I really wish they would get Ting out of the Beta stage for porting over your old phone and phone number. I feel better support of porting over phones and #'s would lead to Tucows getting many more customers to transfer over to Ting.
Not sure about the Beta stage but last weekend I ported over my phone number to Ting and I had an inactive Sprint HTC EVO 4g that I activated during the transition. I plan to port over another family members number this weekend. I'm completely satisfied with the process and their plans / pricing fit our usage very well.
It does seem to be easier if your phone is inactive. I guess my issue seems to be since my phone is active and I would also like to port over the same phone # I have now. Plus the phone I have is not one that is supported. So it kind of seems like it is up to me to figure it out. I hope they can streamline this process and make it easier in this scenario. I do agree that the plans and pricing seem to be great and that is why I want to move my phones over and fast.
