RAIN INTERNET CONNECTIVITY APPALLING

I purchased a RAIN Sim card and was promptly delivered. Little did I know that this is the beginning of bad connectivity. I have been having issues with my Telkom internet and my router has been booked in for repairs. I was looking for an alternative, hence I decided to try RAIN. What a bad choice I have made. I am connected for 2 minutes and disconnected for 5 minutes or more. The network is sooooo poor. I regret my decision to give them a try. I wish I had checked the reviews before purchasing the SIM card. Now I am back to use my phone as a Hotspot- should have just remained with my Hotspot and waited for Telkom to finish with my router. Yes I have issues with Telkom, but their internet is far much better than the APPALLING RAIN NETWORK!
