A South African company that helps business and consumers minimise their cellphone bills has released a study that shows that, for most, switching your mobile package after two years can save you money.
Tariffic found that on average consumers can save 18% on their cellphone bills after 18 months by upgrading to the right contract - well, except if you're with Vodacom.
"By optimising your contracts every time they expire, you can save an additional 18% which is a total saving of nearly 50% on your original cellphone bill," Tariffic CEO Antony Seeff said.
The Tariffic Tracker, which is the report that investigated costs, took only SIM-only deals into account - since handset contracts radically differ based on the phone you are purchasing.
The report also excluded short-term bundles.
So what did the report find?
Due to the frequent introduction of new packages by mobile providers every year, consumers can find a way to reduce their costs through the right package.
The tracker also found that Telkom and Cell C have the cheapest voice contracts, while Vodacom is more often than not the most expensive provider of voice packages.
Telkom's new FreeMe packages are offering a 29% saving when compared to their previous packages, while MTN users can save up to 33% through MTN's MyMTNChoice+ Packages.
Vodacom however has increased prices for their Smart contracts over the last 18 months.
Meanwhile Cell C's Pinnacle packages are recommended as the best choice for three quarters of Tariffic users.
Despite so many new packages however, there has been little change when it comes to data contracts.
