brought 1 unit b310-22d help friends.... haha... got a hand to test agains.

RSRP, SINR abit higher than b618 only. but speed wise can conclude..

b310 avg test max only see around 20+mbps. same spot.

b618 avg test normally i use min 40mbps+

testing same band b3 only...

can conclude b618 is double b310 speed   

when in 4G+ location should be a huge gap different in performance...   

moday i test again in office 4G+ location.

later attach screen shot.

[attachmentid=10268184]

in term of stability vs the reading on hmanager.
1. b618 very stable, value does change much/ can see stable reading.
2. b310 very jumpy...value change in secs.

RSRP different a little bit only, SINR a bit higher different...

choose modem wisely for 150i       

U wont get infinite account for the other sims.. no quota sharing..

i80 also worth it if u able to get discount

Actually i have no choice but to use phone as hotspot permanently because i need to make calls with the number as well.. or is there any other solution? i am very open to suggestion..
