Installing system using IQ4 panel - moving to Surety considerations

I have a quote for a system installation using Quolsys IQ4 (they’re the only company I could find in my area that will install without a contract). I know Surety is compatible with Quolsys IQ4, but I want to triple check everything before agreeing to the installation as I would like to use Surety for monitoring. The website FAQ says all Surety needs is cell signal for the system. However, I live in a place with poor-ok cellular service. How would I go about making sure the system will be able to be used with Surety? Especially since I have another company coming out to do the installation? What other considerations might I be missing? Thanks!
