Apple a2 103 is the mobile priority version, which means that if you use both the mobile card and Unicom card, you must set the mobile card as the main card to use 4G.

Mobile Priority Edition is a mobile phone jointly launched by mobile and mobile phone manufacturers. When using a single card, it is no different from the public version, while users using dual cards use mobile 4G traffic by default when using mobile cards and other non-mobile cards. Other non-mobile operators are 2 and 3G signals, which cannot be changed. When using mobile card+mobile card, it is no different from the public version. The use of non-mobile card plus non-mobile card is also consistent with the public version, but it is impossible to use two telecom cards at the same time.
