Yoigo is the fourth mobile phone operator with a network of its own in Spain. They operate a UMTS/3G and 1800 band network, which at their launch in December 2006 had very limited UMTS (3G) coverage even in some of the largest cities. In places where there is no UMTS coverage, Yoigo users switch to national roaming using movistar’s both GSM and 3G networks.
