Here is the comparison between the two keeping in mind the quality of the services and the features offered by them both:

Compatibility The system uses modern advanced technology. It enhances the business capabilities. GSM uses an old cellular technology and it doesn’t update as VoIP does for business development.
Hardware The hardware needed is quite less in comparison to GSM. Integration is possible by directly connecting to your PBX. GSM would need additional hardware installation. It cannot be integrated with existing hardware and systems.
Number Porting VoIP allows you to have a fixed-line number when porting. Porting a fixed-line number to a mobile GSM service is not
Connectivity VoIP doesn’t need mobile coverage. It works with any internet connection or a dedicated VoIP line. GSM requires a mobile network coverage in the area, without this it will not work.
Call Rates The VoIP calls rate can be reduced substantially. The call rate cannot be reduced as it is in the case of VoIP
Quality The quality of calls is excellent. Blazon offers a 99.9% uptime rate. The quality of calls is not as crystal clear as internet calls.
Scalability A single SIP trunk can be used to route all inbound and outbound calls. There is less use of equipment and high productivity. One GSM cannot support more than one call at a time with putting a call on hold.

VoIP allows you to make and receive calls nationally and internationally at unimaginably reduced at rates. Any internet connection can be used for VoIP services. The service provider can connect it to the cloud-based PBX of your company so that you can have access to calls and voice mails remotely and while you’re in your office premises.
