You don’t need to buy a Webe compatible phone in order to use Webe data. On any phone, just configure the APN settings to the following and you are good to go.
Unifi APN Settings (webe has been rebranded to UniFi on 16 September 2017)
apn: unifi apn
apn: webe apn
You can leave others as default/blank and it should work.
