how to unlock a wifi mini box so you can take in abroad and use there sim cards

Where did you yourself get this device itself originally? Did you buy it yourself new direct from EE or from a 3rd-party reseller or is it 2nd-hand? The unlocking process & costs are different. Was it originally on contract or PAYG? How old is it? EE won't unlock contract devices less than 6 months old.

I purchased it from EE and it is over 6 months old I have recieved a
unlocking code but when I try to log onto hppt//.192.169.1.1 we says it
will take you to a unlocking box where you enter the code but takes you
back to the we web pg .this is where I am stuck . And do I go onto another
wifi devise to log into the hppt web page ?

What is this "we web pg" it takes you to? Post an image of it.

Have you inserted another network's SIM? Which 1?
