It's perfectly reliable if you have signal which you'd check before committing if it's for business you won't be going mobile with it so fairly easy to check whether its feasible PAYG would not be the option I would choose for that very reason but there are some good contract deals available and if your link means that much to you it's cheaper than a leased line with SLA

Thats why it's a backup ffs, it's not perfect but it's better than nothing, if you can't understand why someone would pay a small amount of money for a dongle contract for the backup then you obviously have never run your own business.

It's like having contents insurance you still lose everything you had so why bother with it in the first place

3g backup would be like an insurance policy, I really shouldn't feed the troll so I shall stop now suffice to say you are labouring your flawed point, you clearly have no real understanding of the matter

but if they did they'd be the best line cards in the world

who says they replaced anything probably just moved his line and kicked someone else off who may complain less

Thats where being a quality highly trained engineer comes in isn't it?

Yes you can same day appointment or you could go to A+E and be seen inside 3 hours

often nor does BT
