Vodafone didn’t release speed or coverage but has something in 15 cities in Spain. The network is Huawei, although for now they are not expanding Huawei in the core network. The available phones are Samsung, LG, and Xiaomi, but not Huawei.
Vodafone has 90 MHz of spectrum at 3.5 GHz, which should deliver customer speeds of 100-500 Mbps. Voda only provides the meaningless comment “up to 1 gigabit.” Coverage is “15 cities” without detail.
Vodafone has also turned on some radios in Italy and will turn on some in England on July 3. I have friends at Voda who are very satisfied by Huawei service and support.
