Yes it will work WCDMA is just a 3G, but the slot also can connect to 2G networks like GSM/GPRS/EDGE.
If you are going to use it with GSM only sims u shouldn’t even bother about getting the WCDMA OR TDCDMA version. Since either can use GSM on both sim slots. It’s just the 3G that is only enabled on 1 slot, GSM is something “default”.
