So i am using 1 bsnl sim on which i am using 333 plan (3gb each day). No i just bought a new sim few minutes back on which i am going to use unlimited 3g 1099 plan. Now i have a question when i am using 333 plan activated on earlier sim with D-Link dwp157 modem on modem it shows H signal while on my j7 prime its hows h+ signal. Earlier in march i used same sim with 1099 dlink dwp 157 shows h+ signal but since june its showing h signal and in march i was using windows 8.1 now i am using windows 10. Thats the reason i bought new sim.
