STEM offers ADSL as a best effort service. ADSL remains one of the most popular internet connections as it utilises the Telkom copper cable infrastructure that is implemented and accessible almost everywhere countrywide. STEM offers ADSL and VDSL predominately as fail over links on some of our ower-end Service Level Agreements. ADSL is however starting to get phased out since Fibre has not only become more affordable but has also grown to be the most reliable service for small to medium businesses.
