Have some questions for to compare service:

Are you overall pleased with their service?

Can you use a 4G cell phone on their system, and does it work well for you. Fast downloads, website browsing? Where (geographically) 4G is not available, does it work well on 3G?

Does your service sometimes either not go through - ie, you have to try again and again (up to (5) times (for me) to download (open) new website pages, when you've stayed on one web page too long?

Thinking of upgrading to a Samsung Galaxy, or perhaps a reconditioned iPhone with my Straight Talk $45/mo plan.
