Moving back Jazz GPRS to PTCL Vfone Wireless Phone for Interent

I was using internet through Mobilink Jazz Daily GPRS Bundle since six months. Mobilink called the bundle as "unlimited" daily. But infact, it is limited to 50MB only, which they wrongly advertising. When I used their GPRS, after end of day they blocked my GPRS without any indication SMS. So I decide to move from Mobilink Jazz GPRS to PTCL Vfone (Wireless Phone) for stable internet which is working well with no hassle.
