I have tried your list of faq. I used the online update method. I received a message with the code 8326 for my moto g phone ending in 8326. When I used the dropdown menu to open and install the new settings a requester box asked me for the code. I entered it but got the error message 'code not authorised'. I am in Florence Italy without a phone or data I can use. What do you suggest
I'm sorry to hear that your roaming service isn't working. If the settings code isn't working on your phone, then you can manually set your APN settings instead. Just go to the link that Aimie provided on her post and scroll down to the APN settings, which are listed. On your phone, go into Settings > Networks or Mobile Networks > Access Point Names.
If you are still having an issue with this, please send me a private message by clicking this link: PM me here and provide the following details:
