correct me if I am wrong : I have vodafone galaxy s2 I9100T version ... and yesterday I moved to Optus... so the phone still has Vodafone Modem... but I am still getting H+
so from the above article & following article,
Telstra & Vodafone = 850mhz 3G network = I9100T version
& Optus = 900 mhz for 3G network = that means my I9100T version should not be working with Optus SIM and should not be showing H+ at all ?
OR maybe right now my phone is using 2100mhz Optus band ???
also, is there any way to check what frequency the phone is working right now?
Yes, I am using Vodafone modem on Optus, works fine... No i haven't tried any other modem.... I was to, but seeing this, I do not see the hassle to try new modem....
p.s. see attachment
P.S. the phone says I9100 because I am using Chainfire's unsecured Kernal, as the phone is rooted, but if I put the original Vodafone ROM in it, it will show I9100T
Changing the kernel shouldn't change the model number though, changing the modem will.
