I have just purchased an Unlimited Data Max SIM on contract to work with my Draytek Vigor 2866lac 4G LTE router.
Whilst the SIM is apparently recognised by the device (ie. ICCID is apparently valid), the device fails to establish a connection to the Vodafone network. I'm using the following connection details:APN Name: wap.vodafone.co.uk
Username : wap
I've also tried internet/web/web, but this doesn't seem to make any difference.
The device works flawlessly with an EE SIM.
Does anyone have any suggestions as to how I can get over this ?
Many thanks in advance
