Does Rain really Work?

I ordered a Rain sim card and it took over a week to be delivered. Eventually when it was delivered I received a notification that the sim card is active. My cellphone takes 2 sim cards and currently have the Rain sim in my phone but still it registers as No sim.

I called the Call Centre and was assisted to load the APN settings and was told I should wait another 2 hours and it still does not work. It has been over a week now I am being told that its escalated and will receive a call. I have been calling everyday and I am told the same remark .

Its going to be another month and will have to pay for something I did not use.

I am having doubts that Rain really works or is it just a marketing gimmick.
