To expand upon my prior post, I wish that we still had the "Roaming Only" setting. Sprint was unprecedented in offering the setting, and it was useful in certain unusual situations. However, it required responsible use.
Sprint still has the broadest and deepest roaming agreements of any domestic operator. In many markets, VZW, AT&T, and T-Mobile provide no roaming fallback, but Sprint provides one or even two roaming fallback networks per market in the PRL. We can only hope that continues.
