Longquan belongs to Chengdu. Your Jianyang card goes back to Chengdu Jianyang for 3.6 cents a minute. However, if you have a Jianyang card, you can call Chengdu, Meishan, Ziyang and Jianyang without going out of Jianyang. Your package will be deducted. Your friend told you to buckle your bag in Jianyang because he is a local and you can't. Unless you are a global phone, you can deduct the minutes of the package wherever you go. You don't have to worry.
