The specs that I have seen for the E585 say that it doesn't support UMTS 900MHz (http://www.modem3g.com/e585-p-56.html?gclid=CILblfDLgaUCFZVc2godLT-HPQ)
Please let us know once you have tested it with a Cell C 3G SIM.
Agreed, will have to try. Might try it this weekend. Gonna get on in EL and will test.
I will say this, the link you gave doesnt seem to have as much comprehensive info as the link I found, that makes me wonder if they are just being slack on the 3g site. The only way we can know for sure is by finding it on the actual Huawei site or something official.
