So I have both a DX and a Tbolt. I want the ability to switch back and forth between the two. I understand that the sim card will be deactivated if I don't switch back to the tbolt within 90 days. That's not a problem since I won't be off it that long. I was wondering if it would affect my pricing plan at all. I pay $9.99 for unlimited data from a past promotion. I asked a trusted source and he said no. Calling customer service told me the same thing. I would like to know any experiences you all may have. Thanks Sent from mah TBolt using teh Tapatalk.
