Hey guys. If you have a LTE setup greydot mobile with sip option is for you.
Setting up the sip portion of it means you make VOIP calls for just R0.29 per minute to local cellphone numbers and R0.18 per minute to landlines.
You don't get better than that and you can send faxes from the web portal by email or uploading your document and send sms too....
They also spoof your mobile or landline number to show calls as if you were actually calling from your cellphone or landline.
Yeah pretty awesome. I set it up in my B315 router with Telkom LTE now and it works pretty well.

If you want to try it out. They give you R3 free to test the service. Allows for call back service too if you out and about and need to make calls. Thos calls are charged @ R0.59 per minute.
