Hi, I have a plan upgrade offer with my positive tab of 150$. I want to get the essential; using my tab offer I will only have to pay $50 for it and then have a medium tab of 15$ extra per month on my bill. So that part I understand. I just want to make sure I will not be losing my existing rate plan of $40 a month with 1G of data. I upgraded to this promotion plan a few months ago and I dont want to lose it if I upgrade to this new phone. Can you let me know if I get to keep it?
