The 3GB for $35 plan was discontinued for the XOOM. I'm disappointed that VZW is determined to do things differently for iPad users and other tablet users. I hope that my usage stays low enough for the 1GB plan.
We were having a special promotion for the mobile hotspots that had a 3GB allowance that has been discontinued as of 5-10-11. However, if you have a Motorola Xoom that has a built-in data connection and not the Wi-Fi only version (meaning you don't have a MiFi), then you can still switch to the plan!
Just give us a call or PM me to switch your plan at any time. As of right now, the 3GB - $35.00 Mobile Broadband Plan is still on for all the tablets that have a built-in connection!
I hope that answers your question!
