LG G3 D850 3G wont work outside USA

I used to have D850 G3 in past and never had this issue. Yesterday got this New G3 D850 AT&T. My mobile signals disappears as soon as I enable WCDMA or WCDMA/LTE. Works fine on 2G though. Not a problem with my network as 3G is working fine on other devices. APN is correctly entered as well. I have tried enabling different network modes rather than GSM from hidden service menu 3845#*850# but same result. What might possibly be the issue?

Brand new device? Locked to the ATT network.

No it wasnt brand new and if its locked to AT&T then it shouldn't work on other carriers outside the USA but like I said, it is working fine on 2G networks

Which version is the phone? It doesn't sound like its an AT&T version.

Did you get a new SIM card?
Was the phone purchased outside of AT&T as an unlocked phone?
(A locked phone will work outside USA, at higher cost)

Was your previous phone an AT&T phone?

Yes it was and never had this problem. What's confusing me is that when I go into hidden service menu via 3845#*850#, I dont see any RAT selection menu in LTE (to change Network Modes like WCDMA, LTE etc). I just cant see any network modes options.

ATT doesn't use 1700Mhz, hence it is not built with D850

GSM 850/900/1800/1900 MHz, UMTS 850/1900/2100, LTE Bands 2/4/5/17/29, Roaming 1/3/7, and CA*

Service provider you are using may be using that frequency.

I purchased a brand new unlocked  AT&T D850 outside US and use it in Canada (TELUS). But except getting FIDO GSM 2G netowork I cannot get any TELUS 3G and 4G netowrk. All TELUS 3G and 4G networks are covered by D850. Even I enter the IMEA # in TELUS netowrk and it responds no issue. There is no RAT selection in hidden menu and Mobile Network menu. Any thoughts please?

return it....

 

ATT removes those menus.  Also you wont get updates to the os since its not being used on the ATT network.

Few weeks back i came from US and i found that i could not use my local 4G LTE SIM cards. I tried many solutions to enable LTE networks. By default Verizon carrier might hidden this in my plan. The solutions i read nothing helpful luckily this information helped me so much to enable LTE on my LG G3 model http://www.digitdirect.in/2016/09/how-to-enable-4g-lte-on-lg-g3.html now i am enjoying 4G speed still looking for solution to enable VoLTE for best calling at cheaper rate. Hope you also find useful..... )
