I recently added a razer phone 1 to my plan and when I was going through the APN settings I ran into an issue. When attempting to set the single APN settings my phone is giving me an error stating "dun" setting is not allowed by network. I cannot save the information in the phone... however... I don't think I need to set this up as my phone auto selected Ting as its network and seems to have full internet connectivity. Should this be ok? or am I going to have an issue with mms or something in the future?
