I can't enable my sim card from abroad.

I left the UK 6 months ago, but I keep my US sim card. I need to go through a validation process, where I receive text messages, but I CANNOT receive them. I topped up £5 to my number and it doesn't work either. I called the EE contact numbers, but it was impossible. I also wrote to 150, but it still doesn't work. I cannot receive or send SMS.
