I have a Samsung Galaxy S5 SM-G900F which doesn't support the 4G LTE 700Mhz band.  I don't really need 4G speeds anyway.

I was wanting to know if Sparc's 3G network is all HSPA+ or are some areas of the country still at slower standard 3G speeds?  HSPA+ is plenty adequate for my requirements.

Also would I be correct that all areas with 4G 700 coverage will also have HSPA+ coverage?  ie.  There are no new sites that Sparc have decided to only install 4G LTE 700?  I rely on phone data a lot when on the road.

I couldn't find this information online anywhere.

Cheers.
