Samsung Galaxy S3 on Straight Talk
This is a very very much talked about topic. But mine is entirely different case.
I have Verizon SGS3. But it's unlocked and can work on the AT&T 4G HSPA Frequency.
Bought a Light Blue BYOP SIM. Cut it into Micro SIM Size and put in SGS3.
Now, I browse different forums and try to enter APN SETTINGS.
But cannot enter new APN Settings in menu, more settings, Mobile Networks, APN Settings. I don't know why.
Next I bought APN Manager pro. Still no luck.
Then downloaded HiAPN.
Then I'm able to enter only first field.
Now I'm getting EDGE speeds or 2G speeds.
How can I get 4G speeds???
