What software can a tablet computer that can't insert a card send text messages?

Fetion, download one and send it to friends of mobile users for free. Non-friends will be charged.

139 mailbox, non-friends and off-network, such as Unicom Telecom, can also use the SMS function in 139 mailbox. Because the tariffs in each province are different, it is cheaper to go and see for yourself, and there are gifts every month. You can also make calls from 3G phones in 139. Take a moment to look inside.

If you are satisfied, please confirm my answer and give points. I used this. I can make 3G calls in Guangdong, but not in Hubei. . But there's nothing wrong with texting.

The rest is really gone.
