Compare HCL ME Y1 and HCL ME U1?

I am looking to buy a tablet under budget 7,000 and found two interesting tablets by one of the most premium buyer HCL labelled HCL ME Y1 and HCL ME U1. I want anyone here to compare these two tablets and tell me which one to go for.

thanks in advance.

HI anuj, a bit more higher specifications but the major difference comes under SIM support facility.
