Dual SIM: Is There A Difference Between SIM1 and SIM2 Slot?Does this apply to Samsung A71 mobile,I have been using sim2, would I get better signal and mobile data on sim 1?

Sim 1 allows full data, sim2 only calls and messages

There is no difference, you can select from settings what each sim card does. But you are only using one so don't worry about it.

Yeah, it's pretty handy having a 2nd SIM slot. The 2nd slot is handy for a work number... Or for other intentions... Lol.
