I had an iPad mini 4 cellular but never activated cellular data. I always had maps load wherever I went. I returned it for an iPad Pro 9.7 cellular and also did not activate a cellular plan. My maps never load in DGI. The only way to get a map to load is to connect to my cell phone until the map loads. I swear I did not have to do this with my mini. Should my maps load if I don't have a cellular plan?
