Morning.. This is a fresh imei with which you can get upto 300MB if tweaked correctly. Though it works well with new SIM card(one you haven’t tweak any imei with it before..). Without too much noise, below is the imei to be used:

35842906480 (add any 3 digits and analyze using imei analyser)

after the tweaking, then send mifi to 131.. You can try using sms bomber to see weather it could be accumulated..
