SureSignal - does it work for voice and SMS?

[dag1011]

Apologies if this is an obvious question but I have googled and gone through other posts to no avail.  All the stuff I read about Sure Signal focuses on improving data connections (3G etc), but doesn't seem to mention if it ups the signal/coverage for voice and for SMS.  Does it also do this?

Thanks

Yes it does. 3G is a voice and data service and a Sure Signal gives a perfect 3G signal for both.
