Take Jiangsu Unicom as an example: If you apply for a Shanghai Pudong Development Bank small-issue card and a non-premium number Pudong Development Bank card, there is no contract period. If you apply for a Pudong Development Bank card and it is a prestige number, there will be a prestige-number agreement period ( The agreement period is generally the month of joining the network and the following 12 months. For the specific premium account agreement period, please see the order filling and number selection page), and premium account fees are waived. Pufa small-issued cards cannot apply for prestige accounts.
