Internet - adsl or lte...plz help

Hello everyone

Sorry to trouble you all but i really need help...

I am looking for an internet package most suitable for international online teaching of which requires a 10meg line and above.

Unfortunately according to Telkom technical support i only have 6megs and below coverage in my area.

Telkom gave me a 10meg adsl uncapped contract but two weeks later the installation guy says he is ready to install but can only offer me a 6meg line...i cancelled that contract...

According to telkom, afrihost and mweb...the best and only option for me now is LTE...i am due for an upgrade on one of my telkom contracts...telkom currently has a double data promo...

Can someone please assist me with advice on LTE packages according to his/her experience using LTE for online teaching...

I do not want to take the wrong contract and then experience problems and also end up paying for something that is not helping me...or data being used up too fast...

Please help

Thank you
