1 and 3 drain the phone’s battery really fast, 2 a bit slower, but still. Connecting straight from V would mean instand connection and almost unnoticeable battery tap, because the amount of energy that an LTE connection uses is tiny compared to V’s power consumption and huge compared to that of a phone.
That is very inconvenient. V is a tablet, it’s designed to be used in hands, on a lap, on a desk - everywhere. If you stick in a wire leading to your phone, the only comfortable way to use it would be on a desk. Otherwise it would get in the way too much.
That “someone” can feel free to buy the non-LTE version. But “someone else” might prefer to get an internet-only SIM card for 2€/month.
Why? Leave the phone alone. I don’t want to have a cable sticking out all the time, and some extra device (phone) that prevents me from using my tablet comfortably. I’ve had enough pain booting my Acer tablet from external HDD because the SSD was too small.
Speak for yourself please
Calling functionality is not implemented in V and likely will never be. We’re talking about internet only. You can still receive calls on your phone. By the way, there are only a few operators worldwide that carry calls over LTE. Calls are usually carried over 2G, because that’s enough for hearing clear voice and offloads most traffic onto old infrastructure that would otherwise be useless.
The price difference would only affect the LTE model. Other models’ prices wouldn’t change. At least that’s what’s left in my memory from someone from Eve talking about it.
