I Need Advice on a New Cell Phone

[Leith]

I have a Samsung and my carrier is T-Mobile. I hate them both more and more with each passing day.

The phone battery lasts 6 hours if I'm lucky. That's with no apps or anything else running.

The last straw: several people have tried to call me in the past 2 days and not a single one shows up on the call log. I checked voicemail and there were NINE messages without a single call in the log. A good friend had left 3 of them. Her husband died recently died and she has not been taking it well. I felt awful that I did not know she had been trying to reach me.

I need a new cell phone and a new carrier. All I need is to be able to make and get calls, text messaging, though a camera would be nice (but not absolutely necessary).

Thanks in advance for your suggestions.
