Can I use the avatar card on my mobile phone?

A mobile phone can hold cards of two different networks. In general, if your mobile phone is a 1G dual-card mobile phone, you can use mobile phone cards of different networks. This means that a mobile phone can use two mobile phone cards at the same time, but you can't make a phone call or send some short messages at the same time, so a mobile phone can hold two mobile phone cards from different networks.
