Zoom 4506 / Huawie E3131

I have recently purchased a T Mobile Huawie E3131 dongle to use in my Zoom 4506 router.

I can use the router with various other dongles on O2, GiffGaff, vodafone, three.  In the area I am currently visiting the signal from T-Mobile is much faster for mobile broardband with other networks only providing a slow speed and I know TMobile will give me 1mb+

I have tried the following

APN
general.t-mobile.uk

Dial
Nothing
*99#

Pin
Nothing
(pin on the sim packet)

User
Nothing
user

Password
Nothing
pass
Tm

I just can't get it to connect!
Pleae help

I thought I would reply with some findings.

Most importantly it appears the E3131 will not currently work with the Zoom 4506, I have now unlocked a E173 that did work and was on O2/GiffGaff and with the t-mobile SIM it will connect without problems.

I believe that the settings are
APN general.t-mobile.uk
User t-mobile
Password pw (this is not 100% sure)

However with the E173 I have found that I do not need to enter any of the above (Like zoom Technical support said I would need to) it will connect with nothing in the basic settings page on the zoom.
