The A12 has "Dual SIM", ok. But does it also support Dual LTE ? Because after 2G is/will be switched off here in Switzerland, the Dual SIM function would be useless if it works like its predecessors: One SIM slot can be switched to LTE, but then the second SIM slot is necessarily limited to 2G and therefore useless here in Switzerland. So can the A12 really offer true dual LTE, with LTE on both SIM slots?
