What mobile card is suitable for me when I often make phone calls and send text messages?

The packages vary depending on the location. Over here, M-Zone launches an online chat package. The base fee is 12 yuan, 100 text messages, 50M Internet traffic, making a call seems like 20 cents per minute, and after 2 minutes it seems like 10 cents per minute. If you send text messages frequently, you can pay another 10 or 20 yuan. Send 300 or 500 text messages

For details, you can ask at the local business office.
