查询SIM卡正在使用的订单中使用的imsi,在运营商侧该imsi剩余流量。 仅能返回1个imsi的流量数据,若该SIM卡存在多个imsi将存在数据错乱的可能。 该功能仅对特定资源的imsi使用,具体资源支撑情况请咨询领科支持人员。Query the IMSI used in the order that the SIM card is in use and the remaining data by MNO side. Remaining data of only one IMSI can be returned. If the SIM card has multiple IMSI, data may be incorrect. This function applies only to the IMSI of specific resources. For details about resource support, contact the Linksfield support personnel.
