Question: Any good dual SIM phones out there?

I was wondering if anyone might be able to help me out with a quick question...
I have a dual-SIM phone that I picked up from Verizon, and while my primary SIM is through them, I recently popped an AT&T micro-SIM into the second slot. I've got some data left on the AT&T plan that I’m really trying to use up, but for some reason, I just can't seem to get an internet connection through that line... even though I've made sure the cellular data settings are switched over correctly, nothing seems to be working

You might want to double-check first if the phone is actually unlocked and compatible with AT&T. Basically, just make sure it’s fully unlocked for any carrier out there...

I can also make calls and send texts using my AT&T card

Probably doesn't even have the AT&T APN settings entered

It feels like I'm unable to get anything done...

Hey, you might want to give AT&T a call—just ask them to text you the APN settings for your data...

Usually, you can't run both data connections at the exact same time. You'll need to jump into your settings and specify which card you want to use for your data connection.
