This is a great budget phone

Excellent budget phone, I am using this with my T mobile monthly service plan.

This is a decent budget phone with plenty of storage

Now, of course a budget phone like this one will have some drawbacks, but I consider them minor.

I did have complications with AT&T regarding SIM card size

So, they should work well with Sprint, T-Mobile and AT&T as well as all of the pre-paid vendors who use their networks (Cricket, Boost, H20, Virgin Mobile, etc)
