Global System for Mobile (GSM) was not only the first mobile telecommunications system in the world, but also the most popular one. GSM is like the old man that was once the popular jock at high school. His looks have faded, the knees have given in a bit, and the six pack has turned into a serious dad bod – but his kids still think he is cool, well they’re teenagers now, so… The reality is GSM is fast becoming outdated with the rise of a younger, fitter, more visionary Voice Over Internet Protocol (VoIP) technology.

Why VoIP is becoming more relevant than GSM

Compatibility with modern technology:
While GSM is the OG (Original Gangsta) of mobile telecommunications and is still used today, it simply is not as compatible with modern technology as VoIP is. More and more businesses are moving their technologies to the cloud. Having a GSM account as opposed to a VoIP account will limit your business capabilities.

Hardware needed:
VoIP requires less hardware as new telephony integrates seamlessly with VoIP providers. VoIP can connect directly to your PBX, whereas the old school GSM will need additional hardware to do the same thing. Less hardware – less costs.

Number porting:
With VoIP you can keep your fixed-line number (011, 010, 021) when moving over to VoIP services. You can’t port a fixed-line number to a mobile GSM service. Imagine the headache and cost of new business contact details.

Connectivity:
GSM will only work when there is mobile network coverage in the area, whereas VoIP does not rely on mobile coverage. Instead, it works with any internet connection or with a dedicated line to a VoIP provider – there is no need for internet at all in this case.

Call rates:
Since VoIP call rates are goverened by ICASAs interconnect call termination rates, they can be substantially reduced in comparison to GSM call rates. GSM call rates are governed by the fees charged from a variety of mobile network providers it has to connect with in order to make your call. Seriously, who wants to pay a higher phone bill?

Quality:
The quality of a VoIP call exceeds that of a GSM call. This is based on the Mean Opinion Score (MOS – measures subjective call quality) for VoIP calls, which is 3.5 – 4.2 out of 5. GSM calls are scored 2.9 to 4.1 out of 5.

Scalability:
An entire enterprise can have all their inbound and outbound calls routed from a single SIP trunk. One GSM sim card can only support one call. VoIP allows you to utilise less equipment and produce a higher level of productivity.
