Why won't my Q10 sim give Internet/blackberry services on my 9790?

Hi there, Ive been using blackberry for years and recently upgraded to a q10, but I don't like it and want to put the sim back in to my old 9790. I know the q10 uses a micro sim and I can make it fit the 9790 no problem, but it only lets me use texts and phone calls and not any internet or blackberry services despite me having unlimited internet on my sim. I heard that this is because the q10 doesn't need a blackberry bolt on plan, whereas the 9790 still does, but does anyone know if there is a way to just get the Internet up and running again without the bolt on plan? Thanks

Q10 uses a standard data plan. 9790 requires a special BIS plan.
