Dear All
I'm from Cambodia. I just buy OPPO R3 from China. But when i put SIM Card it show only 2G. I try to other SIM Card and other Company but it is the same.
Now needs help from all of you .
Sorry for my bad English
Here is Spec
NETWORK Technology GSM / LTE
2G bands GSM 850 / 900 / 1800 / 1900
3G bands TD-SCDMA 1880-1920/ 2010-2025
4G bands TD-LTE 1880-1920/ 2300-2400/ 2570-2620
Sound like you got the GSM/TD-SCDMA only version of the R3. If so, it will only give 3G service in mainland China with China Mobile, anywhere else it's 2G GSM/EDGE only. Nothing you can do about it, apart from possibly trying to return it.
Can you confirm what model number you've got? The R7005 is the WCDMA version, and that one should give 3G service in Cambodia.
Yes My phone OPPO R7007 China version.Sound like you got the GSM/TD-SCDMA only version of the R3. If so, it will only give 3G service in mainland China with China Mobile, anywhere else it's 2G GSM/EDGE only. Nothing you can do about it, apart from possibly trying to return it.

It is mean my Phone can't have 3G in my Country isn't it?Sound like you got the GSM/TD-SCDMA only version of the R3. If so, it will only give 3G service in mainland China with China Mobile, anywhere else it's 2G GSM/EDGE only. Nothing you can do about it, apart from possibly trying to return it.

Doesn't have any method fix? if so i will take it back to the seller.Yup, it means that. The R7007 won't get 3G anywhere, except China with China Mobile.
FYI any Oppo model number ending in "7", denotes it's a TD-SCDMA version for China only.
Yes thank you so much for your help!!!No fix. Only thing can do is to return it. The R7005 veriant of the R3 will give 3G service in Cambodia. However I'm sure non of them have Google services, as the R3 was only ever officially sold in China AFAIK. There's the new R5 you could have a look at. There's a proper international version of that, with Google.
R3 is getting on a bit now. And the R7007 version that's still definitely TD-SCDMA China Mobile only. I agree with @Hadron, any attempt to flash an international R3 ROM will almost certainly end in failure. If you got nothing to lose and an R3 isn't worth much, go ahead and try it. You might just be very lucky.
Later Oppo devices like R7 etc, PRC versions will work internationally no problem, apart from the lack of Google.
EDIT:
I believe TD-SCDMA was basically invented by China Mobile, so that they and manufacturers wouldn't have to pay 3G WCDMA/UMTS foreign patent licensing fees. And TD-SCDMA only phones like the Oppo R3 (R7007 version) that could only really be used with China Mobile, were actually cheaper than their unrestricted counterparts.
