Since writing my last preview of MT6592 THL T100 Monkey King 2 / Iron Man, the shops have changed their tune and are now including 850MHz WCDMA / UMTS in the specs of the T100. Some are now even showing 1900MHz WCDMA. The MT6592 Mlais MX69 Pro is showing quad-band WCDMA (850/900/1900/2100) on shop sites and on the Mlais official page as well. Is it too good to be true? A China MTK phone with both of the major American frequencies?

For those who are scratching their heads right now, I’ll explain a bit. The main frequency of AT&T and AT&T MVNOs for 3G/UMTS is 850MHz. They also use 1900MHz in some areas. T-Mobile and T-Mobile MVNOs are mostly on 1900MHz. Phones with 850MHz WCDMA will get 3G service in most areas serviced by AT&T. However there are very few, if any China phones released with 1900MHz WCDMA, so current China phones will receive only 2G service if on T-Mobile lines.

Two of the major MTK6592 phones currently being released, THL T100 Iron Man and Mlais MX69 Pro are showing wide spread signs of having 1900MHz WCDMA as well as 850MHz. Whether it’s actually reality or not is an entirely different matter, and we probably won’t know until Americans have them in their hands and can test them on T-Mobile networks.

For those in Europe / UK or areas with 2100MHz UMTS, you need not fret as nearly all China phones are compatible with 2100MHz WCDMA / UMTS.

There is one thing even for Europe and United Kingdom to keep an eye on regarding China phones – some of them are set to TD-SCDMA for 3G. Phones that are GSM/TD-SCDMA will work on 2G assuming it’s got your frequency (900/1800 for Europe/UK and 850/1900 for Americas), but 3G will only work in China on the proper network with TD-SDCMA phones.

What is the reasoning for China using this special band only for their country? What they’ve done is try and create their own standard so they don’t have to pay licensing fees for foreign technology. However there are some that think the TD-SCDMA is still largely using patented WCDMA technology and they still may end up having to pay the fees.

So I’ve gone beyond the breadth of what I’d meant to discuss. The main thing – I’m excited at even the possibility of MTK China phones having multiple 3G possibilities. That two of the major players are showing signs of widely opening up their phones to the Americas with both 850 and 1900 is great, however we won’t count our Droids before they hatch.

I’ll be keeping a sharp eye on this and will come back with regular updates regarding the situation.
