I am currently using a similer answer but on 3 unlimited
The first problem is data usage. When we used a mifi device with 15gb allowance it was soon used up just on domestic stuff.
The second is reliability. When its working its good but speeds can suddenly drop. I could not part with the landline 2.5mb connection, its slow but reliable.
Advertised coverage and real coverage are very different. Our coverage is not that good, no signal inside and maybe outside but the maps suggest quite reasoble coverage. I used a couple of apps on my phone, GSM Signal & Open signal to find the best locations. Then put on antenna up based on that information. It was not in the obvious place. It turns out we get no signal from the closest mast and in my efforts to get the best signal from that mast I been putting the house between the devicet and where the signal was coming from.
When of working I have used a mifi device constantly connected to multiple devices for over a week, I just leave it constantly plugged in. Now for the unlimited on 3 I have had the phone constantly running as an hot spot for nearly a month.
Just to give you an idea of reliablity. The system as been working steadly 6mb download all morning When I clicked to send this it timed out. Trying again now
Its timed out again. This is typicalof the problems. 2 of us have been doing office type work all morning, sending emails, ordering stock, checking the football news, then suddenly I can not post on a forum. Last try with the mobile then will use the landline.
