hi checkz, luinard is right, you can get the LTE either terminate you current plan or apply a new plan.
It doesn't work that way. I agree to both @hcescalaand @liunard1928. Terminate your existing service with Globe. You have to pay the terminate and admin fees. If you really want to have the Note 2 with LTE, add it as an additional line if your credit limit is sufficient. If you decide to get an extra line, please drop by in a Globe Business Center and bring with your valid ID cards.
Hope this helps.
