Why multi-network matters in CF15
Coverage in CF15 varies by network — one provider might be excellent on one street and patchy on the next. Single-network providers (giffgaff, VOXI, SMARTY, Tesco Mobile, BT Mobile) tie you to one carrier. With Fuse the eSIM holds profiles for all four UK networks and switches automatically based on signal strength.
