Why can't my card find the roaming place?

If you are referring to the itinerary inquiry, after logging in to the mobile phone business hall, you can view it by clicking Services > Epidemic Prevention > Travel Assistant. If you can't find out through the above methods, due to the differences in business policies of different cities, it is recommended that you contact your Unicom customer service for consultation and feedback. The specific situation is subject to local policies. If you have any questions, please click /qALCW for consultation.
