For the past few weeks, each time I try to signup for AWS the automated phone call for verification doesn't hit my phone. I'm using real SIM cards of an African country inserted in a phone which I have with me. Been tryna figure out why the call doesn't come in anymore, it used to work fine before. I keep retrying until I'm blocked for 12hrs. Tried changing IP addresses and cards but still same. Is the automated phone call working for you? Which country did you create an account from? Every help and/or advice/suggestion will be highly appreciated.
