The Sirius/XM Lifetimes all come with their own terms & conditions. It would be a smart idea to before dropping a few hundred bucks on a specific service, that you read those. Lifetime subscriptions are transferable, but there are rules.
1. Lifetime bought & placed on an OEM radio BEFORE September of 2007, can be transferred to either another OEM & MUST stay there for the life of the that RADIO, or a portable radio with two other transfers available to that specific lifetime. Any purchased after that, follow the updated terms & conditions
.2. When swapping out a lifetime, there is a $75 swap fee, UNLESS, that radio is specifically broken, damaged, or stolen. In the case of a broken, damaged, or stolen radio, the swap fee is waived. It's hard to convince a representative to waive the swap fee just because you don't feel like you should have to pay it. It's in the terms & conditions, and Lifetimes are non-refundable & most likely, they aren't allowed to be canceled.
3. A Sirius Lifetime can be swapped for an XM Lifetime, & vice versa. The same swap fee applies. It takes more time because a support line has to be contacted by the agent you're speaking with to credit the new Sirius/XM account the price of what a Lifetime is now. If you have a lifetime with FREE INTERNET, it will not be transferred unless you're simply doing a hardware swap. Losing your free internet subscription is completely out of the hands of any agent. There's no button or special code that can bring that back, it will be lost forever.
If you call in demanding things in regards to your Lifetime, (i.e.) waiving the swap fee, transferring an OEM to another OEM, ect., it most likely won't be done. If you're nice & patient, & get the right representative, there is a CHANCE that it may be done.
