With the launch of the B7, Bigme is competing with the popular Boox Go Color 7 (which also released their 2nd Gen last week of April 2025). Bigme has really upped the ante on the specs of this one, surpassing the Boox variant in many areas, and it also has two features that the Go Color 7 doesn’t – a rear camera and a nano sim card slot.
This means that should the user desire so, the Bigme B7 can be used as a cellular phone – the only problem is of course its size which makes it more of a tablet than a phone. Check out the specs differences of these two 7″ Kaleido 3 ereaders in the table below-
