I'm using e5180 EE version as well, but with the telephone jack version. Never know there are some many versions for e5180. I bought it from Qoo10 and then only realised can get much cheaper from andrewsestore Anyway, I'm using bb100, so never try to connect phone into it.

I'm tempting to get i150, but the speed at my area hold me back. My area speed quite slow and not stable even can get 2-3 bars LTE signal, normal day can reach up to 4-5mbps, but sometime dropped to 500kbps Think must be the modem keep switching bands but unfortunately, there is no way to lock the band on this modem.
