I saw a video of someone using a high gain lte antenna with a rain sim and getting speeds up to 100mbps. I decided to test it out, ordered the antenna, activated and rica'd the sim, but rain has been upgrading their systems supposedly and my sim is neither active nor does it appear on my rain profile. Today is already the third day and still nothing. Calling customer service is a waste of time, one of the consultants even lied to me, gave me a fake name and told me they did not give call ref numbers. The 3 other times I got their standard response that it takes 2-24 hours for the sim to activate, 2-24 hours for customer service to get back to you, and still I haven't been contacted. It's been a terrible start. Out of curiosity, has anyone used rain with a high gain antenna?
