Ok, so in my house, I always get poor reception, using 3g or GSM. I usually get about 2 bars. Anyways, when I have 3g enabled, even when I have 2 bars of service, I can't send an SMS for the life of me! I can with GSM enabled instead though, also with 2 bars.
Why is this!!
This happens on multiple ROMs too, so I highly doubt it's a ROM problem.
Any more information would be awesome!
