Yeah same here
Does it mean that we need to wait for the non China ROM??
Anyone has found the link to it already??
Thanks.
No sim lock, but the phone uses a specific version of the ruim card. Please, who knows, tell me, what's it! May be someone know where I can find the "right" ruim card, may be link..
I found the answer how to unlock: need change the MNC and MCC of your carrier to China Telecom`s - 46003 and write it to ruim card. voice and 3G data works perfect:good:

Hello <
I guess you are using a rom without Gapps ... to solve this problem you can use a custom rom like Tomato roms which is besed on touchwize (Samsung official rom) just google it ( tomato rom) the latest version is 5.0 if i'm not mistaken ... you have to make sure to choose rom+gapps during the installation steps (its in chinese language ) ...
good luck

Defy mini xt320 3G connectivity issues

Hello,
I bought an Defy Mini XT320 on Spain and brought it to Brazil, but here the 3G or 2G doesn't work at all. Anyone know a way to fix this? Maybe flashing another ROM, maybe a ROM from Brazil?
Thank you for the help.

Maybe you should change your APN.

It worked, at least the 2G network is working. Maybe 3G can't work because of the different frequencies used by Spain and Brazil. Need more testing to have sure.
Thank you for the help!

couple of pertinent questions that will help us help you:
Phone Variant:
Carrier:
MVNO:
Firmware/software version:
One plus a6013 version d'oxygenos 9.0.13
You need to verify that your phone and carrier are 100% compatible. They should be, but worth to verify bands.
