gl-E750 multi net sim

Hi,

I have recently bought a GL-e750 with a sim card that supports using multiple network providers ee, 3 and vodafone.

I connected the sim and worked fine on the 3 network and then i got the network switched to ee, and now its stopped working. Its showing as connected in the admin page and i have an external IP but any connected devices cant browse the web.

Are multi net sim cards supported?
Has anyone any guidance for me please?

Thanks

Try manual set up and choose ttyUSB3 as device.

Hi i tried this but didnt work

Also set the ttl to 65?
