These devices need to be replaced by an MTS technician and can't simply be swapped out at a connect store. If you are having any technical troubles with the device give our tech support group a call and they can look into setting up a repair appointment to have it replaced. If the device is still in good working order however and you are just looking to upgrade you would be best to speak to our sales department to see what options are available in your area. They can be reached by calling 204-225-5687.
