BT have managed to send me 4 BT dongles, I only need two. My option 3 (with inclusive mobile braodband) ran out and I was invited to re-new but was told it no longer included free mobile broadband so I was asked to sign up for a new contract so they sent me some new dongles. Now I have to work out how to return the two I don't want without being charged a cancellation fee.
What is the difference between the three different dongles I have now in my possession, I have a ZTE MF636 and MTE MF631 & HUA E170
If I have a choice which should I return?
