Wasn't sure where to post this, so I just put it here.
I was gifted a fake Galaxy S4 (a 1:1 copy) for Christmas. I was overseas so I could not test whether the SIM card worked. Upon return to Hong Kong where I live, I put my SIM card (my provider is 3 HK) , originally from my (real) Samsung S3 LTE into the fake S4. I managed to get a signal, and I was able to call someone, but my 3G internet does not work. I have tried toggling the GSM and WCDMA settings, and setting different APNs, but to no avail. Anyone know why this could be happening?
I also experienced a similar thing like this when I put the same sim card into an iPhone 4, where I could only call, but not use the internet. Something is telling me it may be that because I use LTE 4G on my SGS3, and because the fake phone does not support 4G it does not work.
I hope someone has had similar issues and is able to find a workaround. My fake S4 is rooted with CWM recovery and has a MTK MT 6589 processor.
