It took only a tweet and an email to fix my friend’s problem. I hope they will fix this bug in their system, but thumbs up for the great customer service.
In details, I tweeted MTC Touch about the problem linking them to the blog post and I emailed the person who helped me set up the 3G pilot testing a few months back. They replied to me within 15 minutes and told me that the problem can be fixed and activated the 1Gb plan on my friend’s number an hour later.
