i just spoke to one of the 8ta people over the phone and this guy shared some interesting stuff, he told me that i should get a modem from their store an 8ta modem and then i should ask them what modem is better for upload or what ever i want. he says cause there are modems which have been set to go to a certain speed. and that it is best to get a modem whichever service you currently using. for example if you using vodacom, then get a vodacom modem, if you using cell c, then get a cell c modem. thats what he said. i believe him cause i have a K4505-z vodaofone modem, when i use my vodacom sim, i get 2bars in HomeFront playing 32players online and it was running GREAT like there was no lag!. but when i pop in my internet 5 promo 8ta sim into my K4505-z then i get a BIG RED BAR in HomeFront and it LAGS like crazy. oh and you also need a good 3g router that supports the modems. try www.dbg.co.za look for TL-MR3420 3G router, it supports all 8ta modem. this method is best for gamers who play xbox live and PSN.
well maybe later im going to get the E1820 or E173 at 8ta. then il update on that. thanks hope this helps guys.
