If 2 sims are being used at single IMEI it can be blocked by PTA dont risk it.
ok so here is my case//
i got a jazz 4g donggle device it gave me 2 mbp/s in starting days and at day 10 it came down to 6 kpbs. so i complained alot and they did nothing ... one day i learned the device can b unlocked for multiple ordinary sims .. so i unlocked it ...
after alot of days i came to know that with the unlocked device u cant use ordinary jazz sim and all other network sims... so i decided i need jazz one too ... in this process a guy changed my imei ..... i saved the original imei of the device and kept it...
with the changed imei from the agent , it gave me very less speed.
so i have got a spare mobile its useless and crap j-7 or something , i copied one slot imei from it , as no body uses it , and transferred it into the device..
so now 2 things happened .. one is device speed is increased,,
and two , i have a 10 gb per week bundle activated , Its DATA is not reducing its kind of unlimited now...
i was worried how cant the data be consuming while i am downloading something..
i had put a telenor sim into it , its speed was less like 250 kbps , the towers are very far away ... and to my amazement without any bundle being activated and just 3 rs in the sim .. i downloaded some files and watched some videoes on youtube
how could i be free browsing and downloading ?
