I'm not 100% sure, but IIRC, with latest ROM, the SIM you set as "mobile data" use 2/3/4G networks, while the one not used as data SIM will use 2G and 3G networks. Older versions of UMi Super roms only supported 2G on the non data SIM, and some providers (at least in my region) don't have 2G at all (like one of mine...)
I don't think the different SIM slots make any difference - It's which SIM is set as data that matters. |
