Vodacom has tripled the number of LTE enabled base stations on its network.
There are 200 stations in Johannesburg, up from just under 70 at launch, the network announced.
Additionally, Vodacom confirmed that testing has begun in Cape Town.
LTE, which stands for Long Term Evolution, is a new generation of mobile technology with the capability to operate at exponentially faster speeds than 3G.
"LTE represents a step change in mobile capabilities. Thanks to faster speeds, we’re able to unlock the true potential of smartphones, tablets and other mobile devices," Zunaid Dinath, Vodacom’s Chief Officer Sales and Distribution said.
"LTE has the ability to deliver stutter-free video and almost instantaneous music and picture downloads; and because it's mobile, we can deliver this experience whether you're at your office, on the move, or at home."
In addition to the wider network coverage, Vodacom now has LTE devices on sale at Vodacom World in Midrand and selected Vodacom outlets across Gauteng. Customers can now buy the Samsung Galaxy S III LTE, Vodafone K5006 and Alcatel One Touch L100V LTE dongle modems.
The Samsung Galaxy SIII LTE is available on a Smart Standard 229 package for R449 per month, which includes 1GB of data per month for three months.
The USB modems are available on various MyMeg packages, ranging from 500MBs (R129 per month) to 10GBs (R749 per month).
The LTE service is currently available to Vodacom Contract customers and will be available to Top-up and prepaid customers in 2013, Vodacom confirmed.
The LTE devices will automatically switch to the 3G network when LTE coverage is not available.
