I bought a phone for my mother who just wants to be able to text her kids. I bought a Lumia 530 and $25/m plan with a few calling minutes and texting included. I was told this would work fine and could turn the data off. When she said her picture messaging wouldn't work I was instructed to turn the data on but leave 'background data access to be restricted'. I'm now consistantly getting $7.50 charges for data usage of 1MB. The rep told me this wasn't fixable and that all phones do this. Does that mean it's impossible to use picture messaging on my plan without incurring data charges?
