In the support faq's for transferring your current number to a Straight Talk phone, it says that "Your new Straight Talk will be ready to complete activation when your old phone stops working."
The old phone stopped working several days ago, and a Straight Talk representative told me that the number had already been switched to them, but I still haven't been able to activate the new phone. Instead, I keep getting the same message that says, "Your transaction can not be completed at this time. Your telephone number is in the process of being switched between carriers. Please call 1-877-430-CELL (1-877-430-2355) from a landline phone to check on the status of your number transfer request.
When I called customer service I was told that there were some "technical difficulties", but that the problem should be resolved within the next four hours. I called back after nearly twenty-four hours had gone by to see why the phone still couldn't be activated. A new representative told me she was going to put me on hold while she researched the problem.
However, she must not have known how to place a person on hold, and I got to listen to her laughing and joking with other "workers" for the next 33 minutes while she "researched". When she did take me off of "hold" she told me first that it would be another 72 hours before the phone could be activated. Then she changed her mind to 24 hours, then to 48, then to between 24-48 hours. She couldn't give me any reason for why the phone wouldn't work yet.
If the phone ever starts working, it still looks like a great deal cost-wise, but I pity anyone else who has to try to deal with their customer service, or complete lack of it.
