My sim has just stopped working and i really need that number working as it is my verfication method for many things. I tried to contact with no luck. Im am disgusted that you cannot contact them for free when you have an active bundle (calls, text, data, and worldwide calls) surely you should be able to contact any provider for free when this is the case. I really need to speak with an advisor to try sort this out asap. But will this happen? Your guess is as good as mine!!
