Linux:alykov: I had a problem to connect to the Internet in Italy, but It works now.
you must create a new APN with wapaccess.co.nz to fix that issue.
@alykov You don't need to create a new APN to use data roaming as that APN should be used when in New Zealand the way roaming works you should never have to change any settings / phone setup
I'm in AU at present and I had to change both the internet and MMS APN to get them to work. The default Telecom ones shown above don't work on roaming.
