GPRS monthly 10 yuan 80M how good the card?

I am in Liaoning province, hundreds of GPRS needs of the sim cards used in monitoring the power grid.
Currently there are 10 yuan monthly, but because they are not the Liaoning Mobile cards, there are a variety of issues
1, ex Payment difficult and often arbitrary increase in services, leading to increased costs.
2, if inadvertently arrears, the monthly package on the cancellation, in accordance with 1kb3 cents to charge
3, no arrears Notifications, which must continue to send cards to whether there are arrears, we made an automatic landing system, but due to the certification system is always changing, and we always have to modify the software to adapt to very tired.

We hope to find a partner we can provide services like
1, continued to provide monthly 50-80M of the cards, 10-12 yuan per month
2, to take the collection method would not Off the arrears
3, if the collection can not provide functionality to remind the arrears, as they stuck in the equipment, have not received the text message function, reminds us of the need to direct it.We have received a timely reminder to pay can be .
4, a monthly subscription model will not be changed, will not be set or increase the cost of other
5, due to high demand of the card, and so on, will not lead to internal movement of the reasons leading to disruption of service or raise the monthly Cost

Liaoning no such concessions to the monthly card.
