They are switching off 3G, and your backup link was 3G
Movistar has started switching off 3G in Spain: 14 municipalities in Cádiz and Cantabria, some 250 base stations and around 20,900 radio sites through 2027, with no calendar by locality. Vodafone no longer runs a 3G network, and MasOrange finishes on 31 December 2027. Inside: why this takes away compatibility rather than coverage, the inventory of your own kit that carries a radio, the field in the command that tells you which technology each modem is on, and a drill for switching 3G off yourself before the operator does.
