Hi Hotcopper12,
Mobile number portability is an excellent feature but I understand Tesco is UK based. How would Freshtel go about an Australian mobile number portability.
In regards to MNF, they don't have mobile number portability. BUT MNF do support business number portability for their Virtual PBX.
