering. I have looked on each carrier's coverage website and both have weak 3G. Is there anyway I can tether from both devices at once to improve my connection speed to a level where I can stream the match. I also have a Huawei E5776 mobile hotspot with an external antenna that I use the EE sim from my iPad in, I can connect that to the mac via wifi or cable if that would make it possible to split between that and the iPhone?
