I've been having so much trouble switching from another carrier over to us mobile. After numerous calls with several representatives and spending 30-60 minutes with each call, the switch was unsuccessful. Some of the representatives are not trained very well to troubleshoot the problem and would give me all sorts of excuses ie. your transfer pin is wrong (it was not), your IMEI was incorrect, etc. I figured I'll just call back until I get someone that knows what they're doing, that person was Khurraim. He knew what to do and was on the phone with me the entire time until we were able to switch over. It was obvious he was more knowledgeable and experienced. Khurraim spoke great English and that made the phone call go much smoother, unlike some of the other agents that barely speak English so there was definitely some difficulty in comprehending. Ask for Khurraim if the other agents can't help you. Glad he was able to finally resolve the issue.
