The 2 are exactly the same in capabilities and features. 1 is just a newer model device. You can get support at Sprint.com/Airave. Please let me know if you need anything else.

Thank you for your post.
As mentioned by Heather, the device is identical to the 2.5. We have discontinued the 2.5 to make room for the 2.5 , but all features are the same.
If there is anything further I can assist we can assist you with, please let us know.
