Howzit guys,

I brought a HTC Aria in the USA on AT&T network. I came back to SA and rooted my phone put Android v2.2 on (phone came with v2.1) thinking that would unlock the phone, but it didn't. I ended up looking on the net for a website that I could get an unlock code for my phone. Long story short, I found one, paid for it and it worked. I'm using the phone on Vodacom no matter what I do I can't get 3G or HSDPA to work, only GPRS. HSDPA and 3G work fine in the states.

After doing some research I noticed that in the Mobile Network settings on the phone there is 3 options under Network Mode:

1. WCDMA only
2. GSM only
3.GSM / WCDMA auto

Now from what I've seen I need to use WCDMA to get the 3G / HSDPA to work, but when I select option 1. I don't get any signal and then phone eventually switches to GSM automatically. I was at work on the weekend helping a customer with her laptop and she had a 8•ta 3G modem, and 8•ta 3G modems are currently running off of MTN's network I was told this by an 8•ta technician and I noticed when connecting the modem it said something regarding WCDMA.

So now my question, if I change to MTN do you think I will be able to use 3G / HSDPA on my phone?

Any info regarding this will be greatly appreciated.

Thanks :D
 
The US does not operate on the 2100mhz band for 3G. Therefore your 3G will not work in that phone. The manufacturers might set up the phone specific to a countries crarriers request to use their regions frequency bands. This is what I am suspecting.
Normal 2G will work as it has all the bands enabled.
 
Ya the phone I brought was exclusive to AT&T so I was thinking along the same lines. I didn't worry about the 3G cause I previously researched this and didn't find much. I've been using the phone for a long time without 3G, but then on the weekend I noticed on the 8•ta modem something says WCDMA and just thought I'd ask :P

8ta also operates on the 2100mhz band. The only operator in SA that officially uses 900mhz for 3G is Cell C...but even Cell C wont work I think as your phone wont support it. If your phone comes from AT&T then it will only support the 850/1900 bands for 3G. I could be wrong..but this is how I understand it.
